MVVMCross ListView - How to display a list of items in a listview grouped by a status? For exampled activate or deactivated
I have added two listview to the layout and set the datasource to have two lists (activatedItems and deactivatedItems => both of them derived from ListOfItems. ) using the xaml data binding with now code behind. But had a problem in the data not updated when there is a change to the underlying list (ListOfItems).
To resolve this, I have to re create the UI by setting the content view whenever there a change to the data set.
This is not an elegant solution and I would like to have one listview with sections "Activated" and "Deactivated". Then on touching the Activated item should get added to the Deactivated list and the UI should reflect the same.
Since you have a LoginItemModel with a Title property (let's assume it's a string property), I would recommend you to extract this to an ILoginItemModel interface and also add a bool IsHeader property. This way:
public interface ILoginItemModel {
public bool IsHeader { get; }
public LoginSection ItemGroup { get; }
public string Title { get; }
}
Make your LoginItemModel extend this ILoginItemModel interface and make IsHeader always return false.
public bool IsHeader => false;
Write a second class extending this same interface, let's call it LoginItemHeaderModel. This class will just have these three properties:
public class LoginItemHeaderModel : ILoginItemModel {
public bool IsHeader => true;
LoginSection _itemGroup;
public LoginSection ItemGroup => _itemGroup;
string _title;
public string Title => _title;
public LoginItemHeaderModel(LoginSection itemGroup, string title) {
_itemGroup = itemGroup;
_title = title;
}
}
Now we have two models that fits into a single IList<ILoginItemModel>.
Back to your view model, you can declare a fourth list property and put it all together along with your new headers:
public List<ILoginItemModel> SectionedLoginItems {
get {
var values = Enum.GetValues(typeof(LoginSection)).Cast<LoginSection>();
List<ILoginItemModel> list = new List<ILoginItemModel>();
foreach (LoginSection loginSection : values) {
list.Add(new LoginItemHeaderModel(loginSection, loginSection.ToString()));
list.AddRange(LoginItems.Where(l => l.ItemGroup == loginSection));
}
return list;
}
}
Now you have your single sorted and with section headers list.
You should now write a new layout for those header items (aren't you going to make them look like the common items, right?) and, in your custom MvxAdapter, inside the GetBindableView method, check whether the object source (which will be an ILoginItemModel object) is a header item or not.
Whenever you make a change to ActiveLoginItems or DeactivatedLoginItems, make a call to RaisePropertyChanged in your ViewModel i.e.
RaisePropertyChanged(() => ActiveLoginItems);
or
RaisePropertyChanged(() => DeactivatedLoginItems);
That should make the MvxListView update with the changes.
I'm writing a plugin for a TFS process.
I need to get the Project Name from the TeamFoundationRequestContext whenever a work item is in the process of saving.
Normally I can get the work item ID because the record has already been saved. However, when the work Item is being saved the first time, I do not have a way to get the work item ID.
My question is how can I get the Project Name from the TeamFoundationRequestContext when the work item saves for the first time.
Here is a class that captures the work item changed event and checks to see if it is a newly created work item.
From within the event if it is a newly created work item you can then do what you need with the Project name that is associated with that work item.
using Microsoft.TeamFoundation.Framework.Server;
using System;
using Microsoft.TeamFoundation.Common;
using Microsoft.TeamFoundation.WorkItemTracking.Server;
namespace TfsProcess.CaptureProjectNameOnNewWorkItem
{
public class CaptureProjectNameOnNewWorkItem : ISubscriber
{
public string Name
{
get
{
return "CaptureProjectNameOnNewWorkItem";
}
}
public SubscriberPriority Priority
{
get
{
return SubscriberPriority.Normal;
}
}
public EventNotificationStatus ProcessEvent(
TeamFoundationRequestContext requestContext,
NotificationType notificationType,
object notificationEventArgs,
out int statusCode,
out string statusMessage,
out ExceptionPropertyCollection properties)
{
statusCode = 0;
properties = null;
statusMessage = String.Empty;
try
{
ProcessNotification(notificationType, notificationEventArgs, requestContext);
}
catch (Exception exception)
{
TeamFoundationApplicationCore.LogException("Error processing event", exception);
}
return EventNotificationStatus.ActionPermitted;
}
private static void ProcessNotification(NotificationType notificationType, object notificationEventArgs, TeamFoundationRequestContext requestContext)
{
if (notificationType == NotificationType.Notification && notificationEventArgs is Microsoft.TeamFoundation.WorkItemTracking.Server.WorkItemChangedEvent)
{
var ev = notificationEventArgs as WorkItemChangedEvent;
if (ev.ChangeType == ChangeTypes.New)
{
//Do somethin with the project name of the newly created work item
// projectName = ev.PortfolioProject;
}
}
}
public Type[] SubscribedTypes()
{
return new Type[1] { typeof(WorkItemChangedEvent) };
}
}
}
Update:
You could create a plugin implementing the ITeamFoundationRequestFilter interface, which gets executed BEFORE or AFTER Team Foundation Server receives and processes requests. This allows you to validate work items and cancel the creation of the work item if it is not valid based on some logic for instance.
Here is a link to blog with a implementation of this that will cancel the creation of the work item if it is being created by a certain user.
Getting information from a TFS Request
How to implement ITeamFoundationRequestFilter
In order to get the Work Item ID you will intercept the xml soap response and parse it for the work item value.
Using the filter plugin you can filter for any of the methods responsible for updating, creating and querying work items.
The blog goes into more explanation and implementation.
The WorkItemChangedEvent event has a PortfolioProject property, so you should be able to get it like this:
var ev = (WorkItemChangedEvent)notificationEventArgs;
var projectName = ev.PortfolioProject
I cannot for the life of me get this to work with my existing code, but I am trying to save my enum selections as strings in NHibernate. Basically, I have a UI check box and if the user selects multiple check boxes I want to store those selections. Now, I can get NHibernate to store ONE selection (e.g., from a drop down or radio button list, where the user is limited to one choice only).
This is the jist of what I have for an enum:
public enum IncomeType
{
[Display(Name = "Full-Time Employment")]
FullTime,
[Display(Name = "Part-Time Employment")]
PartTime,
[Display(Name = "Self-Employment")]
SelfEmployed,
[Display(Name = "Rental")]
Rental,
[Display(Name = "Social Security Payments")]
SocialSecurity,
[Display(Name = "Retirement / Pension Payments")]
Retirement,
[Display(Name = "Child Support Payments")]
ChildSupport,
[Display(Name = "Spousal Maintenance")]
Maintenance,
[Display(Name = "Other")]
Other
}
I use a method to "select" whether a checkbox list is shown (if my BulkItemThreshold equals the number of options, a checkbox list is displayed). Here is that method:
public static IEnumerable<SelectListItem> GetItemsFromEnumString<T>
(T selectedValue = default(T)) where T : struct
{
return from name in Enum.GetNames(typeof(T))
let enumValue = Convert.ToString((T)Enum.Parse(typeof(T), name, true))
select new SelectListItem
{
Text = GetEnumDescription(name, typeof(T)),
Value = enumValue,
Selected = enumValue.Equals(selectedValue)
};
}
(Note: some items in there are helpers, but I don't believe they are relevant; also, the selected input is displayed using a template .cshtml file - again, not sure if that's relevant)
Now, I call this thusly:
public class IncomeTypeSelectorAttribute : SelectorAttribute
{
public override IEnumerable<SelectListItem> GetItems()
{
return Selector.GetItemsFromEnumString<IncomeType>();
}
}
And finally, we get to the virtual property (using a proxy) but this is where NHibernate throws a wrench (Note: this was working fine for me before NHibernate, and now I am trying to get many lines of code working with it WITHOUT having to re-do everything; if I re-do everything I will probably triple the code I already have to get it to work):
Property (record):
[IncomeTypeSelector(BulkSelectionThreshold = 9)]
public virtual List<string> IndividualIncomeTypeCheckBox { get; set; }
proxy (part):
public List<string> IndividualIncomeTypeCheckBox
{
get { return Record.IndividualIncomeTypeCheckBox; }
set { Record.IndividualIncomeTypeCheckBox = value; }
}
Again, this is how I was doing things and it was working great before NHibernate. But now I have to use NHibernate. No getting around it.
I am using a service class that it tying the two together in a Create method to save in the DB with NHibernate, and for the above it would ordinarily look like this:
part.IndividualIncomeTypeCheckBox = record.IndividualIncomeTypeCheckBox;
This would work if it were just one selection.
Well, I've spent a good two (2) months trying to get this to work. It's tough because I have lots of code where the user can make only one selection (such as with a radiobutton list) and it works GREAT - even with NHibernate. Let me give you an example:
public virtual IncomeType? IndividualIncomeTypeCheckBox { get; set; }
If I do the above, it will display a drop down list, and NHibernate will store the ONE allowable option selected by the user in the DB no problem. But more than one option with List<string> does not work.
Now, I have tried everything I could find here or elsewhere and nothing works. Yes, I know it should be IList<IncomeType> or some other variant. But if I use this then NHibernate requires that IncomeType be another table in the DB. This is too much code to write for such a simple thing I believe. We are not talking a many-to-many relation in the sense that this is not a User with Multiple addresses (wherein addresses would have street, city, state, zip, etc.).
I have tried different types of proxy get and set code, but nothing works. I have tried [Flags] and other things working with string only, but to no avail. Those last solutions would "work" but ONLY to save the first item selected out of multiple (i.e., in my scenario, if the user selected "FullTime" and "Rental" as Income Types, then only "FullTime" (string) would be saved or "1" ([Flags]/int), not both items selected.
I have a situation where I re-display the choices using a ReadOnly attribute like this:
[IncomeTypeSelector]
[ReadOnly(true)]
public List<string> IndividualIncomeTypeCheckBoxPost
{
get { return IndividualIncomeTypeCheckBox; }
}
This would display on the UI, but I tried doing something like this with NHibernate and it wouldn't work.
Could anyone please show me, using the above, how I can go about getting NHibernate to store more than one enum in this checkbox list scenario?
UPDATE:
More poking around here and on the web, and I came up with the following (which still does not work).
Property (record):
[IncomeTypeSelector(BulkSelectionThreshold = 9)]
public virtual IList<IncomeTypeRecord> IndividualIncomeTypeCheckBox
{
get { return incomeType; }
set { incomeType= value; }
}
private IList<IncomeTypeRecord> incomeType =
new List<IncomeTypeRecord>();
Proxy (part):
public IList<IncomeTypeRecord> IndividualIncomeTypeCheckBox
{
get { return Record.IndividualIncomeTypeCheckBox; }
set { Record.IndividualIncomeTypeCheckBox= value; }
}
And a change to the enum:
public enum IncomeType : int // removing int & value still gives validate error
{
[Display(Name = "Full-Time Employment")]
FullTime = 1,
[Display(Name = "Part-Time Employment")]
PartTime,
....
}
And I added this class to support IncomeTypeRecord
public class IncomeTypeRecord
{
public virtual int Id { get; set; }
public virtual IncomeType Value { get; set; }
}
HOWEVER, when I get to the UI screen and pick one or more options I get a validation error (value not valid). For example, say I pick FullTime alone, or pick FullTime and Retirement, then the UI will display the following error:
The value 'FullTime' is invalid.
The value 'FullTime,Retirement' is invalid.
(respectively)
Even if I remove the int declaration for the enum and get rid of the value I started with "1", I still get this validation error. I tried messing around with and adding different model binders (which now has me stumped as to whether my original problem still exists and now I have a different problem - but you still get bounty points :) ).
Pulling my hair out. If I could offer more bounty I would. I need a definitive solution. I appreciate any help.
UPDATE
This is what I have so far:
Record:
public virtual string IndividualIncomeTypeCheckBox{ get; set; }
Part:
//If I do IEnumberable<string> my .Select throws a cast error
public IEnumerable<IncomeType> IndividualIncomeTypeCheckBox
{
get
{
return Record
.IndividualIncomeTypeCheckBox
.Split(',')
.Select(r => (IncomeType)Enum.Parse(typeof(IncomeType), r));
}
set { Record.IndividualIncomeTypeCheckBox= value
== null ? null : String.Join(",", value); }
}
Service Class:
public SimplePart CreateSimple(SimplePartRecord record)
{
SimplePart simple = Services.ContentManager.Create<SimplePart>("Simple");
...
//How I would save a FirstName property (example Part / PartRecord below)
//public virtual string FirstName { get; set; } - PartRecord
//public string FirstName - Part
//{
// get { return Record.FirstName ; }
// set { Record.FirstName= value; }
//}
simple.FirstName = record.FristName;
...
//I obviously cannot do the following with the above IncomeType
//Getting cannot convert string to IEnumerable error
//How would I write this:
simple.IndividualIncomeTypeCheckBox = record.IndividualIncomeTypeCheckBox;
...
}
And this is how it's called in a controller (this persists to DB): (Updating Controller code)
public ActionResult Confirm(string backButton, string nextButton)
{
if (backButton != null)
return RedirectToAction("WrapUp");
else if ((nextButton != null) && ModelState.IsValid)
{
_myService.CreateSimple(myData.SimplePartRecord);
return RedirectToAction("Submitted");
}
else
return View(myData);
}
Updating with additional code (serialization and view model):
"myData" is defined in the controller (using Serialization) as:
private MyViewModel myData;
protected override void OnActionExecuting(ActionExecutingContext filterContext)
{
var serialized = Request.Form["myData"];
if (serialized != null)
{
myData = (MyViewModel)new MvcSerializer().Deserialize
(serialized, SerializationMode.Signed);
TryUpdateModel(myData);
}
else
myData = (MyViewModel)TempData["myData"] ?? new MyViewModel();
TempData.Keep();
}
protected override void OnResultExecuted(ResultExecutedContext filterContext)
{
if (filterContext.Result is RedirectToRouteResult)
TempData["myData"] = myData;
}
I use Serialization because I set up a multi-step wizard (as seen in the controller action "backButton" "nextButton) on the front-end. I am not using a driver (which can only display Admin or on the front-end but then only on .cshtml files directly under the ~/Views folder (not in a structured folder list like I am using)). No driver = no update view model type code = no mechanism to "create" the data in the DB. If I do not use some "create" type method, the form will submit but all the data will be "NULL".
When you say that the data should be persisted automatically, I am sorry but I do not see how. All the stuff I read or code I review has SOME method of updating the DB with whatever is entered in a form. If I am missing something, my apologies.
"MyViewModel" is pretty straightforward:
[Serializabel]
public class MyViewModel
{
public SimplePartRecord SimplePartRecord { get; set; }
}
And, just in case, here is the relevant portion of the migration (return 1 is a completely separate and unrelated table):
public int UpdateFrom1()
{
SchemaBuilder.CreateTable("SimplePartRecord",
table => table
.ContentPartRecord()
...
.Column("IndividualIncomeTypeCheckBox", DbType.String)
...
);
ContentDefinitionManager.AlterPartDefinition("SimplePart",
part => part
.Attachable(false));
return 2;
}
The error I am getting is
Cannot implicitly convert type 'string' to 'System.Collections.Generic.IEnumerable'"
when I do the following in the "Create" method of my service class:
simple.IndividualIncomeTypeCheckBox = record.IndividualIncomeTypeCheckBox;
One additional thought: I tried using the n-n Relation sample to handle this scenario. Aside from it being a lot of extra code for what I thought should be straightforward and simple, because of the way I am using Serialization I had a lot of object reference errors and could not figure out how to properly code my controller to handle it.
There's a lot of info to wade through here so hopefully I haven't missed the point. It appears to me that the goals are:
The business class has a collection property of IList<IncomeType> without requiring an additional table
The values in that collection should be persisted as a delimited string of the enum names
The best approach is to use a custom user type (an implementation of NHibernate.UserTypes.IUserType) to map the property. Below is a generic IUserType that will map an enum of type T from an IList<T> property to a comma delimited string in the database and back again. There's no easy way to restrict T to an enum but the code will only work with enums.
Mapping a property using the custom type is simple with Fluent NHibernate:
public class Person
{
public Person()
{
IncomeTypes = new List<IncomeType>();
}
public virtual int PersonId { get; protected set; }
public virtual string FirstName { get; set; }
public virtual string LastName { get; set; }
public virtual IList<IncomeType> IncomeTypes { get; protected set; }
}
public class PersonMap : ClassMap<Person>
{
public PersonMap()
{
Table("Person");
Id(x => x.PersonId).GeneratedBy.Identity();
Map(x => x.FirstName);
Map(x => x.LastName);
Map(x => x.IncomeTypes).CustomType<EnumAsDelimitedStringType<IncomeType>>();
}
}
And here's the code for the user type:
public class EnumAsDelimitedStringType<T> : IUserType
{
public new bool Equals(object x, object y)
{
if (ReferenceEquals(x, y))
{
return true;
}
var xList = x as IList<T>;
var yList = y as IList<T>;
if (xList == null || yList == null)
{
return false;
}
// compare set contents
return xList.OrderBy(xValue => xValue).SequenceEqual(yList.OrderBy(yValue => yValue));
}
public int GetHashCode(object x)
{
return x.GetHashCode();
}
public object NullSafeGet(IDataReader rs, string[] names, object owner)
{
var outValue = NHibernateUtil.AnsiString.NullSafeGet(rs, names[0]) as string;
if (string.IsNullOrEmpty(outValue))
{
return new List<T>();
}
var getValueArray = outValue.Split(new[] {','}, StringSplitOptions.RemoveEmptyEntries);
return Array.ConvertAll(getValueArray, s => (T)Enum.Parse(typeof(T), s)).ToList();
}
public void NullSafeSet(IDbCommand cmd, object value, int index)
{
var inValue = value as IList<T>;
// set to string.Empty if you prefer to store that instead of null when the collection is null or empty
object setValue = null;
if (inValue != null && inValue.Any())
{
var setValueArray = Array.ConvertAll(inValue.ToArray(), v => Enum.GetName(typeof(T), v));
setValue = string.Join(",", setValueArray);
}
NHibernateUtil.AnsiString.NullSafeSet(cmd, setValue, index);
}
public object DeepCopy(object value)
{
return value;
}
public object Replace(object original, object target, object owner)
{
return original;
}
public object Assemble(object cached, object owner)
{
return cached;
}
public object Disassemble(object value)
{
return value;
}
public SqlType[] SqlTypes
{
get { return new[] {new SqlType(DbType.AnsiString)}; }
}
public Type ReturnedType
{
get { return typeof(IList<T>); }
}
public bool IsMutable
{
get { return false; }
}
}
I think you're on the right track pursuing a [Flags] enum. You may have done this, but just in case -- making an enum flags-worthy is more than adding the attribute. You also have to specify the value for the items in a binary-friendly manner. I've found the easiest way to do this is as follows:
[Flags]
public enum IncomeType : long // you'll need the room with several options
{
FullTime = 1,
PartTime = 1 << 1,
SelfEmployed = 1 << 2
// And so on
}
If you don't do this, then you'll get sequential integer values, which breaks the bitwise comparison that allows you to do multiple values in a single integer.
Your code to create the SelectList looks fine. Your options should construct form values that get posted back with the same name. If you want to use the default modelbinder, that means the associated property on your view model would need to be List<int>. If you're not using a view model (you probably should) you can pull it out of the forms collection.
Once you have this set up, then translating from your view model to your NHibernate entity is simple if a little annoying. You basically have to cycle through the values in the list and |= them onto your NHibernate entity's single enum property.
So let's assume you have a view model like this:
public class MyEditViewModel
{
public string Name { get; set; }
public List<int> IncomeSelections { get; set; }
// You'll probably have this to populate the initial view rendering
public SelectList AllIncomeOptions { get; set; }
}
You'll build your view using your helpers and all that, then build the checkboxes using the SelectList but making sure the input name is IncomeSelections, then when it's posted back you will push the view model data into your NHibernate entity something like this:
var myNHEntity = new NHEntity();
// If you're editing an existing entity, then be sure to reset the enum
// value to 0 before going into the following foreach loop...
foreach (var incomeSelection in viewModel.IncomeSelections)
{
myNHEntity.IncomeSelection |= incomeSelection;
}
There's probably a more clever way to do this, and you might have to cast the int to your enum type, but you'll figure that out (I'd do it for you, but it is Friday and I already have a beer open).
NHibernate should persist it without you having to do anything funky on the NH side.
In summary...
It seems like this is more a problem of how you handle the posted data than the NHibernate side. If you implement something like this, then be sure to use Fiddler or FireBug to inspect the posted values to make sure 1) they're integers and 2) the names are the same so they'll be added to the list.
Good luck!
The problem is simply that it won't be able to map a List without building a full relationship with an intermediate association table. It is way simpler to have the record store the values as a comma-separated string (so your record property is a string, not a list of string) and your part can map back and forth between string and List.
You can find an example of something very close here:
https://bitbucket.org/bleroy/nwazet.commerce/src/d722cbebea525203b22c445905c9f28d2af7db46/Models/ProductAttributesPartRecord.cs?at=default

It's not using enum values, instead it's a list of ids, but that should give you a good idea about how to make this work fairly simply: parsing enums you already know how to do.
Let me know if you need more details, but I think that's what you needed to get unblocked.
My situation is slightly different than from other posts and I was not able to solve it with the other trhreads. So that why I ask.
I have a class that is obtained from deserializing an XML like:
<?xml version="1.0" encoding="UTF-8"?>
<node>
<leaf>
<name>node 1</name>
<text>text 1</text>
<url>url 1</url>
</leaf>
<leaf>
<name>node 2</name>
<text>text 2</text>
<url>url 2</url>
</leaf>
</node>
so the class is:
[XmlRoot("node")]
public class csNodeList
{
public csNodeList()
{
Leaf = new csLeafCollection();
}
[XmlElement("leaf")]
public csLeafCollection Leaf
{
get;
set;
}
}
public class csLeaf
{
public csLeaf()
{
Name ="";
Description = "";
Address = "";
}
[XmlElement("name")]
public string Name
{
get;
set;
}
[XmlElement("text")]
public string Description
{
get;
set;
}
[XmlElement("url")]
public string Address
{
get;
set;
}
}
public class csLeafCollection : System.Collections.ObjectModel.ObservableCollection<csLeaf>
{
}
Then I have 2 Views, one to show all the leafs and one to edit one leaf. I've implemented commit and rollback so I use messaging back and forth to pass the new values and I store the old ones.
To do so I copy the objects a a backup variable and then I modify the ones associated via binding to the XAML view, in this way (in theory) any change to the ViewModel data should be reflected.
Also is better because if I commit the changes I just discard the backup variables (this is 90% of the times) and if I need to roll back I copy back from the backup variables.
MainView:
public const string listPropertyName = "list";
private csNodeList _list = new csNodeList();
public csNodeList list
{
get
{
return _list;
}
set
{
Set(listPropertyName, ref _list, value, false);
}
}
Using the message I send back the new values of a node and I put them in the correct position:
private void DoSomething(csMessage message)
{
csMessage rmessage;
if (message != null)
{
switch (message.destination)
{
case csMessage.e2MessageDest.updateNode:
//_editP should be fine.
list.Leaf[list.Leaf.IndexOf(_editP)].Name = ((csLeaf)message.payload).Name;
list.Leaf[list.Leaf.IndexOf(_editP)].Text= ((csLeaf)message.payload).Text;
list.Leaf[list.Leaf.IndexOf(_editP)].Address = ((csLeaf)message.payload).Address;
RaisePropertyChanged(listPropertyName , null, _list, true);
break;
}
}
}
The code is executed correctly and the item is changed.
BUT the RaisePropertyChanged is ignored. I've tried even just the one with the listPropertyName without any change.
If I save the changes exit from the app and get back I see the new value correctly stored
Can you please help me?
Thanks,
Massimo
The reason why your RaisePropertyChanged is ignored is hat yor Leaf class des not implement INotifyOropertyChanged. Commonly the model is wrapped into a view model which then implements INotifyPropertyChanged to notify the view hat something has happened.
However, you also can implement INotifyPropertyChanged on the model class directly. To implement INotifyPropertyChanged each property has to raise the propty changed event.
public string Property {
get { ... }
set {
if (_propertyField == value)
return;
_propertyField = value;
RaisePropertyChanged("Property");
}
}
The code assumes hat there is a method RaisePropertyChanged which actually taises the PropertyChangedEvent.
Thank you everyone for the help.
Investigating your suggestion I've found a slightly different solution; as you correctly said the issue is that the leaf fields are not "observable" so they do not generate a notification event.
I've noticed that if I add or Delete a profile the binding is updated.
So what I've decided to do is not to edit directly the leafs but to replace the node.
What I do not like is that I have to create a node to replace the old one and this allocates a little bit more memory... but for small data like the one I have it can work without any major impact on the app performance/memory foot print.
Here is what I do:
csLeaf _leaf = new slLeaf();
_leaf.Name = ((csLeaf)message.payload).Name;
_leaf.Text= ((csLeaf)message.payload).Text;
_leaf.URL = ((csLeaf)message.payload).Address;
list.Leaf[list.Leaf.IndexOf(_editP)] = _leaf;
To optimized readabilty of code I've enhanced it adding a constructor with 3 parameters so that the code can be:
csLeaf _leaf = new slLeaf(((csLeaf)message.payload).Name, ((csLeaf)message.payload).Text, ((csLeaf)message.payload).Address);
list.Leaf[list.Leaf.IndexOf(_editP)] = _leaf;
The constructor is:
public csLeaf(string _name, string _description, string _address)
{
Name = _name;
Description = _description;
Address = _address;
}
Using a custom activity inside the build template, is there a way to enumerate through the changes made since the previous build?
I plan on eventually compiling a list of changes so when the build is triggered an E-mail is sent displaying information on the build as well as the changes made.
Any information or links would be great.
Thanks
Edit
Would something similar to this work, if I passed the changeset into my custom activity?
public sealed class ChangeSetActivity : CodeActivity
{
// Define an activity input argument of type string
public InArgument<string> Text { get; set; }
public InArgument<IBuildDetail> currentBuild { get; set; }
public InArgument<List<IChangesetSummary>> changes { get; set; }
public OutArgument<string> changeSet { get; set; }
// If your activity returns a value, derive from CodeActivity<TResult>
// and return the value from the Execute method.
protected override void Execute(CodeActivityContext context)
{
// Obtain the runtime value of the Text input argument
string text = context.GetValue(this.Text);
string str = "";
foreach (IChangesetSummary c in changes.Get(context))
{
str = string.Format("User - {0} Comment - {1}", c.CheckedInBy, c.Comment);
}
context.SetValue<string>(this.changeSet, str);
}
}
Obviously this is very basic stuff at the minute, just to get it working.
