I would like to replace a string into Razor view and for some reason it does not work
#foreach (var item in Model)
{
<tr>
<td>#Html.DisplayFor(modelItem => item.User)</td>
<td>#Html.DisplayFor(modelItem => item.PasswordExpired.Replace("True", "Yes"))</td>
</tr>
}
Property PasswordExpired is a bool.
Any help would be appreciated.
It works nice with this code
#foreach (var item in Model)
{
<tr>
<td nowrap="">#Html.DisplayFor(modelItem => item.User)</td>
#{
if (item.PasswordExpired != null)
{
string isPasswordExpired = item.PasswordExpired.Replace("True", "Yes").Replace("False", "No");
<td>#isPasswordExpired</td>
}
else
{
string isPasswordExpired = "";
<td>#isPasswordExpired</td>
}
}
</tr>
}

I am new to MVC and now stuck in a serious problem. it is for me, very serious
I need to load a view with a list of meetings (which is loading fine) in html , I have added a checkbox to each row also. Now I need to save to the database ,only the checked values. But the controller is returning null when posting.. Really stuck and cant find a solution.
Pls see code below which I have done
Model
public class aMeet
{
public List<AcceptedRecords> amList { get; set; }
public static List<AcceptedRecords> GetamList()
{
DataSet ds = new DataSet();
List<AcceptedRecords> resultlist = new List<AcceptedRecords>();
using (cmd)
{
cmd.CommandText = #"SELECT Line_code,person_code,person_address from tbl where meeting_code =859489;
ds = cmd.ExecuteDataSet();
}
if (!Utils.IsDataSetEmpty(ds))
{
AcceptedRecords tpmApp;
foreach (DataRow row in ds.Tables[0].Rows)
{
tpmApp = new AcceptedRecords();
tpmApp = tpmApp.LoadRecords(row);
resultlist.Add(tpmApp);
}
}
return resultlist;
}
}
Model
public class AcceptedRecords
{
public int line_Code { get; set; }
public string person_Name { get; set; }
public string person_Address { get; set; }
public bool extra_checked { get; set; }
}
View
#model projct.Models.aRecs
#using (Html.BeginForm("AddRecord","Home"))
{
<table id="tbl" style ="width:100%" cellpadding="0" cellspacing="0" class="race-fields">
<thead>
<tr>
<th style="width:500px">line code</th>
<th style="width:100px">name</th>
<th style="width:500px">address</th>
<th style="width:500px">extra</th>
</tr>
</thead>
<tbody>
<tr>
#for (int i = 0; i < Model.amList.Count; i++)
{
<tr class="EvenRow">
<td>
#Html.DisplayFor(m => m.amList[i].line_Code) </td>
<td>#Html.DisplayFor(m => m.amList[i].person_name) </td>
<td>#Html.DisplayFor(m => m.amList[i].person_address) </td>
<td>
#Html.CheckBoxFor(m => m.amList[i].extra_checked) </td>
</tr>
}
</tr>
<tr>
<span>
<input type="submit" Value ="Save"/>
</span>
</tr>
</tbody>
</table>
}
Controller
[HttpPost]
public ActionResult AddRecord(List<aMeet> spm)
{
if (spm == null)
throw new ApplicationException("No Parameters passed to Create");
int? appID = 0;
return Json(appID);
}
}
--- It Is triggering to controller on Save but model [spm] is null.
How to get this corrected. Here I need to save to database the tr elements that are checked. Please request any help. I have tried a lot of things but the model is always null/
Many thanks
Assuming your aRecs class has a amList property which is a list of AcceptedRecords
public class aRecs
{
public List<AcceptedRecords> amList { set; get; }
}
Assuming line_code value is a unique (may be primary key) to get a record from your corresponding table, In your view, you need to keep the line_code property value of each item in amList in a hidden field so that when the form is submitted you will get this value and using that you can query the corresponding record and update it.
#model YourNamespaceHere.aRecs
#using (Html.BeginForm("AddRecord","Home"))
{
<table>
#for (int i = 0; i < Model.amList.Count; i++)
{
<tr class="EvenRow">
<td>
#Html.DisplayFor(m => m.amList[i].line_Code)
</td>
<td>#Html.DisplayFor(m => m.amList[i].person_Name) </td>
<td>
#Html.CheckBoxFor(m=>m.amList[i].extra_checked)
#Html.HiddenFor(m => m.amList[i].line_Code)
</td>
</tr>
}
</table>
<input type="submit"/>
}
And in your HttpPost action, your parameter will be a single object of aRecs
[HttpPost]
public ActionResult AddRecord(aRecs model)
{
foreach (var item in model.amList)
{
var lineCode = item.line_Code;
var isChecked = item.extra_checked;
/// get the record using lineCode and update the record.
}
return RedirectToAction("Index");
}
Depending on my record, I'd like to change the style of the table row in my current iteration.
The below example doesn't work, but how would I go about doing this correctly?
foreach (var item in Model)
{
#{
if (item.DataState != DataState.Active)
{
<tr style="background-color: red">
}
else
<tr>
}
<td>#item.Name</td>
</tr>
}
So effectively, I'd like to dynamically render the <tr> element differently based on the DataState of my model.
Here's a shorter approach:
#foreach (var item in Model)
{
<tr #(item.DataState != DataState.Active ? "style=background-color:red" : "")>
<td>#item.Name</td>
</tr>
}
Edit: Code fixed
There are multiple way you can write condition.
Option 1:
#foreach (var item in Model)
{
if (item.DataState != DataState.Active)
{
<tr style="background-color: red">
<td>#item.Name</td>
</tr>
}
else
{
<tr>
<td>#item.Name</td>
</tr>
}
}
Option 2:
#foreach (var item in Model)
{
<tr style="#( item.DataState != DataState.Active ? "background-color: red;" : "" )">
<td>#item.Name</td>
</tr>
}
Define the attributes in a variable. The razor parser will omit the attribute if its value is null
#foreach (var item in Model)
{
var attributes = item.DataState == DataState.Active ? null : "background-color: red";
<tr style=#attributes>
<td>#item.Name</td>
</tr>
}
Not sure what kind of error you faces right now, but i gess your problem is that Razor don't understand all cases of tricky html render.
You can force him to render html where you need with #: symbol for single string or <text> tag like this:
#foreach (var item in Model)
{
if (item.DataState != DataState.Active)
{
#: <tr style="background-color: red">
}
else
{
<text><tr></text>
}
<td>#item.Name</td>
</tr>
}
You're probably going to get compile errors if you start splitting the <tr> tag up in the view and I'd not duplicate large chunks of code. I would do the following:
#foreach(var item in Model) {
string strStyle=String.Empty;
if(item.DataState!=DataState.Active) { strStyle = "background-color:red;" }
<text>
<tr style="#strStyle">
<td>#item.Name</td>
</tr>
</text>
}
#(item.DataState != DataState.Active ? "style=" + "background-color:red" : "")
#(!string.IsNullOrWhiteSpace(Model?.District?.Name) ? Html.Raw($"<span class=\"location\">{Model?.District?.Name}</span>") : string.Empty)
I am getting the following error
The model item passed into the dictionary is of type 'System.Collections.Generic.List1[<>f__AnonymousType34[System.String,System.Int32,System.Int32,System.DateTime]]', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable`1[ControllerName]'.
I did the code migration (database update) after that I want to just list the items by column name My code is as follows
public ActionResult Index()
{
DB db = new DB();
var categorylist = from a in db.categories
select new
{
a.CategoryName,
a.ID,
a.stock,
a.EntryDate
};
return View(categorylist.ToList());
}
Any help would be appreciated
Thanks in advance.
View is as follows
#model IEnumerable<Categories.Models.Categories>
#{
ViewBag.Title = "Index";
}
<h2>Index</h2>
<p>
#Html.ActionLink("Create New", "Create") </p> <table class="table">
<tr>
<th>#Html.DisplayNameFor(model => model.CategoryName)</th>
<th>#Html.DisplayNameFor(model => model.stock)</th>
<th>#Html.DisplayNameFor(model => model.EntryDate)</th>
<th></th>
</tr>
#foreach (var item in Model) {
<tr>
<td>#Html.DisplayFor(modelItem => item.CategoryName)</td>
<td>#Html.DisplayFor(modelItem => item.stock)</td>
<td>#Html.DisplayFor(modelItem => item.EntryDate)</td>
<td>
#Html.ActionLink("Edit", "Edit", new { id=item.ID }) |
#Html.ActionLink("Details", "Details", new { id=item.ID }) |
#Html.ActionLink("Delete", "Delete", new { id=item.ID })
</td>
</tr>
}
</table>
To take advantage of the model binding features of MVC you should create a view model which represents those the properties you want to display and/or edit (adjust property types as required)
public class CategoryVM
{
public int ID { get; set; }
public string CategoryName { get; set; }
public int Stock { get; set; }
public DateTime EntryDate { get; set; }
}
and change you method to
public ActionResult Index()
{
DB db = new DB();
var categorylist = (from a in db.categories
select new CategoryVM
{
CategoryName = a.CategoryName,
ID = a.ID,
Stock = a.stock,
EntryDate = a.EntryDate
}).ToList();
return View(categorylist);
}
View
#model List<CategoryVM>
<table>
<thead>
<tr>
<th>Category Name</th>
<th>stock</th>
<th>Entry Date</th>
...
</tr>
</thead>
<tbody>
#foreach(var item in Model)
{
<tr>
<td>#Html.DisplayFor(m => item.ID)<td>
<td>#Html.DisplayFor(m => item.CategoryName)</td>
...
</tr>
}
</tbody>
</table>
I think you need to Change the model type thar you defined in your view
Edit: Try
#model IList<dynamic>
I am newbie and getting the error model item passed into directory is of type system.cllection.generic.list but this directory requires system.collection.ienumerable
Please help me to resolve this error.
I am pasting my controller and view here
Controller
public ActionResult DisplayComment()
{
var result = Manager.GetUsersWhoHaveConsumedFreeCredit();
JavaScriptSerializer serializer = new JavaScriptSerializer();
var callHistory = serializer.Deserialize<List<CallHistory>>(result);
YelloAdminDbContext db = new YelloAdminDbContext();
if (callHistory != null)
{
foreach (var item in callHistory.ToList())
{
int Id = int.Parse(item.Login);
var note = db.Note.OrderByDescending(i => i.Id).Where(i => i.LoginId == Id).FirstOrDefault();
if (note != null && note.LoginId == Id)
{
var temp = note.Comments.ToList();
return PartialView(temp);
}
else
return Content("No Comments");
}
}
return Content("No Comments");
}
View
#model IEnumerable<MyYello.Admin.Models.CallNote>
<table>
<tr>
<th>
#Html.DisplayNameFor(model => model.Comments)
</th>
<th></th>
</tr>
#foreach (var item in Model) {
<tr>
<td>
#Html.DisplayFor(modelItem => item.Comments)
</td>
</tr>
}
</table>
Here you are reuturning List of type Commments:
var temp = note.Comments.ToList();
return PartialView(temp);
while in your view is strongly typed to Model of type IEnumerable<MyYello.Admin.Models.CallNote>
In View you have written, so it conflicts you View is expecting different type while you are passing different type:
#model IEnumerable<MyYello.Admin.Models.CallNote>
you should be returning IEnumerable<MyYello.Admin.Models.CallNote> from your action or if you need to pass Comments type then change in View :
#model List<MyYello.Admin.Models.Comments>
