absolute beginner with xamarin.
Followed the following tutorial to try and simply click a button to display the contact list, select a contact, and then to display firstname, surname, and address on the screen.
https://github.com/xamarin/recipes/tree/master/Recipes/ios/shared_resources/contacts/choose_a_contact
Managed to get the firstname and surname to be displayed, but cannot get the address. Constantly getting the error
Foundation.MonoTouchException: Objective-C exception thrown. Name: CNPropertyNotFetchedException Reason: A property was not requested when contact was fetched.
On the
contanct.PostalAddresses
This is the snippet of code:-
partial void UIButton197_TouchUpInside(UIButton sender)
{
// Create a new picker
var picker = new CNContactPickerViewController();
// Select property to pick
picker.DisplayedPropertyKeys = new NSString[] { CNContactKey.GivenName, CNContactKey.FamilyName, CNContactKey.PostalAddresses };
// Respond to selection
var pickerDelegate = new ContactPickerDelegate();
picker.Delegate = pickerDelegate;
pickerDelegate.SelectionCanceled += () => {
SelectedContact1.Text = "";
};
pickerDelegate.ContactSelected += (contact) => {
SelectedContact1.Text = contact.GivenName;
SelectedContact2.Text = contact.FamilyName;
SelectedContact3.Text = contact.PostalAddresses
};
pickerDelegate.ContactPropertySelected += (property) => {
SelectedContact1.Text = property.Value.ToString();
};
// Display picker
PresentViewController(picker, true, null);
}
Am i missing something?
Seem to have resolved this if anyone else is having a similar issue.
The solution was to completely close down visual studio on the mac and re-open it.
Originally, i was stopping the project, and re-building. Possibly a bug, but non of my changes where being picked up.
A simple re-start kicked it back in

I have the following code within a script tag on my razor view:
self.regions = [];
#foreach(var region in Model.OperationRegions)
{
<text>
self.regions.push({
regionid: '#region.Region_Id',
regionname: '#region.Title',
selected: ko.observable(#(Model.RegionsList.Contains(region.Region_Id).ToString().ToLower()))
});
</text>
}
self.categories = [];
#foreach(var category in Model.Categories)
{
<text>
self.categories.push({
categoryid: '#category.Category_Id',
title: '#category.Title'
});
</text>
}
For clarity, the code outside of the foreach loops and within the text tags are Javascript and the purpose of the razor code is to populate my Javascript arrays with data from the server.
When I run this I am currently getting a server error saying "CS0162: Warning as Error: Unreachable code detected"
The error is thrown on the second "foreach" in the snippet.
Surprisingly I couldn't find another question referring to this error message on an MVC razor page so I'm posting this here.
My question is why is that line of code considered to be unreachable? I will update this question if I find anything else on my page to be relevant to the issue as I try to debug.
The error has disappeared now. I had renamed a property of my model and not recompiled before trying to load the page again. Recompiling made the error go away. I have no idea how the root cause translated to the error message shown but its fixed now in any case.
This is an extremely poor way to handle this. There's no need to build an array piece by piece like this. Just convert your list to JSON.
self.regions = #Html.Raw(Json.Encode(Model.OperationRegions.Select(region => new {
regionid = region.Region_Id,
regionname = region.Title,
selected = Model.RegionsList.Contains(region.Region_Id)
})));
The only thing this can't handle is making selected an observable. However, you can simply loop through the array and fix this:
for (var i = 0; i < self.regions.length; i++) {
self.regions[i].selected = ko.observable(self.regions[i].selected);
}
However, the better approach is to use another view model:
var OperationRegionViewModel = function (data) {
var self = {};
self.regionid = ko.observable(data.regionid);
self.regionname = ko.observable(data.regionname);
self.selected = ko.observable(data.selected);
return self;
};
Then, you can just do something like:
var regions = #Html.Raw(Json.Encode(Model.OperationRegions.Select(region => new {
regionid = region.Region_Id,
regionname = region.Title,
selected = Model.RegionsList.Contains(region.Region_Id)
})));
self.regions = $.map(regions, new OperationRegionViewModel);
Or, even better build your JSON all at once:
var json = #Html.Raw(Json.Encode(new {
regions = Model.OperationRegions.Select(r => new { ... }),
categories = Model.Categories.Select(c => new { ... }),
// etc
});
Then, inject this all into your view model:
var viewModel = (function (json) {
// other stuff
self.regions = $.map(json.regions, new OperationRegionViewModel);
self.categories = $.map(json.categories, new CategoryViewModel);
// etc
})(json);
This question is for Android. StyleIds have been set for images. Per the documentation, these StyleIds should appear as labels in Android. But they do not.
I have verified that the following exists -
Xamarin.Forms.Forms.ViewInitialized += (object sender, Xamarin.Forms.ViewInitializedEventArgs e) =>
{
if (!string.IsNullOrWhiteSpace(e.View.StyleId))
{
e.NativeView.ContentDescription = e.View.StyleId;
}
};
I am new to Xamarin UItests and have to solve this as the first thing. Has anyone encountered this before?
You could switch over to using AutomationId, it was introduced to Xamarin.Forms in version 2.2 (release notes)
The AutomationId property isn't used by Xamarin.Forms so it doesn't affect any functionality to use it as a unique identifier for testing.
Below is a sample using AutomationId on an image, along with a screenshot of a Repl Tree output. (Click here to read more about AutomationId)
public App()
{
// The root page of your application
var content = new ContentPage
{
Title = "XamarinUITest_Images",
Content = new StackLayout
{
VerticalOptions = LayoutOptions.Center,
Children = {
new Label {
HorizontalTextAlignment = TextAlignment.Center,
Text = "Welcome to Xamarin Forms!"
},
new Image {
Source = "circle1",
StyleId = "myStyleID",
AutomationId = "myAutomationID"
}
}
}
};
MainPage = new NavigationPage(content);
}
How we can show "No Data Available" message in RDLC Reports via Resources files if no data is found. Currently we are reflecting message from NoRowsMessage property for a table, matrix, or list
(https://technet.microsoft.com/en-us/library/cc645968.aspx).
But we want to show it via Resource files and C# code rather then setting it from Properties of Table. Can anyone please assist. The code (Page_Load) of our control page (.ascx)is mentioned below:
private void Page_Load(object sender, EventArgs e)
{
var presenter = (ReportPresenter)Model;
reportViewer.ProcessingMode = ProcessingMode.Local;
reportViewer.Visible = true;
var rdlcPath = "~/ReportsRDLC/EmployeeData.rdlc";
if(presenter.ReportFilter.GroupOption == Resources.Date)
{
rdlcPath = "~/ReportsRDLC/EmployeeDatebyDate.rdlc";
}
groupOption.SelectedValue = presenter.ReportFilter.GroupOption;
const string DataSetName = "EmployeeDataSet";
reportViewer.LocalReport.ReportPath = HttpContext.Current.Server.MapPath(rdlcPath);
var dataSource = new ReportDataSource(DataSetName, presenter.EmployeeDetails);
reportViewer.AsyncRendering = false;
reportViewer.SizeToReportContent = true;
reportViewer.ShowPrintButton = false;
reportViewer.ShowRefreshButton = false;
reportViewer.ShowToolBar = true;
reportViewer.Height = 600;
reportViewer.Width = 400;
reportViewer.ShowPageNavigationControls = false;
reportViewer.ShowFindControls = false;
reportViewer.ShowZoomControl = false;
reportViewer.LocalReport.DataSources.Add(dataSource);
}
Perhaps you could send the message as a parameter.
You can tell if the report will be empty depending if presenter.EmployeeDetails is empty.
ReportParameter[] myParameters = new ReportParameter[1];
myParameters[0] = new ReportParameter("pEmptyMessage", presenter.EmployeeDetails.Any() ? "No Data Available" : string.Empty);
reportViewer.LocalReport.SetParameters(myParameters);
On your report you can then display this message as you please, using the parameter. You can even place it in a textbox and decide whether to display it based on the value.
I hope this is of use to you.
Edit: I forgot to mention that you should add the report parameter with the correct name to your reporter:
In the reporter you can then use the parameter as followed : [#pEmptyMessage]
=Parameters!pEmptyMessage.Value
I am trying to add a list in a VerticalFieldManager and then that manager to another VerticalFieldManager. I am using it in custom tabs.First time when application starts it runs fine but when I switch to another tab and return to same it gives IllegalStateException.
I tried it in many ways but not getting what is causing the exception in adding that VerticalFieldManager.
I am using the code :
//HEADER
_bitmap = EncodedImage.getEncodedImageResource("Friends.png");
friendsBmp = new BitmapField(Constants.sizePic(_bitmap, _bitmap.getHeight(), _bitmap.getWidth()));
//add(WebBitmapField.getUrlHFM());
SCREEN_FLAG = Constants.FRIENDS_FLAG ;
//FRIENDS' UPPER TAB
friendsTabHFM =new HorizontalFieldManager();
Bitmap ConnectedUser_normal_Bmp =Constants.sizePic(EncodedImage.
getEncodedImageResource("connected_user_normal.png"),40, Display.getWidth()/2); //Bitmap.getBitmapResource("connected_user_normal.png");
Bitmap search_normal_Bmp = Constants.sizePic(EncodedImage.
getEncodedImageResource("search_normal.png"),40, Display.getWidth()/2);//Bitmap.getBitmapResource("search_normal.png");
Bitmap ConnectedUser_tap_Bmp = Constants.sizePic(EncodedImage.
getEncodedImageResource("connected_user_tap.png"),40, Display.getWidth()/2);//Bitmap.getBitmapResource("connected_user_tap.png");
Bitmap search_tap_Bmp = Constants.sizePic(EncodedImage.
getEncodedImageResource("search_tap.png"),40, Display.getWidth()/2);//Bitmap.getBitmapResource("search_tap.png");
connectedUsersTab= new CustomButtonField(ConnectedUser_normal_Bmp.getWidth(), "", ConnectedUser_normal_Bmp, ConnectedUser_tap_Bmp, ButtonField.FIELD_HCENTER );
connectedUsersTab.setChangeListener(this);
searchTab = new CustomButtonField(search_normal_Bmp.getWidth(), "", search_normal_Bmp, search_tap_Bmp, ButtonField.FIELD_RIGHT);
searchTab.setChangeListener(this);
friendsTabHFM.add(connectedUsersTab);
friendsTabHFM.add(searchTab);
if(Constants.isGetConnectedFriends){
Constants.isGetConnectedFriends =false ;
if(friendsVFM.getFieldCount()!= 0){
friendsVFM.deleteAll();
}
//GET CONNECTED FRIENDS WEB SERVICE CALL
GetConnectedFriendsInterMediater getConnectedFriendsInterMediater = new GetConnectedFriendsInterMediater(WebServiceDetails.METHOD_GET_CONNECTED_USER, Jxa.loginUserName);
PleaseWaitPopupScreen.showScreenAndWait(getConnectedFriendsInterMediater, Constants.PLEASE_WAIT_TEXT);
}else if(Constants.isGetUserByUsername){
//Constants.isGetUserByUsername = false ;
GetUserByUsernameIntermediator getUserListIntermediator=new GetUserByUsernameIntermediator(Jxa.loginUserName ,SearchUserScreen.userName);
PleaseWaitPopupScreen.showScreenAndWait(getUserListIntermediator, Constants.PLEASE_WAIT_TEXT);
}else if(Constants.isGetAllUser){
Constants.isGetAllUser = false ;
GetAllUserListIntermediator getAllUserListIntermediator=new GetAllUserListIntermediator(WebServiceDetails.METHOD_FIND_USERS,SearchUserScreen._ageRange,SearchUserScreen._status,SearchUserScreen._religion,String.valueOf(SearchUserScreen._page) ,Jxa.loginUserName);
PleaseWaitPopupScreen.showScreenAndWait(getAllUserListIntermediator, Constants.PLEASE_WAIT_TEXT);
}
if(_mainScreenVFM.getFieldCount()!=0){
_mainScreenVFM.deleteAll();
}
_mainScreenVFM.add(friendsTabHFM);
_mainScreenVFM.add(friendsVFM);
These code is for a tab in which two sub-tabs are there.For sub tabs it is running fine but for not for main tab.
One more scenario is there,when GetConnectedFriendsInterMediater is called in that I am adding the list in friendsVFM which creating the exception.
Code for that is:
GetConnectedFriendsWebService getFriendsWebService = new GetConnectedFriendsWebService(method ,userName);
Vector friendsVecList= getFriendsWebService.getFriends();
Constants.connectedUsersVector = friendsVecList ;
synchronized (UiApplication.getEventLock()) {
if(TabControlScreen.friendsVFM.getFieldCount()!=0){
TabControlScreen.friendsVFM.deleteAll();
}
TabControlScreen.friendsVFM.add(ConnectedFriends.getInstance(KingdomConnectMain.buddyList)); //HERE LIST IS ADDED
}
I have resolved the problem ,when I was switching the tab ,I was not creating new instance for friendsVFM and using the same instance which was causing the exception at that time.Now ,same exception is thrown when I am trying to add buddyList in _listVFM . I know it is due to adding the buddyList again which is already added.Is there any solution so that I can add the list without exception. Code for that:
//CREATING SINGLETON REFERENCE OF THE BUDDYLIST SCREEN
public static ConnectedFriends getInstance(BuddyListField buddyListField){
if(connectedFriends==null){
connectedFriends = new ConnectedFriends(buddyListField);
}
return connectedFriends;
}
public ConnectedFriends(BuddyListField buddyListField) {
if(_listVFM!=null){
_listVFM.deleteAll();
}
_listVFM = new VerticalFieldManager();
_listVFM.add(buddyListField);//HERE IS EXCEPTION ,BUT WANT TO ADD THE LIST //SECOND TIME TOO
}
When I am returning from another tab to sam tab it throws exception or in other words I am not able to add the list.
Illegal state exception occurs when you're trying to add fields twice as suggested by Signare also. I guess you should try this first:
friendsVFM.getManager().delete(friendsVFM);
I solved it by using getManager() on buddyList and removing that.Than again I added it as per requirement and it worked.Code for this :
if(ConnectedFriends.getInstance(KingdomConnectMain.buddyList).getManager()!= null){
ConnectedFriends.getInstance(KingdomConnectMain.buddyList).getManager().delete(ConnectedFriends.getInstance(KingdomConnectMain.buddyList));
}
TabControlScreen.friendsVFM.add(ConnectedFriends.getInstance(KingdomConnectMain.buddyList));
This code is used while calling GetConnectedFriendsWebService in the second part of codes.
If I type a phone number into the phone application on my Blackberry (5.0.0) I can hit the menu button, and one of the options is "Add to contacts" which will bring up the add contact screen, with the phone number already populated. I would like to do the same thing in my app - bring up the 'add to contacts' screen and pre-fill it with a particular phone number. Is this possible on the BlackBerry 5.0 OS?
While browsing for more information on BlackBerry contacts, I came across this support forum question, which answers my question indirectly. Posted here for anyone else in a similar situation:
