I have a Forms app using RadPopup

var preview = new RadPopup();
             
preview.IsModal = true;
preview.Placement = PlacementMode.Center;
preview.PlacementTarget = overlay;
 
var containerGrid = new Grid { Padding = 10 };
// populate grid here
 
preview.Content = containerGrid;
 
preview.IsOpen = true;

 

this works great on Android.  On iOS nothing happens.  The popup does not display, and I don't see any errors, exceptions or console messages.

Any suggestions on what might be wrong, or how I can go about debugging this?

Telerik 2019.1.318.1

XF 3.6.0.344457

iOS 12.2

hi,

i need to increase week number font size and weight. that is done using following code, inside CalendarDelegate UpdateVisualsForCell

weekNumberCell.Label.AdjustsFontSizeToFitWidth = true;
weekNumberCell.Style.TextFont = weekNumberCell.Label.Font.WithSize(16);
weekNumberCell.Style.TextFont = UIFont.BoldSystemFontOfSize(16);

 

since week number cell width or label width can not increase, font size automatically get reduce.

i need a way to increase week number cell width or automatically increase according to text in it.

Hi

I have followed the blog post on Using UI for Xamarin in Visual Studio for Mac and successfully added and logged on to the Telerik NuGet source. However I do not see any packages under this source.

Could someone please help

I have a list that is populated when the view is navigating.  Everything loads as expected except with the AutoCompleteView the FilteredItems list starts out empty.  Everything is filtered.  If I enter a character the FilteredItems then shows what I would expect.  With the obsolete AutoComplete this does not occur, the FilteredItems is the complete list as expected.  For now sticking with the correctly behaving AutoComplete

Thanks

hi,

at the end of the "SuggestionItemSelected" event i want to unfocus AutoCompleteView. but use of AutoCompleteView.Unfocus() has no effect on controller, even Unfocused event is not hit. i am doing this because i want to hide Android soft keyboard after user selected suggested item. 

1) At Least  AutoComplete.HideSuggestions(); should hide Android soft keyboard

2) or at the end of SuggestionItemSelected event soft keyboard should hide

i have used Unfocus() event even in "BeginInvokeOnMainThread"

Hide Android soft keyboard is my main concern, only tested in Android.

 

private void AutoComplete_SuggestionItemSelected (object sender, Telerik.XamarinForms.Input.AutoComplete.SuggestionItemSelectedEventArgs e)
       {
         
            
            
               AutoComplete.Text = "";
               AutoComplete.HideSuggestions();
               AutoComplete.Unfocus();
                  
       }

I just upgraded from Windows 10 version 1803 to version 1809 on my development machine, because my Xamarin app was crashing on machines with 1809. Sure enough, after upgrading, Visual Studio would build the app but crash immediately with a XAML Uncaught Exception error and give me no information to go on.

After isolating various bits of code, I found the culprit to be any ContentView with a RadButton in it. If I comment out all of the RadButtons, the code works fine as it did in version 1803 (minus any buttons :-/ ).

Does anybody have any ideas about why this would be happening and/or a workaround other than replacing all my RadButtons?

Hi,

In our chat application we receive Author avatars as byte arrays. I see that in the chat control the Avatar property on Author is a string and it isn't clear how one would use a dynamic image, is there any guidance on achieving this?

thanks

Hi,

We are currently trying to integrate the chat UI with our Xamarin app, and things are going ok however on iOS the rendering of the control looks a little less polished and bits are missing. I have attached an image demonstrating it in this post. I have annotated the image. On Android these issues are not a problem.

The Telerik controls have been installed via the official Nuget package source. We are using the latest version of Xamarin Forms and the Telerik controls.

Questions;

1. How can we improve the iOS rendering?

2. How can we further customise the entry box etc.? I see another post reference a control template, but I can't seem to find the control template XAML anywhere?

many thanks
