2024 Q4 (November) - End of Support for .NET 7
Microsoft discontinued .NET 7 support in May 2024. As of 2024 Q4 (November), we will deprecate .NET 7 distribution. This will give you extra time to transition from .NET 7 to .NET 8.

By upgrading to the most recent version of .NET, you will leverage the latest features, performance enhancements, and security improvements offered by both Microsoft and Telerik. This upgrade will ensure that you can make the most of the cutting-edge advancements provided by both entities.

For more information about the supported .NET versions in .NET MAUI, please review the .NET MAUI Support Policy.

Telerik TabView DataTemplate Problem

Hello, I have an issue in .NET MAUI 8.0 with the TabView control in the following code.

<?xml version="1.0" encoding="utf-8" ?>

                </DataTemplate>
            </telerik:RadTabView.ItemTemplate>

        </telerik:RadTabView>
    </StackLayout>

</ContentPage>

The error I get is: "DataTemplateContent property does not support values of type TabViewItem." Additionally, the tag following the first DataTemplate does not exist.

The version of Telerik I am using is 7.1.0.

NET MAUI 8.0.92 With SDK 8.0.403.1 - RadListView error on iOS 18

Hi,

I've updated to the latest workload and MAUI versions to target iOS 18.

When an item is added to a RadListView I get an application crash which is not recoverable. Please note that I've upgraded Telerik.UI.for.Maui from 7.0.0 to 7.1.0.

 

Below is the error

Objective-C exception thrown.  Name: NSInternalInconsistencyException Reason: Expected dequeued view to be returned to the collection view in preparation for display.

CardActionsListView shows duplicate images for the first time in MAUI WINUI

Hi Team,

I am using CardActionsListView to display the images.

This works fine with Android and IOS, whereas in WINUI when uploaded an image it shows duplicate images, when refreshed the list it shows only one.

 

Can you provide any fix for this.

 

Thanks & Best Regards,

Mohammed Rameez Raza (Rameez)

(iOS) RadRichTextEditor does not update Source in UI

When reloading a page containing RadRichTextEditor and updating the Source, the UI does not reflect the change in iOS only. The Source keeps the value that is assigned in the first page load. On Android, updating the Source after the first page load is properly reflected in the UI.

XAML:

<ContentPage
   ...
   xmlns:telerik="http://schemas.telerik.com/2022/xaml/maui">
   <Grid>
      ...
      <telerik:RadRichTextEditor x:Name="richTextEditor" />
      <telerik:RadRichTextEditorToolbar x:Name="richTextEditorToolbar" RichTextEditor="{x:Reference richTextEditor}" />
      ...
   </Grid>
</ContentPage>
XAML.CS:
protected override void OnAppearing()
{
    base.OnAppearing();
    richTextEditor.Source = _vm.GetHtmlBody();
}

VIEWMODEL:

public string GetHtmlBody()
{
    return Value; // new value is assigned
}

RadSignaturePad throws an unhandled exception

Hi

I start a new Maui project from scratch and use the code from the documentation of the RadSignaturePad (https://docs.telerik.com/devtools/maui/controls/signaturepad/getting-started) but when I build I get a unhandled win32 exception.

If I build on android emulator there is no exception but the signature pad doesn't appear.

Anyone else have problems making the signature pad work?
Thank you
