Release 11.1.0 (2025 Q3)

When navigating to a page with a RadRichTextEditor, it sometimes pops up an error on page load.  It is inconsistent, but I attached an example gif.  The xaml on the page I'm navigating to is basic:

  <Grid Margin="20">
    <telerik:RadRichTextEditor x:Name="RichTextEditorControl"
                               BorderColor="Black"
                               BorderThickness="1" />
  </Grid>

 

I believe this problem started with MAUI version 9.0.70.  Possibly with one of these changes:

https://github.com/dotnet/maui/pull/28354/files

In code-behind or view model I would like to execute a particular procedure for a CellTap event. Your SDK examples do not seem to include any such example. How do I achieve this?

Hi,

I think is bug :

<telerikInput:RadEntry x:Name="txtName" WatermarkText="User Name" HorizontalOptions="Center" VerticalOptions="Center" WidthRequest="200"   Text="test"/>

In this case you do not see the Text property value "test".

Thanks,

I have a form with a RadDataGrid on it.

I am trying to bind it's itemssource with the following code:

var products = JsonSerializer.Deserialize<List<Product>>(response);
dataGrid.ItemsSource = products;

No data is showing up in the grid.

If I set the value in the Constructor of the form (like in the demo code provided it binds fine.)

private void OnCounterClicked(object sender, EventArgs e)
{

      try
      {
          var criteria = txtSearchBox.Text;
          var response = client.DownloadString($@"http://rebelscum/apiswise/product/search?searchCriteria={criteria}");
       
          var products = JsonSerializer.Deserialize<List<Product>>(response);
          dataGrid.ItemsSource = products;
       
        }
        catch (Exception ex)
      {
       
          var x = 1;
      }

 

    <telerikDataGrid:RadDataGrid x:Name="dataGrid" Grid.Row="3" AutoGenerateColumns="False" >
                <telerikDataGrid:RadDataGrid.Columns>
                    <telerikDataGrid:DataGridTextColumn PropertyName="id"

I'm running a new preview installation of Visual Studio Preview (latest) as recommended by the docs. When trying to run the CryptoTracker example for the first time, I receive this error. I'm trying to run this on an iOS simulator that connected without any issues while pairing. Any help would be appreciated :)

Hello,

We are looking to port an existing Xamarin Forms app to MAUI. Can you please confirm that the RadAutoComplete control will be available? e.g.

<ContentPage
    xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    xmlns:telerikInput="clr-namespace:Telerik.XamarinForms.Input;assembly=Telerik.Maui.Controls.Compatibility">

       <telerikInput:RadAutoComplete />

Thanks.

Release 5.0.0

A number of RadDataGrid properties can be successfully set in App.xaml, but setting others causes the control to display nothing -- at least in Android.

While I have not tested all possible settings, these results were found experimentally:

Can be used: BackgroundColor, DataOperationIndicatorMode, GridLinesThickness, HorizontalOptions, LoadOnDemandMode, Margin, MinimumHeightRequest, SelectionMode, UserSortMode, VerticalOptions, and ViewportBufferHeight.

Cannot be used in App.Xaml style: AutoGenerateColumns, GridLinesColor, GridLinesVisibility, LoadOnDemandBufferItemsCount, RowHeight, and SelectionUnit.

Telerik controls are heavily dependent on stylings and templates, but documentation (especially MAUI) still heavily favors XAML despite much code is now being written exclusively in C#. I have already spent many hours on failed attempts to code these things in C# that could have been so easily avoided if C# examples were also included. For instance, I have just about given up on how in the world to display alternate strings for a MAUI DataGridBooleanColumn and I am certainly not going to publish an app where the only possible display strings are the two supplied defaults.

After updating VS2022 Preview to the April 12 Release, at least 3 Telerik Renderers are no longer supported for Android: EntryRenderer, EntryRendererBase, and LegendRenderer. Error in all cases is implementation of Android.Runtime.IJavaObject fails to inherit Java.Lang.Object or Java.Lang.Throwable.

Update Visual Studio 2022 Preview to 17.3.0 Preview 1.0.

Create a new MAUI application using the "Telerik .NET MAUI App (Preview) (Progress). (Attached).

Build the application (test done targeting "Windows Machine"; net6.0-windows10.0.19041.

Two errors will appear in the Error List window:

Severity Code Description Project File Line Suppression State
Error PRI175: 0x80073b0f - Processing Resources failed with error: Duplicate Entry. TelerikMauiApp2 <FullPathOmitted>\TelerikMauiApp2\WINAPPSDKGENERATEPROJECTPRIFILE 1
Error PRI222: 0x80073b0f - Unspecified error occurred. TelerikMauiApp2 <FullPathOmitted>\TelerikMauiApp2\WINAPPSDKGENERATEPROJECTPRIFILE 1

These errors are typically seen when some component is not at the same version as the framework. In this case, Telerik UI for .NET MAUI 0.8.0 targets RC2 according to the release notes.

When focusing on combobox either by clicking on combobox or through tab focus it open the dropdown but many time it happens that the dropdown keeps blinking which makes it impossible to select any item from the dropdown. And due to very rapid show and hide of the dropdown it does not let choose any other control on the page and makes the entire page unusable.

    <VerticalStackLayout>
        <Label 
            Text="Welcome to .NET MAUI!"
            VerticalOptions="Center" 
            HorizontalOptions="Center" />
        <Label Text="Status:" />
        <telerik:RadComboBox/>

    </VerticalStackLayout>

This works for Android. IOS gives error "Cannot resolve type "http://schemas.telerik.com/2022/xaml/maui:telerik:RadComboBox

But  telerik:RadCheckBox does not have the same problem.

   <VerticalStackLayout>
        <Label 
            Text="Welcome to .NET MAUI!"
            VerticalOptions="Center" 
            HorizontalOptions="Center" />
        <Label Text="Status:" />
        <telerik:RadCheckBox IsChecked="True"/>

    </VerticalStackLayout>     

Will work for IOS and Android.

How do I fix this?

I am using VS Community 2022 Preview 

Version 17.3.0 Preview 6.0

and Telerik.UI.for.Maui.Trial 2.2.0
