Android: when tapping on load on demand template the data is not loaded. 

If you use the LoadOnDemandCommand you can bind the command to the button inside the template.


On WinUI there is an exception runtime



Use automatic load on demand mode or bind the command to the template

Expose command that executes when checkbox state changes.

Currently I am using EventToCommandBehavior:

        <telerik:RadCheckBox x:Name="checkbox" IsCheckedChanged="checkbox_IsCheckedChanged">
                <telerik:RadEventToCommandBehavior EventName="IsCheckedChanged" Command="{Binding CheckedCommand}" />

public class ViewModel : NotifyPropertyChangedBase
    public ViewModel()
        this.CheckedCommand = new Command<IsCheckedChangedEventArgs>(this.CheckBoxUserCommand);

    private void CheckBoxUserCommand(IsCheckedChangedEventArgs obj)
        // logic here:

    public ICommand CheckedCommand { get; set; }

When setting IsEnabled through binding, it does not work on items level, it works on toolbar level. Still the Isvisible property works on items level. 

<telerik:RadToolbar x:Name="toolbar" >
    <telerik:ToggleButtonToolbarItem Text="ToggleButton" IsEnabled="{Binding IsActive, Mode=TwoWay}">
            <FontImageSource Glyph="{x:Static telerik:TelerikFont.IconBold}"
                        FontFamily="{x:Static telerik:TelerikFont.Name}"
                        Size="16" />

Regardless of the RadEntry's BackgroundColor property, I've noticed the visible-background-color to differ when the RadEntry receives active focus.

The observed behavior is this:

  • RadEntry's visible-background-color generally equals RadEntry's BackgroundColor property
  • RadEntry's visible-background-color changes to gray when hovered regardless of day-night mode
  • RadEntry's visible-background-color changes to white when focused
  • RadEntry's visible-background-color restores to RadEntry's BackgroundColor when unfocused

Typically, in day mode settings (Windows default), the RadEntry's BackgroundColor == white so you don't see the problem. However, in night mode settings (Android default), we want the RadEntry's BackgroundColor == black so the problem is more prevalent since you're typing white text on a white background.

When using Visual States, and, if you try to re-enforce the same BackgroundColor property in all of the visual states, sometimes focus, hover, unfocus, hover, focus sequence will allow you to edit in the RadEntry in your desired RadEntry's BackgroundColor property instead of white, but, most of the time is white.

This problem can be reproduced on Windows and Android if you set your application to night mode Application.Current.UserAppTheme = AppTheme.Dark and set RadEntry's BackgroundColor=Black and TextColor=White in XAML. Put 2 or 3 RadEntry's on the page so you can navigate between them to see the problem.

The CheckBox renders a small checkmark when IsAnimated="False" but normal size if IsAnimated="True" on Windows. It's quite noticeable if If you scale up the Length to say 40, the checkbox scales up but the checkmark doesn't scale, leaving it weird looking.

Provide support for nested properties with null values. 

Currently when using the following scenario: null ref exception is throw, when manager is null:

private Person _manager;
public Person Manager
    get { return _manager; }
    set { UpdateValue(ref _manager, value); }

<telerik:DataGridTextColumn PropertyName="Manager.Name" 


Provide support for null values when nested properties are used in datagrid columns.

A control that would read a QR code and return a string would make me buy this. I am currently using an ASP.NET Telerik Forms Site with instascan.js to read a QR code using a mobile camera, call an API endpoint, and display an alert (the heavy lifting is done on the server in the API). A simple QR scanner would be really useful in a mobile app "out of the box" unless you can suggest a free/low cost component I can plug into a solution based on the new MAUI platform from Telerik?
