Release Release 2.0.0

Hi Team,

You can replicate this behavior with the following code in a preview14 MAUI project with Telerik UI for MAUI v0.6.0.


  • All other UI for MAUI prerequisites have been met, as this work when being defined in XAML instead.
  • I have tested other page elements for the PlacementTarget, like this.Content and RootGrid, same exception.
  • I am deploying to Windows, so I am not sure if this happens in iOS/Android/MacCatalyst



<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             BackgroundColor="{DynamicResource SecondaryColor}">
    <Grid x:Name="RootGrid">
        <Label Text="Stuff"  />


using Telerik.XamarinForms.Primitives;

namespace MyApp;

public partial class MainPage : ContentPage
    RadPopup popup;
    public MainPage()

        popup = new RadPopup();
        popup.PlacementTarget = this;
        popup.Placement = PlacementMode.Center;

        popup.IsModal = true;
        popup.OutsideBackgroundColor = Color.FromArgb("#FF0000");

        popup.Content = new Label { Text = "Hello Telerik Popup!" };
