Hi I'm trying to display a System.Windows.Controls.WebBrowser in a RadWindow. The WebBrowser does not appear to render properly. The WebBrowser control is there (I can right click and display the context menu) but the page it displays is not visible? The following code snippets should demonstrate the issue...
Create the RadWindow in response to a button click...
<Window x:Class="TelerikForm.Window1" 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    xmlns:telerik="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Navigation" 
    Title="Window1" Height="300" Width="300"
    <Grid> 
    <Button Name="launchWindow" Content="launchNewWindow" Click="launchWindow_Click" /> 
  </Grid> 
</Window> 
private void launchWindow_Click(object sender, RoutedEventArgs e) { 
  RadWindow testWindow = new RadWindow(); 
  testWindow.Content = new Browser(); 
  testWindow.Show(); 
And add some content containing the WebBrowser...
<UserControl x:Class="TelerikForm.Browser" 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    Width="600" Height="600"
    <StackPanel> 
    <Border Width="590" Height="590" Margin="5" BorderBrush="Black" BorderThickness="1"
      <WebBrowser Name="browser" Loaded="browser_Loaded" > 
      </WebBrowser>       
    </Border> 
    </StackPanel> 
</UserControl> 
private void browser_Loaded(object sender, System.Windows.RoutedEventArgs e) {       
      browser.Navigate(new Uri("http://www.google.co.uk/", UriKind.RelativeOrAbsolute), nullnull""); 
Thanks in advance..Simon...

Hello Simon,

The RadWindow control doesn't support WebBrowser control as it is displayed into a transparent WPF Window and the WPF Window doesn't support hosting WebBrowser control when it is in transparent mode. What I could suggest you is to use a WPF Window control to host the WebBrowser control.

Hi Simon,

I just want to add that there is a work-around for this limitation now - you just need to set the AllowTransparency attached property of the RadWindow control to false. Here is an example how to do this:
var window = new RadWindow
{
    Content = new WebBrowser { Source = new Uri("http://www.telerik.com/") },
    Width = 700,
    Height = 500
};
RadWindowInteropHelper.SetAllowTransparency(window, false);
window.Show();
