How to Use RadWindow as MainWindow.

Solution

1. First open the MainWindow.xaml file and replace the Window declaration with a RadWindow declaration:

XAML

	  <telerik:RadWindow x:Class="RadWindowAsMainWindow.MainWindow"
		  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
		  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
		  xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
		  Header="MainWindow" Height="350" Width="525">
	  ...
	  </telerik:RadWindow>

and in code-behind:

C#

	public partial class MainWindow : RadWindow
	{
	}

2. Remove StartupUri from the Application definition inside App.xaml:

XAML

  <Application x:Class="RadWindowAsMainWindow.App"
	  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
	  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
  ...

3. Then override the OnStartup method of the Application class to show the RadWindow:

C#

  public partial class App : Application
  {
	  protected override void OnStartup(StartupEventArgs e)
	  {
	  new MainWindow().Show();
	  base.OnStartup(e);
	  }
  }
