RadWindowInteropHelper
The RadWindowInteropHelper helper class assists for the interoperation between Windows Presentation Foundation (WPF) and Win32 code.
Here is a brief list of all attached properties exposed by the class:
- ClipMaskCornerRadius: The CornerRadius used to create a clipping mask on the underlying Window.
- AllowTransparency: Gets or sets the AllowTransparency property of the underlying Window.
- OpaqueWindowBackground: The Brush used to render the Background of the underlying window if AllowTransparency is set to False.
- Title: Gets or sets the Title used to display in the OS for the underlying Window.
- Icon: Gets or sets the ImageSource used to display the Icon in the OS for the underlying Window.
- ShowInTaskbar: Gets or sets the ShowInTaskbar property of the underlying Window.
Example 1 demonstrates how to set each of the properties both in XAML and code-behind while Figure 1 and Figure 2 illustrate the final result.

Example 1: Set RadWindowInteropHelper attached properties
RadWindowInteropHelper.SetClipMaskCornerRadius(this, new CornerRadius(0));
RadWindowInteropHelper.SetAllowTransparency(this, false);
RadWindowInteropHelper.SetOpaqueWindowBackground(this, Brushes.Red);
RadWindowInteropHelper.SetTitle(this, "Custom Window");
RadWindowInteropHelper.SetIcon(this, new BitmapImage(new Uri("../../icon.png", UriKind.RelativeOrAbsolute)));
RadWindowInteropHelper.SetShowInTaskbar(this, true);
RadWindowInteropHelper.SetClipMaskCornerRadius(Me, New CornerRadius(0))
RadWindowInteropHelper.SetAllowTransparency(Me, False)
RadWindowInteropHelper.SetOpaqueWindowBackground(Me, Brushes.Red)
RadWindowInteropHelper.SetTitle(Me, "Custom Window")
RadWindowInteropHelper.SetIcon(Me, New BitmapImage(New Uri("../../icon.png", UriKind.RelativeOrAbsolute)))
RadWindowInteropHelper.SetShowInTaskbar(Me, True)
