Telerik UI for Windows Phone by Progress

The RadWindow control allows you to apply offsets to its placement. You are able to apply a vertical and horizontal offsets via the VerticalOffset and HorizontalOffset properties. Two offsets are applied respectively on the top and on the left side.

The offsets doesn't get applied when the window is in Fullscreen mode.

Here is an example.

      <telerikPrimitives:RadWindow x:Name="radWindow" IsFullScreen="False" Placement="TopLeft" PlacementTarget="{Binding
ElementName=LayoutRoot}" WindowSizeMode="AutoSize" HorizontalOffset="20" VerticalOffset="20"></telerikPrimitives:RadWindow>

Here is a snapshot of the result.
