Change Telerik Windows 8 Theme for RadWindow Style-1 in Silverlight


Introduction

In this article we will see how to change the default RadWindow theme from Telerik in Silverlight. In this example we would modify the Windows 8 theme for the RadWindow control.

Before and After

Here’s how before and after view of the RadWIndow would look like in Telerik’s Windows 8 theme.

Things you need

Before you start doing it, here are the things you need to have.

  1. Telerik Silverlight Theme Source
  2. Microsoft Expression Blend + Sketchflow Preview for Visual Studio 2012 (Optional if you are good in XAML)

Style Location

Make sure you are choosing the Windows 8 theme.

The RadWindow style for Telerik Windows 8 theme is located in “Telerik.Windows.Controls.Navigation.xaml”

Search for “RadWindowStyle” in the xaml which should be of type “telerikNavigation:RadWindow” and you would be navigated to the style location.

The Template for RadWindow would be in a ControlTemplate with key as “RadWindowTemplate”. Here is the location where you could change the style.

Modifying the Style

As per the image, we would be having Rounded Corners in the RadWindow. The following xaml for the control template would help you understand the design.
