Things you need
Before you start doing it, here are the things you need to have.
- Telerik Silverlight Theme Source
- 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 RadButton style for Telerik Windows 8 theme is located in “Telerik.Windows.Controls.xaml“
Search for “RadButtonStyle” in the xaml which should be of type “telerik:RadButton” and you would be navigated to the style location.
Modifying the Style
To modify the original style to the target style, the Background, Foreground, and the Rounded Corner should be affected. Here is the XAML of the modified RadButton style.
<Style x:Key="RadButtonStyle"
TargetType="telerik:RadButton">
<Setter Property="BorderThickness"
Value="1" />
<Setter Property="BorderBrush"
Value="{StaticResource BasicBrush}" />
