It is possible to add complex content (i.e., server controls and HTML elements) in a RadButton 
		instead of plain text. There are three ways to achieve this: 
	
		- Set the ContentTemplate property.
    
		- In the markup of your page you can add controls to the ContentTemplate inner property as shown below:
 
				<telerik:RadButtonrunat="server"ID="RadButton1"Width="90"Height="90">
     <ContentTemplate>
         <span>RadButton Content</span>
     </ContentTemplate>
 </telerik:RadButton>
 
 
- In the code-behind, you can set the ContentTemplate property to an instance of a class that implements the ITemplate interface.
		
 
- Add controls to the Controls collection of the RadButton instance from the code-behind.
		
		Important: Please note that the RadButton is rendered as a 
		span HTML element, wrapping the inserted content, so you should add in the template only 
		inline elements in order to maintain XHTML compliance .
