Hi

I'd like to change background color of popup when end-user clicks RadDropDownButton ? What is the best way to bind with staticResource?

Hello Hyoung woo Lee,

 
A possible way to do this is to use Grid or StackPanel in the RadDropDownButton.DropDownContent and to set its Background like so:  

<telerik:RadDropDownButton  Content="Drop Down Button" VerticalAlignment="Center" HorizontalAlignment="Center" Width="125">
     <telerik:RadDropDownButton.DropDownContent>
         <StackPanel Width="125" Background="Aqua">
             <TextBlock Text="AAA"/>
             <TextBlock Text="BBBB"/>
             <TextBlock Text="CCCCC"/>
             <TextBlock Text="DDDDDD"/>
             <TextBlock Text="EEEEEEE"/>
         </StackPanel>
     </telerik:RadDropDownButton.DropDownContent>
 </telerik:RadDropDownButton>

Another approach to this issue is editing the style of the RadDropDownButton. You can change the ControlBackground SolidColorBrush that is used in the DropDownPopupBorder. I`ve attached a sample project illustrating such scenario.
