Style border of DropDownButton popup

[Hans]

What's the easiest way to style the border of the WPF DropDownButton popup?

Hello Hans,

You need to set custom template to the RadDropDownButton, where the Popup with x:Name="DropDownPopup" needs to be changed. Please let me know which is the theme that you apply in your application and which is the theming mechanism that you use - StyleManager or implicit themes? What kind of modification do you need? And I will help you further with this.

Hi Sia,

I'm using the Office2013 theme with implicit styles. The popup has a gray border which I'd like to change to another color.

Kind regards
Hans

Hello Hans,

Please find attached a sample solution how to do this. In the custom style I only changed the value of the BorderBrush in the Popup from:
BorderBrush="{telerik:Office2013Resource ResourceKey=HighDarkBrush}"
to:
BorderBrush="Red"

You can remove some of the visual states also to simplify your style if you use only the default PopupPlacementState and DropDownButtonPosition.
