    Hi!

    Is it possible to make the background of the DropDownContent in the RadDropDownButton transparent?

    It seems I'm not able to change the default white color...

    (I've attached a screendump of my challenge. I want to get rid of the white background surrounding the inner black border).


    Thanks!

    Jon

    Hi Jon,

    You will need to edit the ControlTemplate of the RadDropDownButton (read more about editing ControlTemplates in Blend) and change the Background color of the DropDownPopupBorder element.

    By default the DropDownPopupBorder Background property is bound to a SolidColorBrush resource named ControlBackground so if you change this brush's Color to Transparent, the DropDownContent Background will be transparent.

    I attached a sample project to get you started. Let us know if we can further assist you.

    All the best,
