RadDropDownButton.DropDownContent on top of the modalbackground after ShowDialog()

[Ted]

Hi,
I have a question for RadDropDownButton and Modal window in XBAP model. If you click the dropdown item of RadDropDownButton, it will popup the modal window (ShowDialog), but the DropDownContent doesn't disappear and it is on top of the ModalBackground. If you click the other place, the DropDownContent disappears. I want to know how can i resolve it?

Hi Ted,
You could try to close it manually in the event handler like this:

this.RadDropDownButton1.IsOpen = false;

If you have more questions please feel free to ask.

Best wishes,
