Question

Is it possible to avoid the automatic collapse of a Silverlight ComboBox after LostFocus?

Answer 1

I don’t think there is an easy way around this. The code below is copied from the disassembled code from the ComboBox Class. As you can see it closes always when hasFocus is false. I don’t think there is any way around this. Writing your own ComboBox is a solution.

private void FocusChanged(bool hasFocus) {     this.UpdateSelectionBoxHighlighted();     base.SetValueInternal(IsSelectionActiveProperty, hasFocus, true);     if (!hasFocus)     {         this.IsDropDownOpen = false;     } }
