WPF Editable Combobox IsFocused problem

Question

I am developing a Watermarked Combobox by modifying Combobox Control template. everything is fine when combo box is not in editable mode. but when i change edit mode to True, isFocused property never set to True. this is because in edit mode, combo box is using a Text Box. This is exact copy of this StackOverflow question: . there are no responces to that question. please drop a line if you know how to solve this. or please point me to links that provide Watermark Combobox implementation. Thanks, Rey.

You could try to use the IsKeyboardFocused or IsKeyboardFocusWithin instead

Answer 2

how i can set focus within a combo box(on initialization) so that user can start typing to search list.
