>I want the Items combo to be blank when I select a different category. Unfortunately, it behaves this way - temporarily shows the item correspoding to the previously selected index and then goes blank. Any way to prevent wrong item to display?

I see in another post that you already figured this one out, changing

                this.cboItems.SelectedIndex = 0; //Start from the empty item

-to-

                this.cboItems.SelectedIndex = -1; //Start from the empty item

was what I was going to suggest. Just thought I'd reiterate in response to the post that asked the question, in case there are interested lurkers.

However, it seems like I can only select category once to get the Items displayed correctly - every time I select anyhing else it remains the same - it should clear the Items combo value and allow me to select items for the selected category - this part I can not get to work as hard as I already tried.
