Hi i am using ultracombo for my application. The autocomplete works well but somehow, I need to make the combo show it's dropdown while the the user press a key which I don't know how. Can somebody tell me how to do that? Thanks.
You can use the PerformAction method to simulate any user-interaction with the control. So you can do something like this:
this.ultraCombo1.PerformAction(UltraComboAction.Dropdown);
I'm pretty sure the control will not drop down unless it has focus, though, so you probably need to set focus to it first.
