UltraDropDown PopupItem wierd behavior
posted

Howdy,

I've got an UltraDropDownButton with an UltraWinTree as the PopupItem.  What I see when I click the DropDown to show my choices is that the wintree shows up with scrollbars, which is okay, but the wintree closes as soon as I mouse-up of any of the scrollbars (click, drag)

This is really unnerving since you haven't made a choice from the wintree - you have to re-clock the dropdown to see the list of choices.  Not indicative behavior of a dropdown.

I don't know where this behavior is set - in the dropdown or the wintree.

Thanks for any advice.

Corey.

    Hi Corey, 

    The dropdown should not be closing when you cilck on the tree. I tested this out and it worked fine for me.

    My guess it either:

    1. This is a bug that was already fixed. In which case you need to get the latest service release. How to get the latest service release - Infragistics Community
    2. Something in your code is closing the dropdown. Perhaps you are hooking the MouseDown, MouseUp, or Click event on the tree and not accounting for clicking on the scrollbars.
