In that Selection of list value changed event firing and showing msgbox , after giving ok of that msgbox, shown list not getting hide
In what event are you showing the MessageBox?
What version of the controls are you using?
This looks like a really old bug that was fixed many years ago. You could work around it very easily by closing the dropdown before you show the MessageBox.
Event : Combo_Value changed
Version : Net Advantage 11.1 Clr2X
This is very new bug , right now i am facing , after giving ok of that msgbox , the shown list not at all getting hide,
help me out to fix this issue
Hello,
I am checking about the progress of this issue. Please let me know If you need any further assistance on this.
ValueChanged is an odd place to show a MessageBox.
This event will fire as the user is typing in the control and they may not have finished. Or it will fire as the user uses the arrow case to navigate the list and they may not have gotten to the item they want, yet.
So showing a MessageBox in ValueChanged seems like a very strange UI to me.
I tried this out, anyway, and I am seeing the results you describe. The message box is taking focus away from the control while it's in the middle of processing a click, so it probably never completes processing the mouse message and so it never closes up.
You can easily work around this by closing up the Combo in code before showing the MessageBox.
if (this.ultraCombo1.IsDroppedDown) this.ultraCombo1.ToggleDropdown();
