In every button in the toolbar add to following line: _Screen.ActiveControl.SetFocus(). That will force the LostFocus() to fire and will commit the modification. This behaviour occur because toolbar doesn't "get" focus.

>In my application I'm using a toolbar like the one in Tastrade. I have notice that when the user is in a combobox and selects the toolbar to save the lost focus event doesn't fire. What do I need to do to correct this occurance.
