I have four UltraComboEditors onm a form, where the data source is a List<>. I have a property for the DisplayMember and the ValueMember. I haven't set an initial value of the Combo, but I have net the NullValue property. When I try and tab out of the combo without selecting a value, I can't tab out. It's like there is some kind of validation going on but I don't know where?
Any thoughts on this?
Never mind, I fixed the problem. I had limit to list set to True, which is why I could not move from one combo to the next with the Tab. The Null value wasn't in the data that was bound to the combo.
Solution, check to see if Limit To List is set to true when you have the combo type set to DisplayList.
