Finally figured out that although the container for the combobox has the ability to check for uniqueness, it is not implemented. There is no code in the valid of the combobox control to call UniqueValue! I cut the code out of the textbox valid and used it in my subclassed base combobox. I'm getting one error now but am tracking it down. Your code does work great. Thanks again.

Sally,

The textbox valid calls it's parent's UniqueValue method. That parent, as with most of the kContrls class controls, is the controlcontainer class. It looks like Kevin implemented code for this only in the cTextBoxl control.
You may want to pass your recommendation on to Kevin, maybe he'll implement it on the next release.
