I have a combobox initialized as follows:

I have BoundColumn = 1, MatchRequired = TRUE and the initial Value set to blank.

The problem is when you click into and then out of the combobox without selecting anything from the drop-down, the "blank" value triggers the MatchRequired condition and you get an "Invalid property value" error message. Is there a way to ignore the initial blank state without setting MatchRequired = FALSE?

I've got a single-column combobox with the exact same initial settings and it does not have this problem.
