I have a combobox that is defined as a "drop down list" in a grid.

If a value has been programatically changed to something that is not in the list (populated using a select statement), the value will not show whenever the combobox has focus.

Further Info:

The value show if it doesn't have focus.
The value shows if the value is part of the list of values in the combobox.
At any time later if the combox receives focus again, this value will not be displayed.
