The help text says for Combo Box says:

"An item in a ComboBox control can be disabled by placing a backslash (\) before the item. If the item begins with a backslash and should not be disabled, add an additional backslash."

I put a backslash before the items I wanted to be disabled and all I got were items with backslashes displayed as the first character. None of the items were disabled.

How do I disable items in a combo box?

Thanks in advance.
