I've got a combobox where the user can either pick a value from the control or type in a NEW value and have the new value saved.

What I'm looking for is a way to have "Type in New Value" displayed in the Text portion of the combobox BUT not have it as part of the control selections. Sorta like Microsoft did with Vista where a textbox may display "Password" and then when you place the cursor in the box the "Password" text disappears.

Any one have any suggestions?

Thanks!
