Newbie question:
I have a bunch of comboboxes, and I only want the user to be able to accept a value in the list. I want them to be able to type in the field and have it auto position to the corresponding value in the list which works nicely, but how do I validate that the entry is one of the list items while they are typing?
For instance:
if the values are [Brian, Frank, Jeff, Martin] and they type JEFF it positions to JEFF, but if they type JEFFR, it stops positioning, but allows the entry.
Any suggestions?
