[Solved] ComboboxColumn dropdown mutex

[toto rto]

Hi,

We have a long ComboboxColumn with multiple entries and we're trying to make the drop-down list to be mutually exclusive.
Each drop-down list entry is to be used once only and removed from the drop-down list once selected.
How should we go about doing something like this?

Thanks.

Hello Toto Rto,

Actually, it is not quite recommended to remove any items from the source of the combo box since you will break its correct behavior. The closest we can get is to make the used items disabled. Please take a look at this article for a reference. Will this approach suit your needs ?
