Hide Enum of combobox during runtime.

Hi all,

The case is I need a combobox showing element partially based on selection of another combobox.

I found a solution from google which manage the element by coding, by building combobox in init of form, so I can remove and insert element of combobox in another combobox.selectionChange.

But so far my understanding is to save a combobox value into datatable, the combobox need to be bound.

So how can I save the unbound combobox value? By setting the value into another non-visible control(bound) in form while selectionChange? Or maybe there is another easier way?

Thanks
