What is the best way to do this

[Tony]

Hello!

I'm converting some program from progress to C# using winform and
Infragistics .NETAdvantage
When a user want to select reason for waiting there are for example 10 items
to choose among but in some cases none of these
items are correct so the user must be able to enter a text string to give
the reason.
I don't want to add an extra textbox for this. The best thing would be to
click in a suitable control a combobox for example and if no items suits you
can enter
text directly into this control.

You can do exactly that with a Combo Box....
