ComboBox Input ,wpf -

I have a combo box and its item source is a SQL table.

I like that the user will like that value and if the price is not in the list, then he will be able to type the value in the combo box. Is this possible?

Thank you.

Your inconsistent property must be set in Cobbox to True. This will allow you to edit the content and to select any populated items in the combo box.
