I have an asp.net form (C# code behind). I'm using the combo box control from DevExpress. The combo box shows a list of countries to select from. It's one of several controls on the form, all tied to a database table. When I insert a record, I have no issues. When I bring a record up for editing, if I make a change to the combobox dropdown (and any other edits, it works fine. However, if I bring it up and make edits without making a change to the value in the combobox, I get the "Error converting data type nvarchar to int" error. I am trying to find out how to handle this. The combobox displays the Country that has been selected, but a numeric value is what is stored in the table. Any ideas?
