Textbox Inside RadioButtonList?

Question

Hi, I've got a RadioButtonList which is Databound to a LINQ data source. It will display a list of items which exist in a table in my database. However, for 1 of these items, I would like to display a TextBox rather than a Checkbox. The item is identified by a 0 or 1 flag in a separate column in my database. Can anyone suggest the best way of doing this? Thanks, Nick
