Will someone please tell me where in the documentation it states that the DataValueField and the DataTextField must be set for this control to behave. I spent over 10 hours trying to track down why when I bind this control to a List<CustomBusinessObject> that the selectedrowchanged event does not fire the first time the user selects a value from the dropdown, and the selectedindex property always returns 0. I am getting tired of spending so much time debugging issues with IG web controls. The Win controls are great.
