[CLOSED] ComboBox SelectedItem.Value Showing Instead of DisplayField [0.8.2.983]
I get the following error below when I change the selected index to something other then 0 on the combobox and when a postback occurs it shows the selected value instead of the display value and I finally get an error. This does not happen when the selected index is 0 for the combobox. Do I have something setup incorrectly on my combobox.
The Store gets bound to a System.DataView.
