Hi, My grid ComboBox has a display member(string), value member(int) and data source as an empty binding list(ArrayList). So, it is displaying a message, 'Cannot bind to new display member' which is the default behaviour of a ComboBox. When I load the form, it is showing those respective cell values as integer values(Value Member) instead of string values(Display Member) and showing red color exception as shown in attachment on cell click. Now, I need a ComboBox in grid so that it should not show any such message when the binding list has no data. Thanks in advance.
