I am trying to use your listbox. I have set the PopulationType to BusinessObject and set the PopulationDataSourceSettings including specifying the ValueMember. This does not fill in the valuemember property of the control and if try to set that directly the popup menu only offers none. upon Execution I get:



InvalidOperationException

   Cannot set the SelectedValue in a ListControl with an empty ValueMember.

Could you please straighten me out on this?
