I am getting an issue in handling look up edit control [dropdown] in DevEx GridView for windows forms. There are 2 dropdowns in the grid, which are cascading dropdowns. Once the value of first dropdown is selected, second dropdown should populate the relevant values. However cascading is not happening even though I set the datasource of the second dropdown based on the selection in first one. Sample code given below.
SetPlanDataSource(CType(CType(sender, DevExpress.XtraEditors.LookUpEdit).EditValue, Integer))
If _listOfPlans.Count = 0 Or IsNothing(_listOfPlans) Then
PlanRIlue.DataSource = Nothing
PlanRIlue.DataSource = _listOfPlans
