Hello,

Please check below links.
Grid / Programmatic Binding :
By using above demo you can assign selectRoles in  NeedDataSource event.
you can assign SelectRoleFeature  in  DetailTableDataBind event (You can use DataKey to show particular role's feature).


Thanks,

Hello Susi,

Please do following changes in above code.

Please modify below code

protected void RadGrid1_DetailTableDataBind(object sender, Telerik.Web.UI.GridDetailTableDataBindEventArgs e)
   {

        GridDataItem dataItem = (GridDataItem)e.DetailTableView.ParentItem;
string RoleID = dataItem.GetDataKeyValue("ID").ToString();
      e.DetailTableView.DataSource = a.GetRoleFeatures(RoleID);
   }

Remove below code.

<SelfHierarchySettings ParentKeyName="ParentRoleFeatureId" KeyName="ID" />

Thanks,
