Attached you will find a small MVC sample, based on the scenario described. You will notice that in order to properly populate the selected value for the DropDownTree editor, I had to retrieve it in the Gredi.Edit() event
and set it manually on the DataBound() event of the DropDownTree
selectedItem = e.model.EmployeeID;
The above is needed because of the hierarchical structure of the editor DataSource, which will cause several calls to the remote to be initiated on its initial load.
