    I have a RadDropDownTree and i want to set the selected value, I do this with the ddtDiagCategorie_OnNodeDataBound, my node is selected in the list when i open it, but th text is not dispay at first time, I tried with DefaultMessage property with no result. I was thinking that the right manner was using the SelectedText or SelectedValue like a normal dropdown, but th property is readonly, how does I have to do this. (The big consequence is after a modify, if the user don't go to selecte the value in the DropDownTree, he save an empty value in the database...)

    My code on the event :

    protected void ddtDiagCategorie_OnNodeDataBound(object sender, DropDownTreeNodeDataBoundEventArguments e)
                if (BilletCourant != null && BilletCourant.IdCategorie.HasValue)
                    if (e.DropDownTreeNode.Value.Equals(BilletCourant.IdCategorie.Value.ToString()))
                //ExpandAllNodes sur ce contrôle
                e.DropDownTreeNode.Expanded = true;
