Howdy,

I am trying to create my TreeView's context menu after the TreeView has been bound and do so on the server. I am running into an issue however. The code below results in an empty Items collection on the contextMenu object. If I break in the code, after the DataBind(), I can see that the DataSource on the contextMenu has a collection of objects, but nothing is in the Items collection. Therefor, there is no context menu once the page renders.

                        protected void tabTreeView_OnDataBound(object sender, EventArgs e)         
                {         
                    RadTreeViewContextMenu contextMenu = new RadTreeViewContextMenu();         
                     
                    contextMenu.DataFieldID = "MenuItemId";         
                    contextMenu.DataFieldParentID = "ParentId";         
                    contextMenu.DataTextField = "DisplayText";         
                    contextMenu.DataValueField = "DisplayText";         
                    contextMenu.DataSource = this.GetUnusedMenuItems();         
                    contextMenu.DataBind();         
                     
                    tabTreeView.ContextMenus.Add(contextMenu);         
                }         

Why is the Items collection not being populated when I call DataBind? I can load the items in manually with a foreach loop (tested it and it works fine), but I didn't want to have to figure out the underlying hierarchy (the menu items I am using can be nested).

Thanks for any help,

Seth
