So I really would like to use the popup edit form.  Telerik’s radgrid is a really powerful control that provides the plumbing already for data maintenance.  The problem is the way it interacts with User Controls or Master Pages.  Do you have any good recommendations, really optimized examples, of layout for a telerik navtree on the left and a sort of content area on the right?  The content area could be a user control, a .aspx page (something encapsulated away from the rest of the menu system). 

Your solution to the user control isssue listed here:
http://www.telerik.com/help/aspnet-ajax/ajxloadusercontrols.html
requires me to rebuild the user control (with the grid) every time!  Should I be doing it this way?  If that is the case, do radgrids in user controls make sense?  (this example doesn't include a grid)

Your demo’s website, doesn’t use an overall master page, when it seems that this would make sense.  It seems to use user controls, but they are not ajax’d and flicker.  If you have a recommendation or a sample project (could be static static, I don’t care for now), that implements the layout that I looking for, I would really appreciate it.

Thanks!

protected void treeView_ContextMenuItemClick(object sender, RadTreeViewContextMenuEventArgs e)
    {        
        RadTreeNode clickedNode = e.Node;

        switch (e.MenuItem.Value)
        {
            case "Add":
                textbox1.Text = clickedNode.Text;
               
                break;
            case "Edit":

                clickedNode.Text = textbox1.Text;
                break;
            case "Delete":
                clickedNode.Remove();
                break;
        }
    }

"Edit" case is working well
but "Add" case is not working 

I wanna some advice
thank you
