What I am trying to do is using code behind add a root1 called "All Providers" then databind another datatable to make them childs of root1.

Code snippet:

RadTreeNode root1 = new RadTreeNode("All Providers");

RadTreeView1.Nodes.Add(root1);

RadTreeView1.AppendDataBoundItems =

true;

RadTreeView1.DataBind();

But what happens they al become roots in thier own right and do not appear as childs to root1.  I know there must be a way but cant find out how with the help file. 

Thanks for any help.

Ok I finally figured it out.  Had to go at it from a different approach.  I changed my data fetch statement to include fake parent and child ID's.  Then databind it.  Here is the code incase anybody else runs into this problem.



Code Snippet:

-- Get the data         
          DataSet dsp = new DataSet();
           DB.m_da.SetRead("SELECT 'All Providers' AS [Name], '0' AS [ID], null as tree union SELECT [FName] + ' ' + [LName] AS [Name], [ID],0 as [Tree] FROM Provider WHERE [Inactive] = 0 ORDER BY 1", 1);
            DB.m_da.Run(ref dsp);

-- Bind the data to the RadTree
            RadTreeView1.DataSource = dsp;

            RadTreeView1.DataFieldID = "ID";
            RadTreeView1.DataTextField = "Name";
            RadTreeView1.DataFieldParentID = "Tree";
            RadTreeView1.DataBind();
