Hi Tina,

Try the following code to bind RadTreeView to SqlDataSource.

ASPX:

<telerik:RadTreeView ID="treeView" runat="server"></telerik:RadTreeView>

C#:

protected void Page_Load(object sender, EventArgs e)
   {
     SqlDataAdapter adapter = new SqlDataAdapter("SELECT * FROM Employees",ConfigurationManager.ConnectionStrings["NorthwindConnectionString"].ConnectionString);
     DataSet links = new DataSet();
     adapter.Fill(links);
     treeView.DataTextField = "LastName";
     treeView.DataFieldID = "EmployeeID";
     treeView.DataFieldParentID = "ReportsTo";
     treeView.DataSource = links;
     treeView.DataBind();
   }

For more information please take a look into documentation and Demo.

Thanks,
Princy.
