Hi Lalit M,
Thanks for the quick response...

Thanks,

    public partial class DefaultCS: XhtmlPage
    {
        

        private void GenerateTreeView()
        {            
            OleDbConnection dbCon = new OleDbConnection ("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Server.MapPath("~/TreeView/Data/Tree.mdb"));
            dbCon.Open();

            OleDbDataAdapter adapter = new OleDbDataAdapter("SELECT * FROM Links", dbCon);
            DataSet ds = new DataSet();
            adapter.Fill(ds);

            RadTree1.DataFieldID = "id";
            RadTree1.DataFieldParentID = "parentId";

            RadTree1.DataSource = ds;            
            RadTree1.DataBind();
            RadTree1.ExpandAllNodes();
