Hello, thanks for replying, I tried your example and I've added 3 more products and the UltraTree control is displayed like my results, please how I can fix this.

            dt.Rows.Add(0,"cCategoryName 0","cCategoryDesc 0", 0, 0, "pProductName 0");
            dt.Rows.Add(1, "cCategoryName 1", "cCategoryDesc 1", 1, 100, "pProductName 100");
            dt.Rows.Add(1, "cCategoryName 1", "cCategoryDesc 1", 1, 101, "pProductName 101");
            dt.Rows.Add(1, "cCategoryName 1", "cCategoryDesc 1", 1, 102, "pProductName 102");
            dt.Rows.Add(2, "cCategoryName 2", "cCategoryDesc 2", 2, 103, "pProductName 103");
            dt.Rows.Add(3, "cCategoryName 3", "cCategoryDesc 3", 3, 104, "pProductName 104");
            dt.Rows.Add(4, "cCategoryName 4", "cCategoryDesc 4", 4, 105, "pProductName 105");
            dt.Rows.Add(1, "cCategoryName 1", "cCategoryDesc 1", 1, 106, "pProductName 106");
            dt.Rows.Add(2, "cCategoryName 2", "cCategoryDesc 2", 2, 107, "pProductName 107");
            dt.Rows.Add(3, "cCategoryName 3", "cCategoryDesc 3", 3, 108, "pProductName 108");

Please, my UltraTreeView are grouped by product and within the list of categories.

This is my Code from Initialize the UltraTree

            If (e.Node.Level = 0 And OldValue <> e.Node.Cells("cCategoryID").Text) Then

                e.Node.Cells("cCategoryID").Column.Visible = True
                e.Node.Cells("cCategoryName").Column.Visible = True
                e.Node.Cells("cDescription").Column.Visible = True

                e.Node.Cells("pProductID").Column.Visible = False
                e.Node.Cells("pCategoryId").Column.Visible = False
                e.Node.Cells("pProductName").Column.Visible = False

                e.Node.Visible = True

            ElseIf (e.Node.Level = 1) Then

                e.Node.Cells("cCategoryID").Column.Visible = False
                e.Node.Cells("cCategoryName").Column.Visible = False
                e.Node.Cells("cDescription").Column.Visible = False

                e.Node.Cells("pProductID").Column.Visible = True
                e.Node.Cells("pCategoryId").Column.Visible = True
                e.Node.Cells("pProductName").Column.Visible = True

            Else
                e.Node.Visible = False
            End If
            OldValue = e.Node.Cells("cCategoryID").Text
