Hi,

Put the tables to be before the text box with the grand total and rely on the order of processing.

  private void granTotalInTheGroupFooter_ItemDataBinding(object sender, EventArgs e)
        {
            var tb = sender as Telerik.Reporting.Processing.TextBox;
            var totalTB1 = Telerik.Reporting.Processing.ElementTreeHelper.FindChildByName(tb.Report, "tbTotalTable1", true)[0] as Telerik.Reporting.Processing.TextBox;
            var totalTB2 = Telerik.Reporting.Processing.ElementTreeHelper.FindChildByName(tb.Report, "tbTotalTable2", true)[0] as Telerik.Reporting.Processing.TextBox;

            tb.Value = Convert.ToInt32(totalTB1.Value) + Convert.ToInt32(totalTB2.Value);
        }
