    PROJECT DESCRIPTION

    This sample demonstrates a hierarchy grid with a calculated column in its master table, which displays the sum (or any other defined Aggregate as a matter of fact) of values in the detail tables. The logic happens within the boundaries of the mystical land of the ItemDataBound event:

    protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridFooterItem && e.Item.OwnerTableView.Name == "DetailTableName")
        {
            GridFooterItem footerItem = e.Item as GridFooterItem;
            GridDataItem parentItem = footerItem.OwnerTableView.ParentItem;
     
            parentItem["Total"].Text = footerItem["Freight"].Text;
            footerItem.Display = false;
        }
    }

    Here is a video demonstrating the geekily satisfying result:
