I just posted the code behind and the page - couldn't make it any simpler

other than a few context variables, self-contained - store number chief parameter

actually, as most of the heavy lifting is done on the client it could be possible that even an item grid with something in it could throw a javascript error

thanks

During my test, the object expected error points to the function GetFirstRow could not be found. The solution for this issue is by moving the GetFirstRow client side function to the head section of the page. Here is the snippet:

<head id="Head1" runat="server">
    <title>Order System</title>
    <script type="text/javascript" language="javascript">
        function GetFirstRow(gridObj) {
            var grid;
            var rows;
            //try {
            grid = ISGetObject("wgItems");
            //}
            //catch (err) {
            //    return false;
            //}
            if (grid == null)
                return false;

            rows = grid.TotalLoadedRows;
            if (rows == 1) {
                var rootTable = grid.RootTable;
                var firstRow = rootTable.GetRow(0);
                //firstRow.Select();
                rootTable.SelectRow(0);
            }
            return true;
        }
    </script>
</head>

For your next issue, we recommend instead of pasting the full code page in the thread you could attached the page as an attachment.

thanks!
