    PROJECT DESCRIPTION

    RadGrid provides built-in group aggregates, which are calculated automatically on server-side:
    http://demos.telerik.com/aspnet-ajax/grid/examples/functionality/grouping/group-footers/defaultcs.aspx

    When using Batch editing, the changes made by the user are kept on the client before clicking the Save Changes method explicitly. This sample demonstrates how to update the total values dynamically, so the user may see how the changes will affect the aggregated values, even before committing them.

    this example doesn't work.  It hangs up on var tableViewEl = $(tableView.get_element());  The error is "Object Expected".  That is all the error says and I got no way how to figure out what is expected to fix it.  Please help correct this.  I need to update the group and master totals when a cell is updated in a batch mode radgrid.

    Hi Patrick,

    The sample actually works correctly, but if you copy the script logic, you will also have to include the $ jQuery instance. There are several ways to achieve that:

    You can use the following definition of the RadScriptManager:
    <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
        <Scripts>
            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />
            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />
            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js" />
        </Scripts>
    </telerik:RadScriptManager>

    Alternatively, you can use var $=$telerik.$; or directly $telerik.$.

    Regards,
