I'm working on a custom module that uses datagrid for which I'm trying to create some totals in the footer.  I'd like to use the OnItemDataBound subroutine to put the totals in the footer.  However, I keep getting an error when I add a OnItemDataBound parameter to my datagrid. I'm obviously doing something wrong but I can't figure out what it is.  My datagrid has the following parameters:
<asp:DataGrid ID="dgB2BViewCart"
            AutoGenerateColumns="false"
            ShowFooter="true"
            OnItemDataBound="dgB2BViewCart_ItemDataBound"
            Width="100%"
            CellPadding="3"
            GridLines="None"
            CssClass="Datagrid_Container"
            runat="server" >

The error I keep getting is:
DotNetNuke.Services.Exceptions.ModuleLoadException: D:\Websites2005\DNNDev\DesktopModules\PilotInterface\View.ascx(1041): error BC30456: 'dgB2BViewCart_ItemDataBound' is not a member of 'ASP.desktopmodules_pilotinterface_view_ascx'. ---> System.Web.HttpCompileException: D:\Websites2005\DNNDev\DesktopModules\PilotInterface\View.ascx(1041): error BC30456: 'dgB2BViewCart_ItemDataBound' is not a member of 'ASP.desktopmodules_pilotinterface_view_ascx'. at System.Web.Compilation.BuildManager.CompileWebFile(VirtualPath virtualPath) at System.Web.Compilation.BuildManager.GetVPathBuildResultInternal(VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile, Boolean throwIfNotFound, Boolean ensureIsUpToDate) at System.Web.Compilation.BuildManager.GetVPathBuildResultWithNoAssert(HttpContext context, VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile, Boolean throwIfNotFound, Boolean ensureIsUpToDate) at System.Web.Compilation.BuildManager.GetVPathBuildResult(HttpContext context, VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile, Boolean ensureIsUpToDate) at System.Web.UI.TemplateControl.LoadControl(VirtualPath virtualPath) at DotNetNuke.UI.ControlUtilities.LoadControl[T](TemplateControl containerControl, String ControlSrc) at DotNetNuke.UI.Modules.ModuleHost.LoadModuleControl() --- End of inner exception stack trace ---

If I take the OnItemDataBound attribute out of the datagrid definition I do not get the error. With it in, the error appears.

Any ideas of where to look for the problem would be greatly appreciated.

In order to hook up an event handler in your .ascx file markup, the event handler must be given Public or Protected scope in the code behind and not Private scope as the .ascx markup inherits the code behind's class and would not be able to "see" a method marked private in its base class. When you eliminated the Private scope keyword from the class's dgB2BViewCard_ItemDataBound method, the default scope is Public.

I also noticed that you are also hooking up to the same ItemDataBound handler by including the Handles keyword in the declaration of the Sub dgB2BViewCard_ItemDataBound.  Use of both approaches to hooking up the same event handler should be avoided. If you were to remove the attribute OnItemDataBound="dgB2BViewCard_ItemDataBound" from the DataGrid's attribute markup in the .ascx file, the application of Handles dgB2BViewCard.ItemDataBound to the method in the code behind shoud be all you need. In that case, the method scope can in fact be made Private.
