I may be wrong, but MyOrderHistoryPage.ascx is not set up to handle paging.
I added AllowPaging = "True" to the OrderGrid and was able to get the first page with paging tabs. However, when the page number is clicked, an exception is thrown.
"The GridView 'OrderGrid' fired event PageIndexChanging which wasn't handled. "
Can someone provide a solution to this?

Thanks,
Bruce.
