Sir,
The default paging of datagrid is somehow use too much resource, so I am
using Stored procedure for the paging. You can find my Stored procedure at
the end of this message.
It works fine to do paging like this, however, I have found it difficult to
do paging and sorting at the same time.
For example, in my case, my boss asked me to do sorting on EmailAddress,
ZipCode, ActivityName and Coupon.
Any recommendation how should I achieve this?

Kind regards
