Then main concern of the interviewer is performance issue with Gridview paging. Because if you are using Gridview paging then it will be very costly in terms of memory. Because all records save in memory and can be performance issue. So simple answer is, in this case we will use
- Always use Sql Reader to bind the gridview
- Implement paging on Sql server side. Do not use Gridview paging.

Absolutely, but 1000 rows is not a "large amount of data", at least to me.
But I agree with your ccomment anyway. +5
