compare ajax gridview and asp.net gridview control in asp.net

As for obvious reasons ajax gridview is better as any operation on it won't be requiring any postback.

And going to ASP.Net gridview then it has its own features for a particular requirement like where there are no or less operations on gridview then asp.net is useful there.

For example: -For bulk data,

The most important thing about bulk data is not to move bulk data. Create you own paging in a gridview and do not retrieve more records than 1 gridviewpage from the database. Otherwise performance drops immediatly.
an example can be found here.

So, Both are good it totally depends on your requirement how you use them.

I hope you understand.
