Avoid postback when binding gridview

Hi there,

I'm binding a gridview with tha datasource.I'm also bindin some textboxes dynamically. In my db I have more than 2500 records. I have paging in my gridview. Now when i click on index chage whole page is getting refreshed. When I click on Show all records, It displays all records.

All I just need to do is avoid postback on index change. And also please provide the code how to handle the selected index value if u suggest me to use Ajax or something else.

Thanks & Regards,

MZee.
