How to create custom paging in GridView

If you want to create custom paging in Gridview then you have to apply your own logic. Because by default Gridview shows no. of pages according to page size and records in GridView. So for custom paging suppose page size is 10 then  you have to count all records from table and select only 10 records and you have to generate page button on basis of total records and on click of particular page you have to fetch only record for that page. It works very fastly as compare to general gridview binding.
