c# - Gridview scroll by keeping paging fixed -

i have asp:gridview has large datasource of 600 rows. gridview has been paged show 100 rows per page. need add scroll limiting height of gridview 500px

i have done using

.fixed-height {     max-height : 500px;     overflow-y : scroll; } 

on outer div.

the issue page selector part of grid view table , hence @ end of scroll. there way fix position of last tr outside scroll?
