you not rebinding grid once page number changes.

your code this:

protected void onpageindexchanging(object sender, gridviewpageeventargs e) {     gridusers.pageindex = e.newpageindex;     this.c.getcst(); } 

you need instead:

protected void onpageindexchanging(object sender, gridviewpageeventargs e) {     gridusers.pageindex = e.newpageindex;     gridusers.datasource = c.getcst();     gridusers.databind(); }
