Avoiding onrowcommand event in paging

Hi in my gridview when i click on page tabs i get to first rowcommand and then paging event.Some pages i am getting error "index out of range",as i am setting the e.commandargument to rowindex and getting it back in rowcommand to acces the servercontrols.But i think during paging it first fires the onrowdatabound and e.commandargument is set to the page no=pageindex+1.That is why i am getting index out of range error as before setting the pageindex it tries to find out e.commandargument.
