The pager elements of jqGrid will be created at the grid initialization. So if you not need the pager buttons you should use$("#pager_center").hide();
to hide all information about the pager or $(".ui-pg-button","#pager_center").hide();
if you don't want to show only the first, previous, next and last pager buttons. In the code above I supposed that the id of the pager is id=”pager”.
