jquery - jqGrid Refresh From Server Issue -


i have struts2 jqgrid page loads fine. when navigator refresh button clicked want reload grid server. 

    <sjg:grid         altrows="false"         id="gridtable"         datatype="json"         editurl="%{editurl}"         filter="true"         filteroptions="{stringresult:true}"         gridmodel="gridmodel"         gridview="true"         height="600"         href="%{remoteurl}"                  loadonce="true"         navigator="true"         navigatoradd="%{editpermission}"         navigatoraddoptions="{             closeafteradd:false,             closeonescape:true,             reloadaftersubmit:true,             addcaption:'add record'}"          navigatordelete="false"         navigatoredit="%{editpermission}"         navigatoreditoptions="{             closeafteredit:false,             closeonescape:true,             aftersubmit:function(response, postdata) {                         return iserror(response.responsetext);                      }         }"         navigatorrefresh="true"         navigatorsearch="false"         oncompletetopics="loadcomplete"         onselectrowtopics="rowselect"         oneditinlinebeforetopics="beforeformload"         pager="true"         pagerbuttons="true"         rowlist="25,50,100"         rownum="25"         rownumbers="true"     >

i have following bind set datatype json when refresh button clicked.

$("#refresh_gridtable").bind("click", function(){     $("#gridtable").jqgrid("setgridparam", {datatype: 'json'});     return [true]; });

however, when click refresh button reloads data server on every other click. if perform client-side sort on specific column click refresh not reload server first click, second click refresh server without sort (the sort icons still visible @ point @ top of column), third click not hit server apply sort.

how refresh reload server each time, apply existing sort/filter fields?

the solution depends little underlying jqgrid use. if use free jqgrid 4.9 can use additional option of navgrid: reloadgridoptions: { fromserver: true }.

if use old version of jqgrid can use callback beforerefresh reset datatype "json" directly before reloading. don't use struts2 myself. don't know can specify callback beforerefresh

alternatively can use navigatorrefresh="false" remove standard refresh button navigator bar , use navigatorextrabuttons seems replacement navbuttonadd. if correctly understand option can specify free code of onclick, need. can use icon: "ui-icon-refresh" make custom button looks standarda refresh button. inside of onclick can set datatype: 'json' , trigger "reloadgrid".
