                  { datatype: 'json' }
                  );

            jQuery.extend(jQuery.jgrid.search, {

Hello Puran,

Did you get a chance to look at JQGrid demo site[^]. They have a example for doing the search.
Basically you will have to create a service which will take the filter parameters and return the JSON. The client side script will invoke this service on click of the search button and will then trigger the reloadGrid.

JavaScript

function doSearch(){
    var strFName = document.getElementById('txtFName');
    var strLName = document.getElementById('txtLName');
    jQuery("#mygrid").jqGrid('setGridParam',{url:"YOUR_SERVICE.asmx?firstName=" + strFName + "&lastName=" + strLName, page:1}).trigger("reloadGrid");
}

Regards,
