jQuery Grid Plugin - jqGrid

Hi ,

I am facing a problem w.r.t sorting, i am able to sort only data which is loaded in current page

is there any option i need to set so that sorting is done considering data across all the pages.

thanks in advance.

Below i have pasted the code :

jQuery("#docSearch").jqGrid({
                                    datatype: "clientside",
                                    height: 250,
                                    colNames:[dbColumnName[0], nameCol,dbColumnName[2],dbColumnName[3],
                                                     ........................

                                                     ........................

                                             dbColumnName[28],dbColumnName[29],dbColumnName[30]
                                             ],
                                    colModel:[{name:'column_0',index:dbColumnValue[0],width:10,align:"center"},
                                             ............

                                            ..............
                                              {name:'column_29',index:dbColumnValue[29], width:20,align:"center"},
                                              {name:'column_30',index:dbColumnValue[30], width:20,align:"center"}
                                             ],
                                             
                                  imgpath: gridimgpath,
                                   multiselect: false,
                                   autowidth: true,
                                   shrinkToFit:true,
                                   loadonce: true,
                                   caption: "Document Search Result"
                                   });.navGrid('#pager1',{edit:false,add:false,del:false});
