javascript - JQgrid FreezeColumn not freezing headers? -

-

i new jqgrid , have been attempting freeze first column in grid horizontal scrolling not effect column.

i have frozen: true in colmodel, calling jquery("#grid").jqgrid('setfrozencolumns');.

this correctly freezes column data, scroll right, column headers scroll me. how can freeze headers too?

thank much!

sample code: 

jquery("#taskgrid").jqgrid({ datatype: "jsonstring", colnames:['task id','task name', 'role info'], colmodel:[     {name:'taskid',index:'taskid', width:100, frozen: true},     {name:'taskname',index:'taskname', width:200},     {name: 'roleinfo.1', index: 'roleinfo.1', width:100, formatter: 'checkbox' }  ], jsonreader: {repeatitems: false}, datastr: json.parse(document.form.taskdata.value), rownum:50, pager: '#pager2', sortname: 'taskid', viewrecords: true, sortorder: "desc", caption:"json example", height: "750",  width: "350", shrinktofit: false });jquery("#taskgrid").jqgrid('setfrozencolumns');

try use free jqgrid 4.13.4 instead of guriddo jqgrid js 5.1.0, use currently. first of includes many fixes in frozen columns, contains many enhancements , free in opposite guriddo jqgrid js (see prices here). try free jqgrid can use load jqgrid directly cdn (see the wiki article).

i'd recommend additionally use datatype: "local" , data: jquery.parsejson(document.form.taskdata.value) instead of datatype: "jsonstring" , datastr. datatype "jsonstring" if need to prevent local sorting of input data during initial loading. if use datatype: "local" input data sorted locally based on sortname: 'taskid' , sortorder: "desc" before there displayed.
