This takes several seconds to render 200 rows, both in IE and FF:

$('#PreviewGrid').jqGrid({

datatype: 'local',

loadError: function(xhr, st, err) {

ErrorHandler(xhr, st, err)

colNames: JsonResponse.columnNames,

colModel: JsonResponse.columnModels,

loadui: 'disable',

autowidth: true,

shrinkToFit: true,

height: 'auto',

gridview: true,

rownumbers: true,

sortorder: 'desc',

viewrecords: true,

caption: 'Preview',

gridview: false,

hidegrid: false,

rowNum: 199

});

$.each(JsonResponse.rows, function(index, item) {

$('#PreviewGrid').addRowData(index, item);

});

I've tried loading the grid via addJsonData, and can't get it to work. Grid is rendered with the header rows, but no rows are rendered:

$('#PreviewGrid').jqGrid({

datatype: 'jsonstring',

loadError: function(xhr, st, err) {

ErrorHandler(xhr, st, err)

colNames: JsonResponse.columnNames,

colModel: JsonResponse.columnModels,

loadui: 'disable',

autowidth: true,

shrinkToFit: true,

height: 'auto',

gridview: true,

rownumbers: true,

sortorder: 'desc',

viewrecords: true,

caption: 'Preview',

gridview: false,

hidegrid: false,

rowNum: 199

});

var mygrid = $('#PreviewGrid')[0];

mygrid.addJSONData(JsonResponse.rows);

What am I missing to make addJSONData work?

Any help would be greatly appreciated.

Regards,

Bob

Hello,

Check what is expected when using json. Not sure, but I think you should do:

mygrid.addJSONData(JsonResponse);

instead of

mygrid.addJSONData(JsonResponse.rows);
