jqGrid Refreshing Local Data (JSON Object)

Question

I\'m trying to use jqGrid with local data and I\'m finding a couple of issues:

I\'m initializing the thing like so:

function refreshGrid($grid, results)
         


        

Answer 1

Following works for me when refreshing data on an existing grid:

var gridData = [...];

var grid = jQuery('#gridId');
grid.jqGrid('clearGridData');
if( grid.get(0).p.treeGrid ) {
    grid.get(0).addJSONData({
        total: 1,
        page: 1,
        records: gridData.length,
        rows: gridData
    });
}
else {
    grid.jqGrid('setGridParam', {
        datatype: 'local',
        data: gridData,
        rowNum: gridData.length
    });
}
grid.trigger('reloadGrid');

I had to do it this way because reloadGrid() calls populate(), populate() calls addLocalData() and passes the return value to addJSONData(), but for treeGrid == true, addLocalData() returns nothing, and addJSONData() subsequently does nothing.
