In a previous like I setup the jqgrid colmodel, etc.  In that call I start with a datatype:'local'.

Thank you

I would have expected the preload events to fire but they do not.

If I do a relaodgrid, all the "pre" events fire.  IE "serializeGridData", "beforeRequest", "beforeProcessing", "loadBeforeSend".

In summary, when I call 'setGridParam' no events fire except for loadError.

If I do a "reloadGrid" all the pre events fire and the grid loads successfully.

So what is causing loadError to fire and how do I ignore it when it's not a result of a service call?

grid.jqGrid('setGridParam', {
    url: svc.getWebAPIUrl('Incident', 'GetIncidents'),
    datatype: 'json',
    serializeGridData: function (pdata) {
        debugger;
        var s = (pdata.page - 1) * pdata.rows;
        var e = pdata.rows;

        return 'csId=' + pdata.CSID + '&folderid=' + pdata.folderId +
               '&uId=0&s='+ s + '&e=' + e;
    },
    beforeProcessing: function (data, status, jqXHR) {
        debugger;
    },
    beforeRequest: function () {
        debugger;
    },
    loadBeforeSend: function (xhr, settings) {
        debugger;
    },
    loadComplete: function () {
        alert('OK');
    },
    loadError: function (jqXHR, textStatus, errorThrown) {
        //debugger;
        alert(util.getErrorMessage({jqXHR: jqXHR, textStatus: textStatus}));
    }
});
