long delay between serverside JSON and jqGrid loadComplete on asp.net mvc site
- by ooo
i have an asp.net mvc site where i load a jqgrid with json data
public ActionResult GridData(GridData args)
{
IEnumerable<Application> applications = EntityModel.GetAll().ToList();
applications = FilterEntities(applications);
if (args.sidx.IsNullOrEmpty() || args.sidx == "Id")
{
args.sidx = "Name";
args.sord = "asc";
}
applications = applications.GridSort(args.sidx, args.sord);
var paginatedData = applications.GridPaginate(args.page ?? 1, args.rows ?? 10,
i => new
{
i.Id,
Name = "<div class='showDescription' Id= '" + i.MyId + "'>" + i.Name + "</div>",
MyId = string.Format("<a i.LastUpdated,
i.LastUpdatedColumn
});
return Json(paginatedData);
}
and here is my javascript code:
function doInitCrudGrid(controller, names, model, editable, querystring) {
jQuery("#grid").jqGrid({
mtype: 'POST',
url: "/" + controller + "/GridData?" + querystring,
datatype: "json",
colNames: names,
colModel: model,
imgpath: "/Scripts/jqGrid/themes/steel/images",
rowNum: 20,
rowList: [10, 20, 50, 999],
altRows: true,
altclass: "altRow",
jsonReader: {
root: "Rows",
page: "Page",
total: "Total",
records: "Records",
repeatitems: false,
id: "Id"
},
pager: "#pager",
height: "auto",
sortname: "Id",
viewrecords: true,
sortorder: "desc",
loadComplete: function() {
alert("Load Complete");
},
ondblClickRow: function(rowid) { }
});
i have a breakpoint on the
return Json(paginatedData);
line and that gets hit very quick but after that it takes about 10 seconds for the:
alert("Load Complete");
and for the rendering to show up on the web page.
Is there anyway to debug this or way to see why there would be this large delay between finishing the server side json and histting the loadcomplete on the javascript callback ?
