Я вызываю веб-сервис для заполнения jqGrid и хочу передать ему параметры
Я использую следующий код (на стороне клиента):
jQuery('#EmployeeTable').jqGrid({
datatype: function () {
var params = new Object();
params.page = 10;
params.Filter = true;
params.DateStart = null;
params.DateEnd = null;
params.TagID = null;
params.CategoryID = 3;
params.StatusID = 1;
params.IsDescription = true;
$.ajax({
url: '/Admin/IdeasJSON',
type: "POST",
contentType: "application/json; charset=utf-8",
data: JSON.stringify(params),
dataType: "json",
success: function (data, st) {
if (st == "success") {
var grid = $("#EmployeeTable")[0];
grid.addJSONData(data);
}
},
error: function () {
alert("Error with AJAX callback");
}
});
},
также существует пропотип веб-метода (MVC):
public JsonResult IdeasJSON(int? page, bool? Filter, DateTime? DateStart, DateTime? DateEnd, int? TagID, int? CategoryID, int? StatusID, bool? IsDescription)
Почему все эти параметры равны нулю?

jQuery(document).ready(function () {
var StatusID = null, Filter = null, page = null, DateStart = null, DateEnd = null, TagID = null, CategoryID = null, IsDescription = null;
if (jQuery.url.param('StatusID') != null) {
StatusID = jQuery.url.param('StatusID');

Filter = jQuery.url.param('Filter');
