Ajax网格选项和postData

Question

这里有一个问题，我使用postdata将参数从ASPX文件发送到webservice，而不使用ajaxGridOptions: { contentType: 'application/json; charset=utf-8'}。

问题是，网格不会显示来自webservice的内容，而且一旦我们使用了这个ajaxGridOptions: { contentType: 'application/json; charset=utf-8'}，网格就不会将任何参数传递给webservice。这是我们的jqgrid代码，请帮助

$(document).ready(function () {
  var myGrid = $("#list");
  myGrid.jqGrid({
    url: '/priParentsContribution.asmx/getListOfTeachers',
    datatype: 'json',
    mtype: 'POST',
    //ajaxGridOptions: { contentType: 'application/json; charset=utf-8'}
    jsonReader: {
      repeatitems: true,
      root: "d.rows",
      page: "d.page",
      total: "d.total",
      records: "d.records"
    },
    colModel: [{
        name: 'feePurpose',
        index: 'feePurpose',
        width: 100,
        editable: true,
        edittype: 'select',
        editoptions: {
          value: "0:--Select--;Books:Books;Uniform:Uniform"
        }

    postData: {

    ajaxGridOptions: {
      contentType: "application/json",
      success: function (data, textStatus) {
        if (textStatus == "success") {
          var thegrid = myGrid[0];
          thegrid.addJSONData(data.d);
          thegrid.grid.hDiv.loading = false;
          switch (thegrid.p.loadui) {

      }

  $("#reload").click(function () {
    myGrid.trigger("reloadGrid");

  myGrid.jqGrid('navGrid', '#pager', {

    search: false,

  myGrid.jqGrid('inlineNav', '#pager');
});

必须将节点：ajaxGridOptions添加到jqGrid options对象中。
