Jquery jqxGrid下拉列表问题

我正在尝试用下拉列加载gjqxGrid，我在JSFIDLE:中使用了示例json，效果很好。但当我尝试在我的项目文件中使用相同的代码时，下拉列表为空，我已经检查了数据格式，这很好。 下面是项目文件中的代码

        var source_app =
            {
                datatype: "json",
                datafields:[
                    { name: 'id' },
                    { name: 'name' },
                    { name: 'count' },
                    { name: 'drop'},
                    { name: 'drops'}                        
                ],
                url: "settings/scenario_count2.php",
                cache:false,
                                updaterow: function (rowid, rowdata, commit) {
                    var data = "update=true&" + $.param(rowdata);
                    $.ajax({
                        dataType: 'json',
                        url: 'settings/scenario_count2.php',
                        cache: false,
                        data: data,
                        success: function (data, status, xhr) {
                            // update command is executed.
                            commit(true);
                        },
                        /*
                        error: function(jqXHR, textStatus, errorThrown)
                        {
                            commit(false);
                        }*/
                    });
                }
            };
            var dataAdapter_app = new $.jqx.dataAdapter(source_app);
            dataAdapter_app.dataBind();

//下面是我的Jqx网格初始化代码 //方法1

$("#scenario_grid2").jqxGrid(
            {
                width: 520,
                height: 253,
                source: dataAdapter_app,
                editable: true,
                theme: theme,

                selectionmode: 'multiplecellsadvanced',
                columns: [
                    { text: 'Id', hidden: true, editable:false, columntype: 'textbox', datafield: 'id'},
                    { text: 'Name', columntype: 'textbox', datafield: 'name', width: 140 },
                    /*{ text: 'Drop', columntype: 'NumberInput', datafield: 'drop', width: 60 },  */

                       { text: 'Drop', 
                       datafield: 'drop', width: 160, columntype: "dropdownlist", 
                       initeditor: function (row, cellvalue, editor) {
                       editor.jqxDropDownList ({source: dataAdapter_app.records[row].drops });

                       }},

drops列具有需要在下拉列表中pe的值数组。另外，如果我将数据字段“drop”替换为“drops”，那么我会在列中得到逗号分隔的值，这意味着数组数据在那里，但不会创建dropdown

如果我在网格初始化之前创建了下拉适配器 //方法2

  var dropdownListStateAdapter3 = new $.jqx.dataAdapter(dropDownListStateSource3, { autoBind: true, async: false });

并按如下方式使用：

{ text: 'State', columntype: 'dropdownlist', datafield: 'revision_state', width: 55,
                        initeditor: function (row, cellvalue, editor) {
                                editor.jqxDropDownList({ displayMember: 'name', source: dropdownListStateAdapter3 });

然后我得到下拉列表，但我需要动态下拉列表，因为每一行都有不同的下拉值集。请让我知道如何使用方法1填充下拉列表

谢谢。

aynch:false和autobind:true需要添加到dataAdapter函数中

var dataAdapter_app = new $.jqx.dataAdapter(source_app,{
            loadComplete: function (record) {
              console.log(record);
                 datarecords = JSON.parse(JSON.stringify(record));
                 },
                 async:false,
                 autoBind:true
            });

这是我的解决方案

var merchantItems = [
{ name: 'ID', type: 'string' },
{ name: 'NAME', type: 'string' }
]

 jQuery(document).ready(function ($) {
        $.ajax({
            url: "/Parameter/GetMerchantList",
            type: "POST",
            success: function (e) {
                for (var i = 0; i < e.length; i++) {
                    if (e[i].NAME.trim() == "")
                        continue;
                    var mitem = {};
                    mitem.ID = e[i].ID;
                    mitem.NAME = e[i].NAME;
                    merchantItems.push(mitem);
                }
                merchantItems.splice(0,2);

                // initialize jqxGrid
                $("#jqxgridParameter").jqxGrid({
                    source: dataadapter,
                    width: $('.contentwrapper').width(),
                    height: 800,
                    selectionmode: 'singlerow',
                    theme: theme,
                    columnsresize: true,
