extjs 3.4数据未从弹出网格显示到主网格

我有一个网格，我想在其中过滤一些结果。要过滤结果，将打开一个弹出窗口，用户可以选择搜索条件并过滤结果。php文件将被执行，结果将返回到弹出窗口，但它不会显示在主网格中。这是我的密码。 当用户选择单选按钮进行过滤时，此代码显示网格并显示结果：

var checkModel = new xg.CheckboxSelectionModel();

var orderGridPanel = {
    id: 'orderGridPanel',
    xtype: 'editorgrid',
    title: 'Orders',

    clicksToEdit: 2,
    frame: true,
    viewConfig: {
        forceFit:true
    },
    cm: new xg.ColumnModel({

            },
    columns: [

现在，当我单击搜索按钮时，此代码执行：

提前感谢。

如果希望网格显示数据，您需要将数据加载到网格的存储中。

origid设置在哪里？您能告诉我如何将数据分配给网格吗
