グリッドビューを作成しようとしていますが、ハードコードされたデータを使用して正常に作成できます。

var store = Ext.create('Ext.data.Store', {
        storeId: 'myData',
        //url: 'GridViewController',
        fields: [
            { name: 'Q1', type: 'int' },
            { name: 'Q2', type: 'int' },
            { name: 'Q3', type: 'int' },
            { name: 'Q4', type: 'int' },
            { name: 'Q5', type: 'int' },
            { name: 'Improvements', type: 'string' },
            { name: 'Comments', type: 'string'}],
        data: { 'items': [
        { "Q1": "1", "Q2": "2", "Q3": "4", "Q4": "4", "Q5": "5", "Improvements": "Wut Is Up", "Comments": "Nothing" },
        { "Q1": "1", "Q2": "1", "Q3": "3", "Q4": "4", "Q5": "5", "Improvements": "Wut Is Up1", "Comments": "Nothing13"}]
        },
        proxy: {
            type: 'memory',
            //url: 'GridViewController'
            reader: {
                type: 'json',
                root: 'items'
            }
        }
    });

    //store.load();   
    this.grid = Ext.create('Ext.grid.Panel', {
        title: 'GridView App',
        store: Ext.data.StoreManager.lookup('myData'),
        columns: [
        //{ id: 'id', header: 'ID', width: 30,
        //    sortable: true, dataIndex: 'id'
        //},
        {header: 'Q1', width: 100, sortable: true, dataIndex: 'Q1' },
        { header: 'Q2', width: 100, sortable: true, dataIndex: 'Q2' },
        { header: 'Q3', width: 100, sortable: true, dataIndex: 'Q3' },
        { header: 'Q4', width: 100, sortable: true, dataIndex: 'Q4' },
        { header: 'Improvements', width: 200, sortable: true, dataIndex: 'Improvements' },
        { header: 'Comments', width: 200, sortable: true, dataIndex: 'Comments' }
    ],
        stripeRows: true,
        //height:250,
        width: 800,
        renderTo: Ext.getBody()
    });

これは正常に機能します...しかし、SQLデータベースからデータを取得してURLを使用したい... url：GridViewControllerのように（コードのように）...これが私のコントローラーです

public void GridViewController()
    {

        Response.Write("Survey Completed!");
        SqlConnection conn = DBTools.GetDBConnection("ApplicationServices2");
        string sqlquery = "Select Q1, Q2, Q3, Q4, Improvements, Comments FROM MyTable";
        SqlCommand cmd = new SqlCommand(sqlquery, conn);

        using (SqlDataReader reader = cmd.ExecuteReader())
        {
            while (reader.Read())
                //json.Add(reader.GetInt32(0), reader.GetString(1));
            reader.Close();
        }

        //cmd.Connection = conn;
        conn.Open();
        //cmd.ExecuteNonQuery();
        conn.Close();

    }

これをどのように実装するか迷っています。助けてください。どんな入力でも高く評価されます。
