ボタンのクリックで GridPanel を読み込もうとすると、javascript エラーが発生します。page_load イベントの呼び出し中に同じ関数が機能しています。

コード：

    private DataTable GetDataTable()
    {
       DataTable table = new DataTable();

       table.Columns.AddRange(new DataColumn[] {
           new DataColumn("Company")   { ColumnName = "Company",    DataType =        typeof(string) },
           new DataColumn("Price")     { ColumnName = "Price",      DataType =    typeof(double) },
           new DataColumn("Change")    { ColumnName = "Change",     DataType =  typeof(double) },
           new DataColumn("PctChange") { ColumnName = "PctChange",  DataType = typeof(double) },
           new DataColumn("PctChange") { ColumnName = "LastChange", DataType = typeof(DateTime) }
       });

       foreach (object[] obj in this.Data)
       {
           table.Rows.Add(obj);
       }

       return table;
    }

    private object[] Data
    {
       get
       {
           DateTime now = DateTime.Now;

           return new object[]

デザイナー ビュー:

        <ext:Button runat="server" ID="btnSearch" Text="Search" Icon="FeedMagnify" X="150"
               Y="10">
               <DirectEvents>
                   <Click OnEvent="btnSearch_Click" />
               </DirectEvents>
           </ext:Button>

page_load で createDynamicGrid() を呼び出している場合、正常に動作しています。

エラー メッセージ:「Microsoft JScript コンパイル エラー: 予期される識別子」
