c# - 导出到 excel 的 RadGrid telerik 问题

Question

我在我的 MasterTableView 中添加了以下行:

<CommandItemSettings ShowExportToWordButton="true" ShowExportToExcelButton="true" ShowExportToCsvButton="true" />

但是当我点击它时，会出现正在加载的 div，然后刷新网格上的数据，没有其他任何事情发生。没有“保存文件”窗口。

我错过了什么吗？

在Grid前添加如下代码:

<script type="text/javascript">
        function onRequestStart(sender, args)
        {
            if (args.get_eventTarget().indexOf("ExportToExcelButton") >= 0 ||
                    args.get_eventTarget().indexOf("ExportToWordButton") >= 0 ||
                    args.get_eventTarget().indexOf("ExportToCsvButton") >= 0)
            {
                args.set_enableAjax(false);
            }
        }
    </script>

    <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
        <ClientEvents OnRequestStart="onRequestStart" />
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="RadGrid1">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="RadGrid1" />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
    </telerik:RadAjaxManager>

后面的代码添加下面的代码:

protected void RadGrid1_ItemCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)
{
    if (e.CommandName == Telerik.Web.UI.RadGrid.ExportToExcelCommandName ||
            e.CommandName == Telerik.Web.UI.RadGrid.ExportToWordCommandName ||
            e.CommandName == Telerik.Web.UI.RadGrid.ExportToPdfCommandName ||
            e.CommandName == Telerik.Web.UI.RadGrid.ExportToCsvCommandName)
    {
        gridResult.ExportSettings.IgnorePaging = true;
        gridResult.ExportSettings.OpenInNewWindow = true;
        if (e.CommandName == Telerik.Web.UI.RadGrid.ExportToExcelCommandName)
            gridResult.MasterTableView.ExportToExcel();
        else if (e.CommandName == Telerik.Web.UI.RadGrid.ExportToWordCommandName)
            gridResult.MasterTableView.ExportToWord();
        else if (e.CommandName == Telerik.Web.UI.RadGrid.ExportToCsvCommandName)
            gridResult.MasterTableView.ExportToCSV();
        else if (e.CommandName == Telerik.Web.UI.RadGrid.ExportToPdfCommandName)
            gridResult.MasterTableView.ExportToPdf();

    }
}
