Question

我有一个gridvidew（GV2）。我希望用户能够将此gridview的内容导出到Excel电子表格以进行离线处理。

这是我的子程序：

Protected Sub ExcelButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ExcelButton.Click
        Response.ContentType = "application/vnd.ms-excel"
        Response.Charset = ""
        Me.EnableViewState = False
        Dim stringWriter As New System.IO.StringWriter()
        Dim htmlWriter As New System.Web.UI.HtmlTextWriter(stringWriter)
        GV2.RenderControl(htmlWriter)
        Response.Write(stringWriter.ToString())
        Response.End()
    End Sub

单击ExcelButton时出现错误消息：

“GridView”类型的控件“GV2”必须放在带有runat = server的表单标记内。

控件GV2实际上在里面：

 <form id="form1" runat="server"></form>

Answer 1

此错误消息后面有一个“story”。我会直接找到其中一个解决方案。

将此添加到ASPX文件的代码隐藏：

Public Overrides Sub VerifyRenderingInServerForm(control As Control)

End Sub
