我有一個問題，我的dataGridVew'GridView'類型的控件'GridView1'必須放置在runat = server的窗體標籤中。

我試圖將數據從我的數據庫中導出到Excel FIE

它是一個小頁面，只有數據網格視圖和按鈕導出這樣的：

<html xmlns="http://www.w3.org/1999/xhtml"> 
<head runat="server"> 
<title></title> 
</head> 
<body> 
<form id="form1" runat="server">

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click 
    Response.Clear() 
    Response.Buffer = True 
    Response.ContentType = "application/vnd.ms-excel" 
    Response.Charset = "" 

    Me.EnableViewState = False 
    Dim oStringWriter As New System.IO.StringWriter() 


    Dim oHtmlTextWriter As New System.Web.UI.HtmlTextWriter(oStringWriter) 


    'render html content to textwriter 
    GridView1.RenderControl(oHtmlTextWriter) 
    Response.Write(oStringWriter.ToString()) 
    Response.[End]() 

End Sub

當我按一下按鈕錯誤消息來：「控制「GridVi 'GridView'類型的'ew1'必須放置在runat = server的表單標籤中。???「即使我已經把它放在形式？

只寫這個方法：

public override void VerifyRenderingInServerForm(Control control) 
{ 
    /* Verifies that the control is rendered */ 
}

此錯誤，當您使用實體框架綁定數據網格也會發生。改爲使用datatable。
