'GridView'類型的控件'GridView1'必須放置在runat = server

的form標籤中。'GridView'類型的控件'GridView1'必須放置在runat = server的form標籤內。'GridView'類型的控件'GridView1'必須放置在runat = server

當我將Gridview導出到Excel時，出現這樣的錯誤。你可以幫我嗎？

我的代碼示例如下。

Dim SqlQuery As String = "SELECT * FROM vBasketbollTournamet ORDER BY 1 ASC" 

Dim cmd1 As New SqlCommand(SqlQuery, conn) 
Dim adp1 As New SqlDataAdapter(cmd1) 
adp1.Fill(dt2) 

GridView1.DataSource = dt2 
GridView1.DataBind() 


Dim oStringWriter As New StringWriter() 
Dim oHtmlTextWriter As New HtmlTextWriter(oStringWriter) 

GridView1.GridLines = GridLines.Horizontal 
GridView1.HeaderStyle.Font.Bold = True 
GridView1.RenderControl(oHtmlTextWriter) 

Response.Write(oStringWriter.ToString()) 
Response.[End]()

我想，你可以在下面的例子中使用。

.aspx文件中含量研究

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
<html xmlns="http://www.w3.org/1999/xhtml"> 
<head runat="server"> 
    <title></title> 
</head> 
<body> 
    <form id="form1" runat="server"> 
    <div> 
    </div> 
    <asp:GridView ID="GridView1" runat="server"> 
    </asp:GridView> 
    <br /> 
    <asp:Button ID="btntoExcel" runat="server" Text="GridView to Excel" onclick="btntoExcel_Click" /> 
    </form> 
</body> 
</html>

.aspx.vb文件內容
