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

when i click on the button error message is coming : "Control 'GridView1' of type 'GridView' must be placed inside a form tag with runat=server.???" 当我点击按钮时出现错误信息：“类型'GridView'的控件'GridView1'必须放在带有runat = server的表单标签内。” even i have placed it in form ??? 即使我把它放在形式???

Just Write this Method: 只需编写此方法： 

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

Simply add this to your page 只需将其添加到您的页面即可 

public override void VerifyRenderingInServerForm(Control control)
{
  /* Confirms that an HtmlForm control is rendered for the specified ASP.NET
 server control at run time. */
}

And put EnableEventValidation="false" 并把EnableEventValidation =“false”

You can find it here 你可以在这里找到它

GridView must be placed inside a form tag with runat="server" even after the GridView is within a form tag 即使GridView在表单标记内，GridView也必须放在带有runat =“server”的表单标记内

RegisterForEventValidation can only be called during Render RegisterForEventValidation只能在渲染期间调用

This error also occurs when you bind datagrid using ENTITY FRAMEWORK. 使用ENTITY FRAMEWORK绑定数据网格时也会发生此错误。 Use datatable instead. 请改用数据表。
