数据导出到Excel错误

Question

嗨我试图从数据导出到Excel工作表的数据，但有这个错误。

RegisterForEventValidation只能在渲染（）期间调用;

这里是我的代码

 Dim attachment As String 
     attachment = "attachment; filename=Contacts.xls" 
     Response.ClearContent() 
     Response.AddHeader("content-disposition", attachment) 
     Response.ContentType = "application/ms-excel" 
     Dim myStringWriter As New IO.StringWriter 
     Dim myhtmlStringWriter As New HtmlTextWriter(myStringWriter) 
     GridView1.RenderControl(myhtmlStringWriter) 
     Response.Write(myStringWriter.ToString) 
     Response.End() 

感谢

您可以在web.config文件中这样做，但在这种情况下，eventValidation将关闭所有的网页。

，或者你可以在Page指令将关闭验证单个页面做到这一点。
