數據導出到Excel錯誤

Question

嗨我試圖從數據導出到Excel工作表的數據，但有這個錯誤。

RegisterForEventValidation只能在渲染（）期間調用;

這裏是我的代碼

 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() 

感謝

您可以在web.config文件中這樣做，但在這種情況下，eventValidation將關閉所有的網頁。

，或者你可以在Page指令將關閉驗證單個頁面做到這一點。
