Gridview列到Excel

Question

我正在使用GridView來顯示數據。並且爲了將Gridview數據導出爲Excel格式，我使用了一個按鈕 - 「導出到Excel」。下載到Excel格式或 導出到Excel工作正常。該GridView總共顯示15列。

但是在excel文件中它只顯示了14列。可能是什麼問題？

試試這個編碼

按鈕點擊

  Response.Clear(); 
      Response.ContentType = "application/vnd.ms-excel"; 
      Response.Charset = ""; 
      Page.EnableViewState = false; 
      Response.AddHeader("Content-Disposition", "attachment;filename=report.xls"); 
      System.IO.StringWriter tw = new System.IO.StringWriter(); 
      System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(tw); 
      GridView1.RenderControl(hw); 
      Response.Write(tw.ToString()); 
      Response.End(); 

，並添加事件

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