目前的截图看不出具体问题，请参考截图建议，在 web.config 文件中配置 <customerErrors> 结点，再上传错误信息。
谢谢

我做了些测试发现如果不把 commandbar 上的其他项隐藏就不会出这个错误就是这个

protected override void Render(HtmlTextWriter writer)
   {
         WebControl update = FpSpread1.FindControl("Update") as WebControl;
         update.Visible = false;
         WebControl copy = FpSpread1.FindControl("Copy") as WebControl;
         copy.Visible = false;
         WebControl clear = FpSpread1.FindControl("Clear") as WebControl;
         clear.Visible = false;

         WebControl paste = FpSpread1.FindControl("Paste") as WebControl;
         paste.Visible = false;
         WebControl print = FpSpread1.FindControl("Print") as WebControl;
         print.Visible = true;

         WebControl cancel = FpSpread1.FindControl("Cancel") as WebControl;
         cancel.Visible = false;
         base.Render(writer);
   }

请修改为以下代码：

protected override void Render(HtmlTextWriter writer)
   {
         WebControl update = FpSpread1.FindControl("Update") as WebControl;
         if (update!=null)
            update.Visible = false;

         WebControl copy = FpSpread1.FindControl("Copy") as WebControl;
         if (copy!=null)
            copy.Visible = false;

         WebControl clear = FpSpread1.FindControl("Clear") as WebControl;
         if (clear!=null)
            clear.Visible = false;

         WebControl paste = FpSpread1.FindControl("Paste") as WebControl;
         if (paste!=null)
            paste.Visible = false;

         WebControl print = FpSpread1.FindControl("Print") as WebControl;
         if (print!=null)
            print.Visible = true;

         WebControl cancel = FpSpread1.FindControl("Cancel") as WebControl;
         if (cancel!=null)
            cancel.Visible = false;

         base.Render(writer);
   }
