注意事项：------------------------------------------------------------------------------
1、在导出界面中重载
 C#   
          public   override   void   VerifyRenderingInServerForm(Control   control)   
          {   
                  //base.VerifyRenderingInServerForm(control);   
          }   
VB.net
  Public Overloads Overrides Sub VerifyRenderingInServerForm(ByVal control As Control)
    End Sub
 2、在web.config中修改   
  或在页面aspx中添加 EnableEventValidation="false"
