如何从asp.net C＃Web窗体应用程序中的GridView中将selectedrow单元格值获取到电子邮件正文中？

Question

我想从指定的gridviews的选定行中获取单元格值，并在电子邮件正文中使用这些值。 电子邮件已送达，但没有在电子邮件正文中包含单元格值，而是具有“ System.Web.UI.WebControls.HiddenField”。 这是我用于电子邮件正文的代码：

msg.Body = "A review for document number " + gv_vendor_doc.SelectedRow.Cells[1].Text + " " + "titled " + gv_vendor_doc.SelectedRow.Cells[3].Text + " " + "for vendor " + gv_vendor_list.SelectedRow.Cells[2].Text + " " + "has been submitted for your review.";

当我在本地主机上运行时，以上代码按预期工作，但在生产Web服务器上尝试时，则未按预期工作。 任何帮助将不胜感激。

这是一个asp.net c＃Web窗体应用程序。

谢谢，J

这是gridview：

我从服务器上删除了所有文件，然后将它们移回，一切开始正常工作。 谢谢您的帮助。
