我是一名新的 ASP.NET 开发人员,我正在为我的公司开发一个基于 Web 的建议框程序,员工可以在其中提交他们有的任何安全建议。现在,我正在研究这个系统的管理部分。

管理员将能够使用所有者的用户名查看 GridView 控件中列出的所有建议。在 GridView 的最后一列中,将在此处列出状态。当管理员单击其中一个建议的状态时,将出现一个新的弹出窗口 (asp.net ajax ModalPopUpExtender),其中列出所有可能的状态,例如:已执行、已批准...等。当管理员选择其中一种状态,建议的状态将在数据库中更新。一切正常。我现在要做的是,当用户更新任何建议的状态时,将向所有者发送一封关于他的建议状态更新的电子邮件通知。我已经编写了 Mail 功能,但我不知道如何获取所选建议的用户名,表明其状态已更新。谁能帮我解决这个问题?

我真的很难获得更新建议的用户名。

仅供参考,我有以下数据库设计:

Employee Table: Username, Name...
SafetySuggestionsLog: ID, Title, Description, Username, StatusID
SafetySuggestionsStatus: ID, Status

ASP.NET 代码:

从表 SafetySuggestionsLog 通过用户名获取用户

string sqlGetLog = string.format("select * from SafetySuggestionsLog where SafetySuggestionsID= {0}", Convert.ToInt32(HiddenField1.Value));

然后在您获得 SafetySuggestionsLog 项目/记录后,您获取用户名并使用它来获取用户对象

string userName = SafetySuggestionsLog.UserName; (just get the name from your returned record)

    string sqlGetUser = string.format("select * from Employee where UserName= '{0}'", userName);
