如何将会话值从aspx页面传输到母版页 [英] How to transfer session values from aspx page to master page

问题描述

我想在我的网络应用程序中显示为欢迎并登录用户名。

I would like to display as Welcome and logged in username in my web application.

推荐答案

没什么可做的......只需指定用户名文本框值到登录页面中的Session变量并将该Session变量访问到母版页：



登录页面：

Nothing to do more....Just assign the username textbox value to the Session variable in the login page and access that Session variable to the master page:

Login page:

   DataTable dt = Check username in the database and put in a datatable
   if (dt != null && dt.Rows.Count > 0)
 {
      Session["UserName"] = txtUserName.Text.Trim();

      Response.Redirect("/Home.aspx");

}
   else
   {
        lblMsg.Text = "username or password invalid";
   }

在母版页中：

In the master page:

if (Session["UserName"] != null)
                    lblWelcome.Text = "Welcome " + Session["UserName"].ToString();
                else
                    lblWelcome.Text = "Welcome Guest"

请阅读我对该问题的评论。



我建议从这里开始：如何：在ASP之间传递值.NET网页 [ ^ ] + 将会话变量从ContentPage传递到MasterPage的控件 [ ^ ]。

Please read my comment to the question.

I'd suggest to start here: How to: Pass Values Between ASP.NET Web Pages[^] + passing Session variables from ContentPage to MasterPage's Control[^].
