保留在回发口令字段值 [英] Retain Password Field Value on PostBack

问题描述

现在我有一个asp：精灵3步

Right now I have an asp:Wizard with 3 Steps.

1. 创建用户


2. 表格到电子邮件


3. 字段摘要

当被点击的第三步完成按钮，我想创建用户并发送的形式。我的逻辑是写，但我唯一的问题是pssed在向导时，下一步按钮是$ P $，发生回传，我的密码字段：

When the finish button is clicked on the third step I would like to Create the user and send the form. I have the logic for this written but the only problem I have is the when the next button is pressed on a wizard, a PostBack occurs and my password field:

<asp:TextBox ID="txtPassword" TextMode="Password" Width="70%" runat="server" />

不保留其值。

什么你会建议将是最安全的，实用的方法让我克服这个问题？

What would you suggest would be the most secure and practical method for me to overcome this problem?

推荐答案

我可能会开发一类重presenting将由向导创建的数据：

I would probably develop a class representing the data that will be created by the wizard:

public class WizardForm
{
    public User NewUser {get;set;}
    public Form FormToEmail {get;set;}
}

然后通过该向导的每一步我会更新这个类并将其存储在会话：

Then on each step through the wizard I'd update this class and store it in session:

WizardForm form = Session["WizardForm"] as WizardForm;
if (form == null)
{  
     form = new WizardForm();
     Session["WizardForm"] = form;
}

form.User.Password = txtPassword.Text; // etc

或者你可以只存储在会话密码，以后检索：

Or you could just store the password in Session and retrieve it later:

Session["WizardPassword"] = txtPassword.Text;
string password = Session["WizardPassword"].ToString();
