在密码框的某些事件上显示密码字符 [英] showing password characters on some event for passwordbox

问题描述

我正在开发一个 Windows 手机应用程序.我要求用户登录.

I am developing a windows phone application.In that i ask the user to login.

在登录页面上，用户必须输入密码.

On the login page the user has to enter password.

现在我想要的是给用户一个复选框，选中时应显示密码字符.

Now what I want is that i give user a check box which when selected should show the characters of the password.

我没有在密码框上看到任何显示密码字符的属性.

I have not seen any property on password box to show password characters.

请建议一些方法来做到这一点.

Please suggest some way to do it.

推荐答案

不要认为 PasswordBox 可以实现...只是一个想法，但是您可以使用隐藏的 TextBox 并在用户单击CheckBox，你只需隐藏PasswordBox并显示TextBox；如果他再次点击，你会再次切换他们的可见性状态，依此类推...

Don't think that is possible with PasswordBox... just a thought, but you might accomplish the same result using a hidden TextBox and when the user clicks the CheckBox, you just hide the PasswordBox and show the TextBox; if he clicks again, you switch their Visibility state again, and so on...

这就是方法！

只需添加一个页面，将 ContentPanel 更改为 StackPanel 并添加此 XAML 代码:

Just add a page, change the ContentPanel to a StackPanel and add this XAML code:

<PasswordBox x:Name="MyPasswordBox" Password="{Binding Text, Mode=TwoWay, ElementName=MyTextBox}"/>
<TextBox x:Name="MyTextBox" Text="{Binding Password, Mode=TwoWay, ElementName=MyPasswordBox}" Visibility="Collapsed" />
<CheckBox x:Name="ShowPasswordCharsCheckBox" Content="Show password" Checked="ShowPasswordCharsCheckBox_Checked" Unchecked="ShowPasswordCharsCheckBox_Unchecked" />

接下来，在页面代码上，添加以下内容:

Next, on the page code, add the following:

private void ShowPasswordCharsCheckBox_Checked(object sender, RoutedEventArgs e)
{
    MyPasswordBox.Visibility = System.Windows.Visibility.Collapsed;
    MyTextBox.Visibility = System.Windows.Visibility.Visible;

    MyTextBox.Focus();
}

private void ShowPasswordCharsCheckBox_Unchecked(object sender, RoutedEventArgs e)
{
    MyPasswordBox.Visibility = System.Windows.Visibility.Visible;
    MyTextBox.Visibility = System.Windows.Visibility.Collapsed;

    MyPasswordBox.Focus();
}

这很好用，但如果再多做一些工作，您就可以完全使用 MVVM 了！

This works fine, but with a few more work, you can do this fully MVVM'ed!
