Question

如何在Windows Phone中显示带提示文字的密码框？

我尝试了PasswordBox和Toolkit's PhoneTextBox。将这两者结合起来有什么特别之处吗？

Answer 1

为此，我现在正在使用http://damianblog.com/2011/01/21/wp7-password-watermark/。我希望能有更好的方法。

Answer 2

另一种选择：WindowsPhoneControls

此外，Telerik WP控件的下一个版本还有一个RadPasswordTextBox。

Answer 3

也许，尝试编辑phonetextbox的控件模板。用passwordbox替换文本框。

你可以获得一个密码盒版手机文本框，LOL

Answer 4

您可以创建自己的WatermarkedPasswordBox，它将从PasswordBox传递。这并不困难。此链接将为您提供帮助：

Answer 5

在使用Windows Phone Toolkit

的Windows Phone 8中

恩Xaml

<Grid Grid.Row="1" Margin="12,0,0,0" x:Name="ContentPanel">             
        <toolkit:PhoneTextBox Height="72" Margin="0,0,0,270" TextWrapping="Wrap"  VerticalAlignment="Bottom" Hint="{Binding LocalizedResources.LblUser, Source={StaticResource LocalizedStrings}}" x:Name="txtUser" />
        <toolkit:PhoneTextBox Height="72" Margin="0,0,0,210" TextWrapping="Wrap" Hint="{Binding LocalizedResources.LblPassword, Source={StaticResource LocalizedStrings}}" x:Name="txtPasswordPlace" VerticalAlignment="Bottom" IsReadOnly="True" />            
        <PasswordBox Margin="0,72,0,210" VerticalAlignment="Bottom" x:Name="txtPassword" LostFocus="PasswordLostFocus" GotFocus="PasswordGotFocus" Opacity="0"/>
        <Button x:Name="btnLogin" Content="{Binding LocalizedResources.LblStartSession, Source={StaticResource LocalizedStrings}}" Click="BtnLogin_Click" VerticalAlignment="Bottom" Margin="0,0,0,150" />            
    </Grid

En C＃

    public void CheckPasswordWatermark()
    {
        var passwordEmpty = string.IsNullOrEmpty(txtPassword.Password);
        txtPasswordPlace.Opacity = passwordEmpty ? 100 : 0;
        txtPassword.Opacity = passwordEmpty ? 0 : 100;
    }

    private void PasswordGotFocus(object sender, RoutedEventArgs e)
    {
        txtPasswordPlace.Opacity = 0;
        txtPassword.Opacity = 100;
    }

    private void PasswordLostFocus(object sender, RoutedEventArgs e)
    {
        CheckPasswordWatermark();
    }
