如何在Windows Phone中显示带有提示文本的密码框？

我尝试了PasswordBox和Toolkit's PhoneTextBox，但需要进行特殊处理以将两者结合起来吗？

另一个选项：WindowsPhoneControls

此外，Telerik WP控件的下一个版本将具有RadPasswordTextBox。

在 Windows Phone 8 中使用 Windows Phone Toolkit

在 Xaml 中

<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

在C#中

    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();
    }

编程愉快！

也许，尝试编辑phonetextbox的控件模板。用passwordbox替换文本框。
这样你就可以得到一个密码框版本的phonetextbox，哈哈。
