windows-8 - winrt 中带水印的密码框

Question

是否可以在 WinRt 中获取水印密码框？获取带水印的文本框没问题，但我不知道可以获取带水印的密码框的工具包。

我如何为自己实现一个？

Answer 1

看看WinRT XAML Toolkit .

他们还有

1. 水印文本框
2. 水印密码框

您可以自己实现自己的控件:

在.xaml中:

 <Border x:Name="brdPassword" Margin="5,0,5,10" BorderThickness="2" BorderBrush="White" CornerRadius="5" Grid.Row="0"
                                Background="White" Height="50" VerticalAlignment="Stretch">
                           <Grid>
                <TextBox x:Name="PasswordWatermark" TextWrapping="Wrap" 
                          Text="Watermark"  Foreground="#FFC4C4C4" IsHitTestVisible="False" 
                          Background="{x:Null}" BorderThickness="0" Padding="0,-10" 
                          FontSize="26.667" />
                 <PasswordBox x:Name="pbPassword" LostFocus="PasswordLostFocus"
                         GotFocus="PasswordGotFocus" Background="{x:Null}" 
                         FontSize="26.667" Margin="0,-12,0,-9" VerticalAlignment="Center"
                         BorderThickness="0" Opacity="0" />
                </Grid>
                </Border>

在.cs中

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

    private void CheckPasswordWatermark()
    {
        var passwordEmpty = string.IsNullOrEmpty(pbPassword.Password);
        PasswordWatermark.Opacity = passwordEmpty ? 100 : 0;
        pbPassword.Opacity = passwordEmpty ? 0 : 100;
    }

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