watermarked PasswordBox in winrt

问题

is it possible to get a watermarks passwordbox in WinRt? It is no problem to get a textbox with a watermark, but I don't know a toolkit where I can get a password box with a watermark.

How can I implement one for myself?

回答1:

Take a look on WinRT XAML Toolkit.

They also have

WatermarkTextBox
WatermarkPasswordBox

By yourself you can implement your own controls:

in .xaml:

 <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>

in .cs

    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;
    }

Hope it's help

I don't think we can put watermark in the Password control. You can put a TextBox with wartermark in the same row and same column with the Password control, then handle the two controls' GotFocus and LostFocus events to make the control Visible or Collapsed.

There is no toolkit yet which provides watermarked password box. However this may help:-
