我试图让我的游戏结束时出现一个文本框与获胜者。我使用text属性上的触发器执行此操作,该触发器将可见性设置为在其为空时折叠。接下来,我尝试在此文本框中添加边框。然而,当我的文本框被折叠时(所以当游戏仍在进行时),文本框像以前一样不可见,但边框已经在屏幕上显示为一个小黑框。
是否有人知道如何隐藏边框,直到它包含的文本框不为空?
提前致谢。

当TextBlock折叠时,您可以使用以下技巧折叠边框:
<Border Canvas.Left="160"
Canvas.Top="225"
Background="White"
BorderBrush="Black"
BorderThickness="2"
Canvas.ZIndex="2"
Visibility="{Binding Visibility,
ElementName=myTextBlock}">
<TextBlock x:Name="myTextBlock"
FontFamily="Helvetica"
FontSize="20"
FontWeight="Bold"
Foreground="{Binding WinnerPopup.Value,
Converter={StaticResource ownerConverter}}"
Padding="15"
Text="{Binding WinnerPopup.Value}">
<TextBlock.Style>
<Style TargetType="TextBlock">
<Style.Triggers>
<Trigger Property="Text" Value="">
<Setter Property="Visibility" Value="Collapsed" />
</Trigger>
</Style.Triggers>
</Style>
</TextBlock.Style>
</TextBlock>
</Border>
