我想在点击后禁用我的按钮。我想看到它，但我不想在点击后再次点击。在 Windows Phone 8 中，我该怎么做？

button1.isEnabled = false; //hide button.

我不想隐藏它并再次单击它。

UIElement.IsHitTestVisible Property

获取或设置一个值，该值声明此元素是否可以作为命中测试返回

您可以your_btn.IsHitTestVisible = False在函数的开头设置，然后将其重置为True结尾

或者

UIElement.IsEnabled Property

获取或设置一个值，该值指示是否在用户界面 (UI) 中启用此元素

使用 IsEnabled （将背景设置为透明），您可以创建样式资源（在 XAML 中right click on the view of your_btn->edit template->edit a copy...，然后修改VisualState x:Name="Disabled"字段设置Storyboard.TargetProperty="Background" Value="your_background"。通过这种方式，您还可以模拟一个按住按钮...资源样式是

 <Style x:Key="ButtonStyle1" TargetType="Button">
        <Setter Property="Background" Value="Transparent"/>
        <Setter Property="BorderBrush" Value="{StaticResource PhoneForegroundBrush}"/>
        <Setter Property="Foreground" Value="{StaticResource PhoneForegroundBrush}"/>

                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

你的按钮将具有Style="{StaticResource ButtonStyle1}"属性

您是否尝试过在 Click Event 中添加这样一行？

myButton.IsHitTestVisible = false;

取消订阅点击事件应该可以解决问题

尝试这个 -

private void button1_Click(object sender, RoutedEventArgs e)
{    
    button1.Click -= button1_Click;

    //Then do what the button does.   
}

因此，在第一次单击之后，事件处理程序将取消订阅 Click Event。因此，没有进一步的点击将调用事件处理程序。
