我想單擊它後禁用我的按鈕。我想看到它，但我不想點擊後再次點擊。 Windows Phone 8我該怎麼做？單擊後禁用按鈕

button1.isEnabled = false; //hide button.

我不想隱藏它，然後再次單擊它。

UIElement.IsHitTestVisible Property

獲取或設置聲明此元素是否可能被作爲命中測試

您可以在函數的開始設置your_btn.IsHitTestVisible = False，然後將其重置爲True返回的值在端

或

UIElement.IsEnabled Property

獲取或設置一個值，指示在用戶界面此元素是否啓用（UI）

使用的IsEnabled（即背景設置爲透明的），您可以創建一個樣式資源（去在XAML中，right click on the view of your_btn->edit template->edit a copy...，然後修改VisualState x:Name="Disabled"字段設置Storyboard.TargetProperty="Background" Value="your_background"。通過這種方式，你還可以模擬保持按鈕... 資源風格是

<Style x:Key="ButtonStyle1" TargetType="Button"> 
     <Setter Property="Background" Value="Transparent"/> 
     <Setter Property="BorderBrush" Value="{StaticResource PhoneForegroundBrush}"/> 
     <Setter Property="Foreground" Value="{StaticResource PhoneForegroundBrush}"/> 
     <Setter Property="BorderThickness" Value="{StaticResource PhoneBorderThickness}"/> 
     <Setter Property="FontFamily" Value="{StaticResource PhoneFontFamilySemiBold}"/> 
     <Setter Property="FontSize" Value="{StaticResource PhoneFontSizeMedium}"/> 
     <Setter Property="Padding" Value="10,5,10,6"/> 
     <Setter Property="Template"> 
      <Setter.Value> 
       <ControlTemplate TargetType="Button"> 
        <Grid Background="Transparent"> 
         <VisualStateManager.VisualStateGroups> 
          <VisualStateGroup x:Name="CommonStates"> 
           <VisualState x:Name="Normal"/> 
           <VisualState x:Name="MouseOver"/> 
           <VisualState x:Name="Pressed"> 
            <Storyboard> 
             <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Foreground" Storyboard.TargetName="ContentContainer"> 
              <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PhoneButtonBasePressedForegroundBrush}"/> 
             </ObjectAnimationUsingKeyFrames> 
             <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Background" Storyboard.TargetName="ButtonBackground"> 
              <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PhoneAccentBrush}"/> 
             </ObjectAnimationUsingKeyFrames> 
            </Storyboard> 
           </VisualState> 
           <VisualState x:Name="Disabled"> 
            <Storyboard> 
             <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Foreground" Storyboard.TargetName="ContentContainer"> 
              <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PhoneDisabledBrush}"/> 
             </ObjectAnimationUsingKeyFrames> 
             <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="BorderBrush" Storyboard.TargetName="ButtonBackground"> 
              <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PhoneDisabledBrush}"/> 
             </ObjectAnimationUsingKeyFrames> 
             <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Background" Storyboard.TargetName="ButtonBackground"> 
              <DiscreteObjectKeyFrame KeyTime="0" Value="Transparent"/> 
             </ObjectAnimationUsingKeyFrames> 
            </Storyboard> 
           </VisualState> 
          </VisualStateGroup> 
         </VisualStateManager.VisualStateGroups> 
         <Border x:Name="ButtonBackground" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" CornerRadius="0" Margin="{StaticResource PhoneTouchTargetOverhang}"> 
          <ContentControl x:Name="ContentContainer" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" Foreground="{TemplateBinding Foreground}" HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}" Padding="{TemplateBinding Padding}" VerticalContentAlignment="{TemplateBinding VerticalContentAlignment}"/> 
         </Border> 
        </Grid> 
       </ControlTemplate> 
      </Setter.Value> 
     </Setter> 
    </Style>

而且你的按鈕將有Style="{StaticResource ButtonStyle1}"財產

你有沒有試過把點擊事件這樣一行？

myButton.IsHitTestVisible = false;

從click事件退訂應該做的伎倆

試試這個 -

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

    //Then do what the button does. 
}

所以，第一次點擊之後，事件處理程序將從Click事件退訂。所以，沒有更多的點擊會調用事件處理程序。
