按鈕點擊不解僱首次的[Windows 8.1/10平板電腦僅]

我寫一個樣本窗口通用的應用程序與3狀態按鈕（普通，重點和按下）按鈕點擊不解僱首次的[Windows 8.1/10平板電腦僅]

我的代碼如下。

現在我正面臨一個按鈕點擊的問題，當第一次點擊按鈕時，按鈕點擊事件不會被解僱。但第一次點擊之後，它工作正常[問題是Windows平板僅發生，工作在臺式機和筆記本電腦精]

這是衆所周知的問題，或任何東西錯的是我的代碼

public sealed partial class MainPage : Page 
{ 
    public MainPage() 
    { 
     this.InitializeComponent(); 
    } 

    private void ButtonClicked(object sender, RoutedEventArgs e) 
    { 
     System.Diagnostics.Debug.WriteLine("Inside Button clicked:Button"); 
    } 

    private void ImageClicked(object sender, RoutedEventArgs e) 
    { 
     System.Diagnostics.Debug.WriteLine("Inside Image clicked:CustomButton"); 
    } 
}

XAML

集[clickmode]（https://msdn.microsoft.com/en-us/library/windows/apps/windows.ui.xaml.controls.clickmode）=按下的按鈕。 –

我們試過了。但沒有按預期工作。 –

真的嗎？嗯，沒想到的是，將不得不稍後再回頭看看，對此感到遺憾。 –

刪除了ObjectAnimationUsingKeyFrames標籤並使用了DoubleAnimation標籤。還將目標屬性Source更改爲Opactity。然後用指定的持續時間更新圖像。

<VisualState x:Name="Normal"> 
    <Storyboard> 
    <DoubleAnimation Duration="0" To="1" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="NormalButton"/> 
    </Storyboard> 
</VisualState>
