Question

我在我的网格上使用PointerEntered和PointerExited来改变指针在里面时的颜色，有时（大部分时间）PointerExited不会在我的w10m手机上触发，我用断点检查它。与Poiner相同（Canceled / CaptureLost）。即使我在网格外触摸，当指针在外面100％时，它也不会触发。

任何想法如何解决？

我的代码（如果需要）：

        private void ButtonPointerEntered(object sender, PointerRoutedEventArgs e)
        {
            var c = (ButtonGrid.Background as SolidColorBrush).Color;
            ButtonGrid.Background = new SolidColorBrush(Color.FromArgb(60, c.R, c.G, c.B));
        }

        private void ButtonPointerExited(object sender, PointerRoutedEventArgs e) //Does not trigger
        {
            var c = (ButtonGrid.Background as SolidColorBrush).Color;
            ButtonGrid.Background = new SolidColorBrush(Color.FromArgb(0, c.R, c.G, c.B));
        }

XAML：

            <Grid PointerEntered="ButtonPointerEntered" Tapped="ButtonTapped"  x:Name="ButtonGrid" Background="{ThemeResource ApplicationForegroundThemeBrush}" PointerExited="ButtonPointerExited">
                <Grid.RowDefinitions>
                    <RowDefinition Height="auto"/>
                    <RowDefinition/>
                </Grid.RowDefinitions>
                <TextBlock x:Name="IconTB" FontFamily="Segoe MDL2 Assets" FontSize="18" HorizontalAlignment="Center" VerticalAlignment="Top" Margin="0,3,0,0"/>
                <TextBlock x:Name="TextTB" Grid.Row="1"  FontSize="13" HorizontalAlignment="Center" TextWrapping="WrapWholeWords" TextAlignment="Center" Margin="0,0,0,2"/>
            </Grid>

我启动了我的应用程序而没有使用visual studio进行调试......它的工作正常100％。所以问题在于调试

Windows 10 UWP PointerExited不会在触摸屏上触发
