Code behind this
代码背后的这个
public partial class Window1 : Window
{
public Window1(String s)
{
InitializeComponent();
textblocknotify.Text = s;
Dispatcher.BeginInvoke(DispatcherPriority.ApplicationIdle, new Action(() =>
{
var workingArea = System.Windows.SystemParameters.WorkArea;
var transform = PresentationSource.FromVisual(this).CompositionTarget.TransformFromDevice;
var corner = transform.Transform(new Point(workingArea.Right, workingArea.Bottom));
this.Left = corner.X - this.ActualWidth - 10;
this.Top = corner.Y - this.ActualHeight-30;
}));
//this.Close();
}
private void Storyboard_Completed_1(object sender, EventArgs e)
{
this.Close();
}
private void Grid_MouseEnter_1(object sender, MouseEventArgs e)
{
//don't know what to do
}

You can use the PauseStoryboard Class and the UIElement.MouseEnter Event to pause a running Animation. Equally, if you want the Animation to resume when the mouse is no longer over the control, then you can use the ResumeStoryboard Class and the UIElement.MouseLeave Event. Here is a simple example to demonstrate:
您可以使用PauseStoryboard类和UIElement.MouseEnter事件来暂停正在运行的动画。同样，如果您希望在鼠标不再在控件上时恢复动画，则可以使用ResumeStoryboard类和UIElement.MouseLeave事件。这是一个简单的例子来演示：
<Button Content="Click Me">
<Button.Triggers>
<EventTrigger RoutedEvent="FrameworkElement.Loaded">
<BeginStoryboard Name="OpacityStoryboard">
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="(UIElement.Opacity)"
From="0" To="1" RepeatBehavior="Forever" AutoReverse="True" />
</Storyboard>
</BeginStoryboard>
</EventTrigger>
<EventTrigger RoutedEvent="UIElement.MouseEnter">
<PauseStoryboard BeginStoryboardName="OpacityStoryboard" />
</EventTrigger>
<EventTrigger RoutedEvent="UIElement.MouseLeave">
<ResumeStoryboard BeginStoryboardName="OpacityStoryboard" />
</EventTrigger>
</Button.Triggers>
</Button>
