How to fading out a wpf window during close

Hi mindstick!

I want to fade a window in/out in my application. Fading in occurs on Window.Loaded and I wanted to fade out on close (Window.Closed or Window.Closing). Fading in works perfectly but a RoutedEvent is not allowed on Window.Closing. What RoutedEvent should I be using for Close?

<Window.Triggers>

</Storyboard>

</BeginStoryboard>

</EventTrigger>

</Storyboard>

</BeginStoryboard>

</EventTrigger>

</Window.Triggers>

I get a error on , Value 'Window.Closing' cannot be assigned to property 'RoutedEvent'. Invalid event name.

thanks in advance

private bool closeStoryBoardCompleted = false;
private void Window_Closing(object sender, CancelEventArgs e)
{
    if (!closeStoryBoardCompleted)
    {
        closeStoryBoard.Begin();
        e.Cancel = true;
    }
}
private void closeStoryBoard_Completed(object sender, EventArgs e)
{
    closeStoryBoardCompleted = true;
    this.Close();
}

Can you answer this question?

Solution!

Closing is not a routed event, so you can't use it in an EventTrigger. Perhaps you could start the storyboard in the handler of the ClosingEvent in the code-behind and cancel the event... something like that :
