Question

Assume I have a button and I want the following behavior:

when I click on the button, it fires up an event – ok, that’s easy.

Now, if I click and wait, after a few seconds it suppose to fire up another event. e.g. popup a menu…

how to do that?

    DispatcherTimer PopupTimer = new DispatcherTimer();

    PopupTimer.Tick += new EventHandler(PopupTimerTick);
    PopupTimer.Interval = new TimeSpan(0, 0, 0, 0,5);


    private void PopupTimerTick(object sender, EventArgs e)
    {   
        if (Mouse.LeftButton == MouseButtonState.Pressed)
        {
            // If still pressed showing popup
            ((Storyboard)Resources["ShowPopup"]).Begin();
            PopupTimer.Stop();
        }
    }

    private void ImageOnMouseDown(object sender, MouseButtonEventArgs e)
    {
        PopupTimer.Start();
        e.Handled = true;
    }

    private void ImageOnMouseUp(object sender, MouseButtonEventArgs e)
    {
        e.Handled = true;

        if (Popup.IsOpen == false)
        {
            ((Storyboard)Resources["ShowPopup"]).Stop();
            // Here the operation that works on the click
        }
    }
