如何在WPF中使用Frame控件进行过渡效果？

Question

我觉得这很容易,但我猜不是.

我有两页加载到我的帧控件中.我希望能够从一个页面到下一个页面具有漂亮的幻灯片效果,或者只是一个简单的淡入效果.

似乎无法在互联网上的任何地方找到它.

此处讨论了类似的问题:导航到页面时的过渡淡化动画使用此处描述的技术,您可以在每次导航新页面时滑动\移动帧控件.像这样的Smth:

XAML:

...
<Frame Name = "frame" Navigating="frame_Navigating">
...

码:

...
private bool                        _allowDirectNavigation = false;
private NavigatingCancelEventArgs   _navArgs = null;
private Duration                    _duration = new Duration(TimeSpan.FromSeconds(1));
private double                      _oldHeight = 0;

private void frame_Navigating(object sender, NavigatingCancelEventArgs e)
{
    if (Content!=null && !_allowDirectNavigation)
    {
        e.Cancel = true;

        _navArgs = e;
        _oldHeight = frame.ActualHeight;

        DoubleAnimation animation0 = new DoubleAnimation();
        animation0.From = frame.ActualHeight;
        animation0.To = 0;
        animation0.Duration = _duration;
        animation0.Completed += SlideCompleted;
        frame.BeginAnimation(HeightProperty, animation0);
    }
    _allowDirectNavigation = false;
}

private void SlideCompleted(object sender, EventArgs e)
{
    _allowDirectNavigation = true;
    switch (_navArgs.NavigationMode)
    {
        case NavigationMode.New:
            if (_navArgs.Uri == null)
                frame.Navigate(_navArgs.Content);
            else
                frame.Navigate(_navArgs.Uri);
            break;
        case NavigationMode.Back:
            frame.GoBack();
            break;
        case NavigationMode.Forward:
            frame.GoForward();
            break;
        case NavigationMode.Refresh:
            frame.Refresh();
            break;
    }

    Dispatcher.BeginInvoke(DispatcherPriority.Loaded,
        (ThreadStart)delegate()
        {
            DoubleAnimation animation0 = new DoubleAnimation();
            animation0.From = 0;
            animation0.To = _oldHeight;
            animation0.Duration = _duration;
            frame.BeginAnimation(HeightProperty, animation0);
        });
}
...

希望这有帮助,问候

我的答案是serge_gebunko给出的答案的改进版本.
它为您提供滑动左右效果.

XAML

...
<Frame Name = "MainFrame" Navigating="MainFrame_OnNavigating">
...

C#

 private void MainFrame_OnNavigating(object sender, NavigatingCancelEventArgs e) {
                var ta = new ThicknessAnimation();
                ta.Duration = TimeSpan.FromSeconds(0.3);
                ta.DecelerationRatio = 0.7;
                ta.To = new Thickness(0 , 0 , 0 , 0);
                if (e.NavigationMode == NavigationMode.New) {         
                    ta.From = new Thickness(500, 0, 0, 0);                                                  
                }
                else if (e.NavigationMode == NavigationMode.Back) {                
                    ta.From = new Thickness(0 , 0 , 500 , 0);                                               
                }
                 (e.Content as Page).BeginAnimation(MarginProperty , ta);
            }
