WP7 网格中 Canvas 之间的转换

发布于 2024-11-08 01:10:28 字数 1211 浏览 0 评论 0原文

我在网格中有两个画布，我想要转换全场景“图像”，我想知道如何在这两个画布控件之间进行转换。

我以编程方式将第一个画布添加到网格中，然后将第二个画布添加到网格中，并删除第一个画布，我真正想做的是它们之间的转换。

关于如何以编程方式实现这一目标有什么建议吗？

谢谢。

编辑：我已经实现了这个方法，但是遇到了问题，任何人都可以告诉我我是否使用错误？

     private void doTransitionIn(Canvas slide)
    {
        SlideTransition slideLeft = new SlideTransition();
        slideLeft.Mode = SlideTransitionMode.SlideDownFadeIn;

        ITransition transition = slideLeft.GetTransition(slide);

        transition.Completed += delegate { transition.Stop(); }; transition.Begin();
    }

    private void doTransitionOut(Canvas slide)
    {
        SlideTransition slideLeft = new SlideTransition();
        slideLeft.Mode = SlideTransitionMode.SlideDownFadeOut;

        ITransition transition = slideLeft.GetTransition(slide);
        transition.Completed += delegate { transition.Stop(); }; transition.Begin();
    }

这是我如何使用它：

            SceneGrid.Children.Add(nextCanvas);
            doTransitionIn(nextCanvas);
            doTransitionOut(currentCanvas);
            SceneGrid.Children.Remove(currentCanvas);

问题是动画仅似乎是从屏幕下方的一部分开始，我只看到它滑动了最后 20 个左右的像素，它并没有一直滑动。

I have two canvas's in a Grid, full scene "images" that I want to transition, I wonder how I would go about transitioning between these two Canvas controls.

Programatically I add the first canvas to the grid, then I add the second canvas to the grid, and remove the first, what I really want to do is transition between them.

Any suggestions on how I might achieve this programatically?

Thanks.

Edit: I have implemented this method, but am having problems, anyone able to tell me if I'm using it wrong?

     private void doTransitionIn(Canvas slide)
    {
        SlideTransition slideLeft = new SlideTransition();
        slideLeft.Mode = SlideTransitionMode.SlideDownFadeIn;

        ITransition transition = slideLeft.GetTransition(slide);

        transition.Completed += delegate { transition.Stop(); }; transition.Begin();
    }

    private void doTransitionOut(Canvas slide)
    {
        SlideTransition slideLeft = new SlideTransition();
        slideLeft.Mode = SlideTransitionMode.SlideDownFadeOut;

        ITransition transition = slideLeft.GetTransition(slide);
        transition.Completed += delegate { transition.Stop(); }; transition.Begin();
    }

And here is how I use it:

            SceneGrid.Children.Add(nextCanvas);
            doTransitionIn(nextCanvas);
            doTransitionOut(currentCanvas);
            SceneGrid.Children.Remove(currentCanvas);

The problem with this is that the animation only seems to start from part way down the screen, as in, i only see it slide the last 20 or so pixels, it doesn't slide all the way.

根据“过渡”的含义，我会考虑创建一个故事板来为每个画布的隐藏/显示设置动画。

我建议使用 TransitioningContentControl，它是 Silverlight Toolkit 的一部分。要使用此控件，请将您的第一个 Canvas 设为该控件的 Content。要进行转换，只需将 Content 更改为下一个 Canvas，然后 TransitioningContentControl 即可完成剩下的工作！

有许多博客文章提供了此控件的教程：
