Windows Phone 7的导航动画 [英] Windows Phone 7 Navigation Animation

问题描述

我试图做从页面导航离开时的动画，但我得到这个错误：

I'm trying to do an animation when navigating away from a page, but I get this error:

指定对象上无法解析TargetProperty（UIElement.RenderTransform）。（CompositeTransform.TranslateX）。

Cannot resolve TargetProperty (UIElement.RenderTransform).(CompositeTransform.TranslateX) on specified object.

我复制了code从一本书，我测试了本书的样本code和它的作品，但我不能让它在我的应用程序工作。有任何想法吗？这是我的code：

I copied the code from a book, and I tested the book's sample code and it works but I can't get it to work on my app. Any ideas? This is my code:

XAML：

<phone:PhoneApplicationPage.Resources>
        <Storyboard x:Name="HidePage" Completed="HidePage_Completed">
            <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(CompositeTransform.TranslateX)" Storyboard.TargetName="phoneApplicationPage">
                <EasingDoubleKeyFrame KeyTime="0" Value="0"/>
                <EasingDoubleKeyFrame KeyTime="0:0:1" Value="-480"/>
            </DoubleAnimationUsingKeyFrames>
            <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(CompositeTransform.TranslateY)" Storyboard.TargetName="phoneApplicationPage">
                <EasingDoubleKeyFrame KeyTime="0" Value="0"/>
                <EasingDoubleKeyFrame KeyTime="0:0:1" Value="-800"/>
            </DoubleAnimationUsingKeyFrames>
        </Storyboard>
<phone:PhoneApplicationPage.Resources>

C＃

protected override void OnNavigatingFrom(NavigatingCancelEventArgs e)
{
    base.OnNavigatingFrom(e);

    if (this.UriToNavigateTo == null)
    {
        e.Cancel = true;
        UriToNavigateTo = e.Uri;
        this.HidePage.Begin();
    }
    else
    {
        UriToNavigateTo = null;
    }
}

谢谢！

推荐答案

您忘了设置CompositeTransform对象，界定什么你正在使用一种变换。

You forgot to set the CompositeTransform object, which define what kind of transform you are using.

<phone:PhoneApplicationPage.RenderTransform>
    <CompositeTransform/>
</phone:PhoneApplicationPage.RenderTransform>
