Question

可以从Silverlight Toolkit中获取TransitioningContentControl的Transition属性的可能值是什么？

该属性是字符串类型。即使在silverlight工具包官方网站上，我也没有找到任何答案。

Answer 1

您的选择是：

DefaultTransition
正常
UpTransition
DownTransition

我是如何发现的：

我的VisualStudio ObjectBrowser-Window告诉了我关于TransitioningContentControl：

的内容

public string Transition {set;得到; }       System.Windows.Controls.TransitioningContentControl
的成员
摘要：获取或设置要使用的转换的名称。这些   直接对应于PresentationStates中的VisualStates   基。

和

public const string DefaultTransitionState       System.Windows.Controls.TransitioningContentControl
的成员
摘要：表示默认转换的状态名称。

什么打开Blend中的默认模板告诉我有关PresentationStates组的信息...等一下......加载混合...继续崩溃...我讨厌Blend ...现在我明白了：

<Style x:Key="TransitioningContentControlDefaultStyle" TargetType="TransitioningContentControl">
        <Setter Property="IsTabStop" Value="True"/>
