Expression Blend:为什么我没有用于“过渡"和“缓和"的选项? [英] Expression Blend: Why do I not have options for Transitions and Easing?

问题描述

我正在将Expression Blend 4与.Net 3.5一起使用

I am using Expression Blend 4 with .Net 3.5

在下图中，提供了转场效果"选项以及为转场选择缓和效果"的功能:

In the image below, there are options for Transition Effects and the ability to choose Easing effects for your transitions:

我的Blend界面在我的WPF应用程序中没有这些内容:

My Blend interface does not have these on my WPF application:

但是，如果我创建一个新应用程序(例如WPF Sketchflow应用程序)，这些选项的显示方式将与第一张照片中的显示方式相同.

However, if I create a new application (such as a WPF Sketchflow app) these options appear just as they do in the first photo.

什么决定这些选项是否出现，以及如何将其放入WPF应用程序?

What determines whether or not these options appear, and how can I get them into my WPF application?

推荐答案

我认为您甚至需要WPF工具箱才能在.NET 3.5中达到这一目标. (WPF 3.5缺少VisualStateManager；该工具包添加了此缺失的部分.)至于为什么它没有显示出来，是因为它在WPF 3.5中不支持:

I think you need the WPF toolkit to even get this far with .NET 3.5. (WPF 3.5 lacks the VisualStateManager; the toolkit adds this missing piece.) As to why it doesn't show up, it's because it's not supported in WPF 3.5:

在V3中，我们在此区域添加了四个主要增强功能.第一个是 EasingFunctions，对于制作属性动画至关重要，它具有 正确的感觉.我们拥有所有经典作品-二次方，立方，弹跳， 弹性等.此外，您可以用C#或VB编写自己的EasingFunction 并将其应用于您想要的任何动画.这是所有受支持的 Silverlight 3和WPF 4.

In V3, we added four primary enhancements in this area. The first was EasingFunctions, which are critical to making property animations have the right feel. We’ve got all the classics—quadratics, cubics, bounce, elastic, etc. Plus, you can write your own EasingFunction in C# or VB and apply it to any animation you wish. This is all supported in Silverlight 3 and WPF 4.

在创建新的WPF Sketchflow应用时，几乎可以肯定它的目标是.NET 4.0.

When you create a new WPF Sketchflow app, it's almost certainly targeting .NET 4.0.
