拖放行为消失了！ [英] Drag&Drop behavior disapeared!

问题描述

我刚开始使用Expression Blend& sketchFlow并遵循入门套件中的视频教程。

I just started using Expression Blend & sketchFlow and followed the video tutorial from the starter kit.

我注意到一个非常奇怪的问题，试图将拖放行为添加到列表框中。

I noticed a very strange problem trying to add a drag&drop behaviour to a list-box.

在视频中有15种行为，我需要使用的是拖放行为。

In the video there are 15 behaviors and the one I need to use is the drag&drop one.

在我的设置中，我只能看到13种行为，拖放行为缺少了！

On my setup I can see only 13 behaviors, the drag&drop one is missing!

这很奇怪而且非常可怕！

That's very strange and quite scary!

我甚至尝试过系统还原（使用Acronis true image恢复映像）到刚刚进行安装（干净安装），它没有帮助，仍有13种行为。

I even tried a system restore (image restore with Acronis true image) to the time when the install was just being made (a clean install), it didn't help, still 13 behaviors.

如何才能找回拖放行为？没有任何帮助，我也通过重新安装程序进行了修复（在我进行系统恢复之前），没有运气......

How can I get back the drag&drop behavior? nothing helps, i also did a repair through re-installing the program (before i did the system restore), no luck...

我几乎可以肯定我看到了拖放教程早期阶段的行为，但无法确定。

I'm almost sure I saw the drag&drop behavior during the early stages of the tutorial but cannot be sure about that.

我甚至检查了我的反病毒隔离区，没有任何内容...

I even checked my anti-virus quarantine, nothing there...

我在赢得XP sp2，P4-3ghz 1gb RAM。

I'm on win XP sp2, P4-3ghz 1gb RAM.

请帮助。
