HTC到StoryBoard——DHTML迁移到WPF（二）

下载：https://files.cnblogs.com/civ3/storyBoard.rar

微软支持HTML组件技术HTC，但是安全和性能都有一定缺陷。在WPF中，利用StoryBoard可以快速实现一些以前需要用HTC才能较好实现的DHTML效果。
以下两个例子都很简单只是为了说明问题：
复用
DHTML:Style（+behavior）
WPF:Resource
形状
DHTML:VML的Shape，或DIV矩形
WPF:Rectangle
事件与行为
DHTML:Event.element用JS脚本
WPF:丰富的故事板特性

以下是源程序
DHTML

<html><head>
<style type="text/css">
.oStyle{
    behavior:url(storyBoard.htc);
    background-color:Blue;
}
</style>

<div style="width:100px; height:100px;" class="oStyle"></div>
