　　本文描述一种创建定制Web控件的容易方法，并把该控件使用于一个ASP.NET 2.0 web页面中显示微软DirectX图像转换过滤效果。

　　一、简介

　　本文描述一种创建定制web控件并应用于一个ASP.NET 2.0 web页面中显示微软DirectX图像转换过滤效果的容易的方法。文中包括一个拥有11个不同控件的类库，每一个控件分别展示微软DirectX图像转换过滤效果的某些方面。在这11个控件中，5个是页面过渡效果控件，其它的６个是用于增强文本外观的过滤效果控件。

　　在这6个用于增强文本外观的过滤效果控件中，每一个被实现为一个容器控件。这将允许用户或者直接把文本键入到该容器，或把一个标签放到该控件中并且把相应效果应用到这个标签上。选择使用一个标签控件的目的是为了提供一种容易的基于标准HTML的方法来实现调整大小、居中放置以及格式化文本。

　　剩下的5个控件用于在一个web页面中添加页面过渡效果而不用编写任何额外的HTML或VB代码。为了使用这些控件，用户仅需要把它们拖动到表单上。然而，这些控件没有相应的可视化组件，尽管页面能够被显示到浏览器中；当用户离开页面时，相应的过渡效果用于打开下一个页面。

　　相应于本文的示例工程中包含了一个简单的网站，含有单个default.aspx页面；该页面逐个展示上面的6个文本增强控件和一个页面过渡效果控件。

　　注意 本文中应用于演示工程和控件库的方法仅适用于Internet explorer，并没有针对其它浏览器类型提供支持。如果你在一家企业内网中工作并且你能够确保所有的用户都能够存取Internet explorer，那么这个控件集和这里的方法可能对你很有用。如果你公开地发布这些控件，那么，使用一个非Internet explorer浏览器冲浪的用户仍然能够读取相应的文本但是该效果将不存在。如果你确实想进行公开发布，那么你可以首先检查用户的浏览器并且如果它不是 IE的话，你应该建议他们最好使用IE来观看该站点。
