增加3个控件。HTML Editor, ComboBox, and ColorPicker. 下载地址：http://ajaxcontroltoolkit.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=27326。
下面是介绍信息。
- HTMLEditor
The HTMLEditor control allows you to easily create and edit HTML content. You can edit in design mode, as a rich text editor, or in source view to edit the HTML markup directly.

- ComboBox
The ComboBox control provides a DropDownList of items, combined with TextBox. Different modes determine the interplay between the text entry and the list of items.
Many thanks to Dan Ludwig for building this.
与一般DropDownList 不同的是他可以输入文字，输入选项的前几个字可以匹配符合条件的选项，还可以在Textbox里输入新选项。
- ColorPicker
The ColorPicker Control Extender can be attached to any ASP.NET TextBox control. It provides client-side color-picking functionality with UI in a popup control.
Many thanks to Alexander Turlov for building this.
输入十六进制颜色代码可以显示出对应的颜色，选择了颜色也可以显示对应的代码。
