你还在使用2.X吗？CKEditor 3.6界面效果很漂亮，功能强大，配置也简单，下面我来介绍一下配置方法：
1.首先到http://ckeditor.com/download官方网站下载最新的CKEditor ，目前的最新版是3.61，下载 CKEditor for ASP.NET。下载完成后，解压压缩包，可以看到提供的例子和bin目录，还有_Samples文件夹。
2.打开你的项目，把_Samples文件夹下的ckeditor文件夹copy到你的项目里面，然后添加引用，寻找到 bin目录下的Release文件夹下的CKEditor.NET.dll，添加引用。
3.在配置文件中添加
        <system.web>
  <pages>
   <controls>
    <add tagPrefix="CKEditor" assembly="CKEditor.NET" namespace="CKEditor.NET"/>
   </controls>
  </pages>
 </system.web>
3.在应用到ckeditor的页面引入
<%@Register Assembly="CKEditor.NET" Namespace="CKEditor.NET" TagPrefix="CKEditor"%>
4.在需要用到ckeditor的地方加入
<CKEditor:CKEditorControl ID="CKEditor1" runat="server"></CKEditor:CKEditorControl>
改变颜色：
 <CKEditor:CKEditorControl ID="dataContent" runat="server" UIColor="#4e72b8" Language="de" EnterMode="BR">
 </CKEditor:CKEditorControl>
修改 UIColor的颜色代码值就可以自定义控件的颜色，效果很好看！
 If you want use the CKEditor for ASP.NET Control, you must add references to the project and register the control.
 If you only intend to use the control on a single page, you can add a Register section to its source code:
<%@Register Assembly="CKEditor.NET" Namespace="CKEditor.NET" TagPrefix="CKEditor"%>
 If you intend to use the control on multiple pages, you can add the Register section in web.config. Insert the following code into the <system.web><pages><controls> section:
<add tagPrefix="CKEditor" assembly="CKEditor.NET" namespace="CKEditor.NET"/>
 To insert the CKEditor for ASP.NET Control into a web page, use the following code:
<CKEditor:CKEditorControl ID="CKEditor1" runat="server"></CKEditor:CKEditorControl>
