在 ASP.NET MVC 3 中应用 KindEditor

http://www.cnblogs.com/weicong/archive/2012/03/31/2427608.html

第一步

将 KindEditor 的源文件添加到项目中，建议放到 /Scripts/kindeditor 目录中，其中只需要有 lang目录、plugis目录、themes目录和kindeditor-min.js文件即可。

第二步

在 /Views/Shared/EditorTemplates 目录中添加一个分部视图“kindeditor.cshtml”(文件名可任意)。代码如下：

第三步

在需要应用编辑器的Model属性中设置 DataAnnotations，比如：

第四步

在视图中使用 @Html.EditorFor(model => model.Content) 即可加载编辑器。
