Coolite Cool Study 3 MVC + Coolite 的实现代码

因为默认的 MVC 的样式文件里对于的 table 和 其他相关样式（h1～h6） 与Coolite有冲突，会导致GridPanel走样，大家记得先把那个table 和  h1～h6的样式清除掉才看到GridPanel的帅脸面 …

项目文件分布：

关于Coolite在MVC中的配置文件跟一般webform是一样的。 但在MVC的Global.asax中，需要在 RegisterRoutes 方法里加上这一句：

routes.IgnoreRoute("{exclude}/{coolite}/coolite.axd");

另外 scriptManager 要注明 IDMode="Static“：

其中唯一与一般MVC不同的是，我们需要定义自己的ActionResult来返回Json结果给客户端。因为Coolite 的JsonReader 要求的格式大致都是这样：{data: [{…}], totalCount: …}

关于JsonReader的一般用法：

所以， 要继承MVC ActionResult 的抽象方法 public override void ExecuteResult(ControllerContext context)  来返回给 JsonReader   合适口味的 JsonResult , 不然它就不认人了。

以下代码实现了对Json Response & Save Response 的简单封装。

我们可以看到其实就是Url的写法不同而已：
