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。using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using Coolite.Ext.Web;
namespace CooliteMVC.Helper
{
public class AjaxStoreResult : ActionResult
{
public AjaxStoreResult() { }
public AjaxStoreResult(object data)
{
this.Data = data;
}
public AjaxStoreResult(object data, int totalCount)
: this(data)
{
this.TotalCount = totalCount;
}
public AjaxStoreResult(StoreResponseFormat responseFormat)
{
this.ResponseFormat = responseFormat;
}
private object data;
public object Data
{
get { return this.data; }
set { this.data = value; }
}
private int totalCount;
public int TotalCount
{
get { return this.totalCount; }
set { this.totalCount = value; }
}
private StoreResponseFormat responseFormat = StoreResponseFormat.Load;
public StoreResponseFormat ResponseFormat
{
get { return this.responseFormat; }
set { this.responseFormat = value; }
}
private SaveStoreResponse saveResponse;
public SaveStoreResponse SaveResponse
{
get
{
if (this.saveResponse == null)
{
this.saveResponse = new SaveStoreResponse();
}
return this.saveResponse;
}
}
public override void ExecuteResult(ControllerContext context)
{
switch (this.ResponseFormat)
{
case StoreResponseFormat.Load:
string json = Coolite.Ext.Web.JSON.Serialize(Data);
json = "{data:" + json + ", totalCount:" + 100 + "}";
context.HttpContext.Response.Write(json);
break;
case StoreResponseFormat.Save:
Response response = new Response(true);
response.Success = this.SaveResponse.Success;
response.Msg = this.SaveResponse.ErrorMessage;
StoreResponseData saveResponse = new StoreResponseData();
saveResponse.Confirmation = this.SaveResponse.ConfirmationList;
response.Data = saveResponse.ToString();
response.Write();
break;
default:
throw new ArgumentOutOfRangeException();
}
}
}
public enum StoreResponseFormat

Save

public class SaveStoreResponse
{
private bool success = true;

public bool Success

页面的关键代码：
我们可以看到其实就是Url的写法不同而已： 详细页面代码跟第一章差不多，这里不列出来。
