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“：
<ext:ScriptManager runat="server" 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：
<ext:JsonReader ReaderID="CustomerID" Root="data" TotalProperty="totalCount">
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;}}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 {Load,Save }public class SaveStoreResponse {private bool success = true;private string errorMessage;public bool Success{get { return this.success; }set { this.success = value; }}public string ErrorMessage{get { return this.errorMessage; }set { this.errorMessage = value; }}public ConfirmationList ConfirmationList { get; set; } }}AjaxStoreResult 在 CustomerController 中的使用：
using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.Mvc;using System.Web.Mvc.Ajax;using CooliteMVC.Models;using CooliteMVC.Helper;using Coolite.Ext.Web;namespace CooliteMVC.Controllers{ public class CustomerController : Controller {ActionResult Index(){ViewData["Title"] = "Customer List";ViewData["Message"] = "Welcome to Coolite MVC! My name is Bruce.";return View();}public ActionResult List(int limit, int start, string dir, string sort){Random rand = new Random();IList<Customer> list = new List<Customer>();for (int i = start; i < start + limit; i++)list.Add(new Customer{CustomerID = "Customer" + i,Address = "Address" + i,City = "City" + rand.Next(1000),CompanyName = "Com" + rand.Next(1000),ContactName = "Contract" + rand.Next(1000),ContactTitle = "Title" + rand.Next(1000),Country = "Country" + rand.Next(1000),Email = rand.Next(1000) + "@live.com",Fax = rand.Next(1000).ToString() + rand.Next(1000),Mobile = rand.Next(1000).ToString() + rand.Next(1000),Notes = "Notes" + rand.Next(1000),Phone = "Phone" + rand.Next(1000),Region = "Region" + rand.Next(1000),TranDate = DateTime.Now.AddDays(rand.Next(30))});return new AjaxStoreResult(list, 100);}public ActionResult Save(){AjaxStoreResult ajaxStoreResult = new AjaxStoreResult(StoreResponseFormat.Save);try{StoreDataHandler dataHandler = new StoreDataHandler(Request["data"]);ChangeRecords<Customer> data = dataHandler.ObjectData<Customer>();foreach (Customer customer in data.Deleted){//db.Customers.Attach(customer);//db.Customers.DeleteOnSubmit(customer);}foreach (Customer customer in data.Updated){//db.Customers.Attach(customer);//db.Refresh(RefreshMode.KeepCurrentValues, customer);}foreach (Customer customer in data.Created){//db.Customers.InsertOnSubmit(customer);}}catch (Exception e){ajaxStoreResult.SaveResponse.Success = false;ajaxStoreResult.SaveResponse.ErrorMessage = e.Message;}return ajaxStoreResult;}}}页面的关键代码：
<ext:Store ID="dsCustomers" runat="server" ><Proxy><ext:HttpProxy Url="/Customer/List" Method ="GET" /></Proxy><UpdateProxy><ext:HttpWriteProxy Url="/Customer/Save" /></UpdateProxy><Reader><ext:JsonReader ReaderID="CustomerID" Root="data" TotalProperty="totalCount"><Fields><ext:RecordField Name="CustomerID" SortDir="ASC" /><ext:RecordField Name="CompanyName" /><ext:RecordField Name="ContactName" /><ext:RecordField Name="Email" /><ext:RecordField Name="Phone" /><ext:RecordField Name="Fax" /><ext:RecordField Name="Region" /><ext:RecordField Name="TranDate" Type="Date" /></Fields></ext:JsonReader></Reader><BaseParams><ext:Parameter Name="limit" Value="15" Mode="Raw" /><ext:Parameter Name="start" Value="0" Mode="Raw" /><ext:Parameter Name="dir" Value="ASC" /><ext:Parameter Name="sort" Value="CustomerID" /></BaseParams><SortInfo Field="CustomerID" Direction="ASC" /> </ext:Store>我们可以看到其实就是Url的写法不同而已： <ext:HttpProxy Url="/Customer/List" Method ="GET" /> <ext:HttpWriteProxy Url="/Customer/Save" /> 详细页面代码跟第一章差不多，这里不列出来。新闻热点
