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“：

<ext:ScriptManager ID="ScriptManager1" 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;

}

}
 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

{

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

{

//

// GET: /Customer/
 public 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。
