  • ExtNet第二篇

    接下来演示第一个EXTNET使用案例,在演示之前请容我首先先介绍EXTNET中最基本的几个标记元素:

         ext:ResourceManager : 很明示是代码标记是管理EXTNET中的所有代码,如果没有此标记,EXTNET代码将不会运行。

           ext:Store :  存储作用     

         ext:GridPanel: 显示表格。

         注意:EXTNET操作方式是基于数据,所以将页面显示的数据可以优先存储在ext:Store标记中,然后能过GridPanel绑定数据存储即可,类似之前WebForm中绑定数据源的方式,只不将数据直接绑定在ext:Store标签中,然后通过ext:GridPanel来显示或者读取ext:Store中的数据即可,文章后将会继续说明方式,目前只是简单说明使用。同时ext:Store中可以绑定JSON,也可以绑定数组数据,还可以XML,大家可以多尝试,同时也告诉一个好消息,EXTNET的所有控件都是可以托动实现,与WebForm开发方式一样,漂亮的页面,只需几分钟就搞定,特别符合没地tml+css的程序员们。

     

    第一、页面代码如下:

    View Code
     1 <%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default" %>
     2 
     3 <%@ Register assembly="Ext.Net" namespace="Ext.Net" tagprefix="ext" %>
     4 
     5 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
     6 
     7 <html xmlns="http://www.w3.org/1999/xhtml" >
     8 <head runat="server">
     9     <title>Ext测试信息</title>
    10 </head>
    11 <body>
    12     <form id="form1" runat="server">
    13      <ext:ResourceManager ID="ResourceManager1" runat="server" />
    14          <ext:Store ID="Store1" runat="server">
    15             <Reader>
    16                 <ext:JsonReader>
    17                     <Fields>
    18                         <ext:RecordField Name="EmployeeID" Type="Int"></ext:RecordField>
    19                         <ext:RecordField Name="LastName" Type="String"></ext:RecordField>
    20                         <ext:RecordField Name="City" Type="String"></ext:RecordField>
    21                         <ext:RecordField Name="HomePhone" Type="String"></ext:RecordField>
    22                         <ext:RecordField Name="Country" Type="String"></ext:RecordField>
    23                     </Fields>
    24                 </ext:JsonReader>
    25             </Reader>
    26          </ext:Store>
    27          <ext:GridPanel StoreID="Store1" ID="GridPanel1" runat="server" Height="300" Title="Title">
    28              <ColumnModel ID="ctl20">
    29                 <Columns>
    30                     <ext:Column Header="EmployeeID" DataIndex="EmployeeID"></ext:Column>
    31                     <ext:Column Header="LastName" DataIndex="LastName"></ext:Column>
    32                     <ext:Column Header="City" DataIndex="City"></ext:Column>
    33                     <ext:Column Header="HomePhone" DataIndex="HomePhone"></ext:Column>
    34                     <ext:Column Header="Country" DataIndex="Country"></ext:Column>
    35                 </Columns>
    36              </ColumnModel>
    37          </ext:GridPanel>
    38     </form>
    39 </body>
    40 </html>

    第二、页面CS代码如下:

    View Code
     1 using System;
     2 using System.Collections.Generic;
     3 using System.Linq;
     4 using System.Web;
     5 using System.Web.UI;
     6 using System.Web.UI.WebControls;
     7 using Drgon.DAL;
     8 
     9 namespace Dragon.Web
    10 {
    11     public partial class _Default : System.Web.UI.Page
    12     {
    13         protected void Page_Load(object sender, EventArgs e)
    14         {
    15             this.Store1.DataSource = Employee.FindAll();
    16             this.Store1.DataBind();
    17         }
    18     }
    19 }

    第三、员工类如下:

    View Code
      1 // 
      2 // Generated by ActiveRecord Generator
      3 // 
      4 //
      5 namespace Drgon.DAL
      6 {
      7     using Castle.ActiveRecord;
      8     
      9     
     10     [ActiveRecord("Employees")]
     11     public class Employee : ActiveRecordBase
     12     {
     13         
     14         private int _employeeID;
     15         
     16         private string _lastName;
     17         
     18         private string _city;
     19         
     20         private string _address;
     21         
     22         private string _homePhone;
     23         
     24         private string _country;
     25         
     26         [PrimaryKey(PrimaryKeyType.Native)]
     27         public int EmployeeID
     28         {
     29             get
     30             {
     31                 return this._employeeID;
     32             }
     33             set
     34             {
     35                 this._employeeID = value;
     36             }
     37         }
     38         
     39         [Property()]
     40         public string LastName
     41         {
     42             get
     43             {
     44                 return this._lastName;
     45             }
     46             set
     47             {
     48                 this._lastName = value;
     49             }
     50         }
     51         
     52         [Property()]
     53         public string City
     54         {
     55             get
     56             {
     57                 return this._city;
     58             }
     59             set
     60             {
     61                 this._city = value;
     62             }
     63         }
     64         
     65         [Property()]
     66         public string Address
     67         {
     68             get
     69             {
     70                 return this._address;
     71             }
     72             set
     73             {
     74                 this._address = value;
     75             }
     76         }
     77         
     78         [Property()]
     79         public string HomePhone
     80         {
     81             get
     82             {
     83                 return this._homePhone;
     84             }
     85             set
     86             {
     87                 this._homePhone = value;
     88             }
     89         }
     90         
     91         [Property()]
     92         public string Country
     93         {
     94             get
     95             {
     96                 return this._country;
     97             }
     98             set
     99             {
    100                 this._country = value;
    101             }
    102         }
    103         
    104         public static void DeleteAll()
    105         {
    106             ActiveRecordBase.DeleteAll(typeof(Employee));
    107         }
    108         
    109         public static Employee[] FindAll()
    110         {
    111             return ((Employee[])(ActiveRecordBase.FindAll(typeof(Employee))));
    112         }
    113         
    114         public static Employee Find(int EmployeeID)
    115         {
    116             return ((Employee)(ActiveRecordBase.FindByPrimaryKey(typeof(Employee), EmployeeID)));
    117         }
    118     }
    119 }

    第四、效果如下:
