ASP.NET―001:GridView绑定List、页面返回值具体实现

用惯了WPF的绑定，ASP.NET的绑定貌似不是很好用。下面看看ASP.NET绑定的用法。一般来说可以直接绑定DataTable的，不过我觉得绑定List比较符合面向对象编程。
绑定的方法是两句代码：
复制代码 代码如下:
GridView名.DataSource = List<自定义类>; 

GridView名.DataBind(); 

直接看例子吧，以下是一个绑定一个PersonModel类的例子。其中用到了页面返回参数，使用js传递，js可写在前端也可直接写在后台代码里。
项目结构：

效果：

实体类
复制代码 代码如下:
public class PersonModel
    {
        private int personIndex;

        public int PersonIndex
        {
            get { return personIndex; }

            set { personIndex = value; }
        }

        private string personID;

        public string PersonID
        {
            get { return personID; }

            set { personID = value; }
        }

        private string personName;

        public string PersonName
        {
            get { return personName; }

            set { personName = value; }
        }

        private string personSex;

        public string PersonSex
        {
            get { return personSex; }

            set { personSex = value; }
        }

        private int personAge;

        public int PersonAge
        {
            get { return personAge; }

            set { personAge = value; }
        }

        private bool personSelected = false;

        public bool PersonSelected
        {
            get { return personSelected; }

            set { personSelected = value; }
        }
    }

针对绑定的aspx页面写一个管理类，用于操作数据
复制代码 代码如下:
public class ChildFrmManager
    {
        private List personCollect = new List();

        private static ChildFrmManager instance = null;

        public List PersonCollect
        {
            get { return personCollect; }

            set { personCollect = value; }
        }

        public static ChildFrmManager DoGetInstance()
        {
            if (instance == null)
            {
                instance = new ChildFrmManager();
            }

            return instance;
        }

        public void DoAddPersons()
        {
            for (int i = 0; i < 20; i++)
            {
                PersonModel model = new PersonModel();

                model.PersonIndex = i + 1;

                model.PersonID = System.Guid.NewGuid().ToString();

                model.PersonName = "测试" + i;

                model.PersonAge = 27 + i;

                model.PersonSex = i % 2 == 0 ? "男" : "女";

                model.PersonSelected = false;

                this.PersonCollect.Add(model);
            }
        }
    }

绑定的页面前端
复制代码 代码如下:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="ChildFrm.aspx.cs" Inherits="ASPNetGridView.Pages.ChildFrm" %>

   

<
   

绑定页面后台
复制代码 代码如下:
 public partial class ChildFrm : System.Web.UI.Page
    {
        private ChildFrmManager dManager = null;

        protected PersonModel selectItem = null;

        protected void Page_Load(object sender, EventArgs e)
        {
            dManager = ChildFrmManager.DoGetInstance();

            if (!IsPostBack)
            {
                dManager.DoAddPersons();

                this.dgPersons.DataSource = dManager.PersonCollect;

                this.dgPersons.DataBind();
            }
        }

        protected void Selcted_Click(object sender, EventArgs e)
        {
            int selectIndex = this.dgPersons.SelectedIndex;

            foreach (PersonModel mitem in dManager.PersonCollect)
            {
                if (mitem.PersonIndex - 1 == selectIndex)
                {
                    mitem.PersonSelected = true;
                }
                else
                {
                    mitem.PersonSelected = false;
                }
            }

            selectItem = dManager.PersonCollect[selectIndex];

            string vbCrLf = " ";

            string strscript = "" + vbCrLf;

            if (!IsClientscriptBlockRegistered("clientscript"))
            {
                RegisterClientscriptBlock("clientscript", strscript);
            }
        }
    }

承载绑定页面的页面
复制代码 代码如下:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="frameFrm.aspx.cs" Inherits="ASPNetGridView.Pages.frameFrm" %>

主页面，获取返回值的js在前端
复制代码 代码如下:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="ASPNetGridView._Default" %>
