WinForm之中BindingNavigator控件的使用

WinForm之中BindingNavigator控件的使用
在微软WinForm中,BindingNavigator控件主要用来绑定数据。可以将一个数据集合与该控件绑定,以进行数据

联动的显示效果。如图下图所示:

WinForm之中BindingNavigator控件的使用 - Bill  - 已经开始···

那么,下面我们就来用BindingNavigator控件做一下上图所示的效果。
分析:
该案例以BindingNavigator控件为主线,我们定义一个实体类,将实体类以集合的形式显示在DataGridView中,

同时,将BindingNavigator与DataGridView绑定,将BindingNavigator与文本框显示数据绑定,将

BindingNavigator与Button控件绑定,来演示一个数据联动的效果,已达到学习BindingNavigator控件的目的。

步骤:
首先,在Visual Studio中创建一个WinForm应用程序,在Form1中添加BindingNavigator控件,DataGridView控

件,两个文本框,四个按钮(分别表示:First,Previuos,Next,Last);

其次,在项目中添加一个用户类User.cs,该类中有两个属性Name和Age;
示例代码:
using System;
using System.Collections.Generic;
using System.Text;

namespace BindingDemo
{
    public class User
    {
        public User()
        {

        }
        public User(string name,int age)
        {
            this.Name = name;
            this.Age = age;
        }
        private string name;

        public string Name
        {
            get { return name; }
            set { name = value; }
        }
        private int age;

        public int Age
        {
            get { return age; }
            set { age = value; }
        }

    }
}

再次,在Form1的代码之中,创建User对象,并将对象保存到List<>泛型集合之中,并显示到DataGridView中;
关键代码:
        //创建一个泛型集合
        List<User> users = new List<User>();

        /// <summary>
        /// 窗体加载事件
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void MainForm_Load(object sender, EventArgs e)
        {
            //创建用户
            User zh = new User("张三", 12);
            User li = new User("李四",18);
            User ww = new User("王五",20);
            User ll = new User("刘六",30);
            User X = new User("x-man",30);
            User spaider = new User("spaiderman",25);
            User ironman = new User("ironman",30);
            //将用户添加到List<>泛型集合的对象中
            users.Add(zh);
            users.Add(li);
            users.Add(ww);
            users.Add(ll);
            users.Add(X);
            users.Add(spaider);
            users.Add(ironman);
 }
再次,创建BindingSource对象,并在窗体加载事件中将BindingNavigator控件,与DataGridView,文本框,按

钮控件进行数据绑定,进行数据联动显示效果;
示例代码: Form1.cs
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace BindingDemo
{
    public partial class MainForm : Form
    {
        //创建一个泛型集合
        List<User> users = new List<User>();
        //
        BindingSource bs = new BindingSource();

        public MainForm()
        {
            InitializeComponent();
        }


        /// <summary>
        /// 窗体加载事件
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void MainForm_Load(object sender, EventArgs e)
        {
            //创建用户
            User zh = new User("张三", 12);
            User li = new User("李四",18);
            User ww = new User("王五",20);
            User ll = new User("刘六",30);
            User X = new User("x-man",30);
            User spaider = new User("spaiderman",25);
            User ironman = new User("ironman",30);
            //将用户添加到List<>泛型集合的对象中
            users.Add(zh);
            users.Add(li);
            users.Add(ww);
            users.Add(ll);
            users.Add(X);
            users.Add(spaider);
            users.Add(ironman);

            //将泛型集合对象中的值赋给Bindingsource对象的DataSource
            bs.DataSource = users;
            //将数据显示到DataGridView中去
            this.dgvMain.DataSource = bs;
            //绑定导航
            this.bindingNavigator1.BindingSource = bs;
            //与文本框进行数据绑定
            this.txtName.DataBindings.Add("Text",bs,"Name");
            this.txtAge.DataBindings.Add("Text",bs,"Age");
        }

        //移动到第一行         private void btnFirst_Click(object sender, EventArgs e)
        {
            this.bs.MoveFirst();
        }

        //移动到前一行
        private void btnPrevious_Click(object sender, EventArgs e)
        {
             this.bs.MovePrevious();
        }

        //移动到下一行
        private void btnNext_Click(object sender, EventArgs e)
        {
            this.bs.MoveNext();
        }

        //移动到最后一行
        private void btnLast_Click(object sender, EventArgs e)
        {
            this.bs.MoveLast();
        }
    }
}
