BindingNavigator控件[通俗易懂]

WinForm之中BindingNavigator控件的使用 在微軟WinForm中,BindingNavigator控件主要用來綁定數據?？梢詫⒁粋€數據集合與該控件綁定,以進行數據

聯動的顯示效果。如圖下圖所示:

那么,下面我們就來用BindingNavigator控件做一下上圖所示的效果。 分析: 該案例以BindingNavigator控件為主線,我們定義一個實體類,將實體類以集合的形式顯示在DataGridView中,

同時,將BindingNavigator與DataGridView綁定,將BindingNavigator與文本框顯示數據綁定,將

BindingNavigator與Button控件綁定,來演示一個數據聯動的效果,已達到學習BindingNavigator控件的目的。

步驟: 首先,在Visual Studio中創建一個WinForm應用程序,在Form1中添加BindingNavigator控件,DataGridView控

件,兩個文本框,四個按鈕(分別表示:First,Previuos,Next,Last);

其次,在項目中添加一個用戶類User.cs,該類中有兩個屬性Name和Age; 示例代碼:

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,創建BindingSource對象,并在窗體加載事件中將BindingNavigator控件,與DataGridView,文本框,按

鈕控件進行數據綁定,進行數據聯動顯示效果; 示例代碼: 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    {        //創建一個泛型集合        List<User> users = new List<User>();        //        BindingSource bs = new BindingSource();        public MainForm()        {            InitializeComponent();        }        /// <summary>        /// 窗體加載事件        /// </summary>        /// <param name="sender"></param>        /// <param name="e"></param>        private void MainForm_Load(object sender, EventArgs e)        {            //創建用戶            User zh = new User("張三", 12);            User li = new User("李四",18);            User ww = new User("王五",20);            User ll = new User("劉六",30);            User X = new User("x-man",30);            User spaider = new User("spaiderman",25);            User ironman = new User("ironman",30);            //將用戶添加到List<>泛型集合的對象中            users.Add(zh);            users.Add(li);            users.Add(ww);            users.Add(ll);            users.Add(X);            users.Add(spaider);            users.Add(ironman);            //將泛型集合對象中的值賦給Bindingsource對象的DataSource            bs.DataSource = users;            //將數據顯示到DataGridView中去            this.dgvMain.DataSource = bs;            //綁定導航            this.bindingnavigator1.BindingSource = bs;            //與文本框進行數據綁定            this.txtName.DataBindings.Add("Text",bs,"Name");            this.txtAge.DataBindings.Add("Text",bs,"Age");        }        //移動到第一行        private void btnFirst_Click(object sender, EventArgs e)        {            this.bs.MoveFirst();        }        //移動到前一行        private void btnPrevious_Click(object sender, EventArgs e)        {             this.bs.MovePrevious();        }        //移動到下一行        private void btnNext_Click(object sender, EventArgs e)        {            this.bs.MoveNext();        }        //移動到最后一行        private void btnLast_Click(object sender, EventArgs e)        {            this.bs.MoveLast();        }    }}
