winform控件之BindingNavigator

BindingNavigator控件可以為我們綁定的數據提供一個導航的功能,默認的工具是這個樣子的,我們可以根據需求再增加功能

1.BindingNavigator用法

1.1界面布局

界面布局如下

一個BindingNavigator名為bindingnavigator1

一個DataGridView名為DataGridView1

兩個TextBox分別為TextBox1和TextBox2

四個Button分別為First,Previous,Next,Last

1.2用法示例

BindingNavigator其實是需要BindingSource作為橋梁和真正的數據一起其他UI進行聯動顯示的,所以我們首先需要創建我們自己的BindingSource和具體的數據,這里我們創建一個User類,代碼如下

    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; }        }    }

然后我們需要創建一個BindingSource,并且填充數據,具體代碼如下

    public partial class FormMain : Form    {        List<User> users = new List<User>();        BindingSource bs = new BindingSource();        public FormMain(ArrayList arrip_list)        {            InitializeComponent();            //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.dataGridView1.DataSource = bs;            //綁定導航            this.bindingNavigator1.BindingSource = bs;            //與文本框進行數據綁定            this.textBox1.DataBindings.Add("Text", bs, "Name");            this.textBox2.DataBindings.Add("Text", bs, "Age");        }        private void First_Click(object sender, EventArgs e)        {            this.bs.MoveFirst();        }        private void Previuos_Click(object sender, EventArgs e)        {            this.bs.MovePrevious();        }        private void Last_Click(object sender, EventArgs e)        {            this.bs.MoveLast();        }        private void Next_Click(object sender, EventArgs e)        {            this.bs.MoveNext();        }            }

都做好之后我們就可以看到效果了,BindingNavigator就相當于提供了一個導航欄,可以在這個導航欄上直接進行簡單的查找,增加,刪除等動作
