WinForm中的用户控件实现分页功能

{ //定义的分页事件 public event EventHandler PageChanged; private int _PageIndex; public int PageIndex { get { return _PageIndex; } set { if (value < 1) { value = 1; } if (value>PageCount) { value = PageCount; } _PageIndex = value; this.textBox1.Text = _PageIndex.ToString(); //判断事件是否为空 if (PageChanged != null) { PageChanged(this, null); } } } public int PageCount { get; set; } public UserControl1() { InitializeComponent(); PageIndex = 1; PageCount = 10; this.textBox1.Text = PageIndex.ToString(); } private void button1_Click(object sender, EventArgs e) { PageIndex = 1; } private void button2_Click(object sender, EventArgs e) { PageIndex--; } private void button3_Click(object sender, EventArgs e) { PageIndex++; } private void button4_Click(object sender, EventArgs e) { PageIndex = PageCount; } }
