由于最近没什么事情，一直在看java基础，前几天接到上级的任务，得作出一个门禁系统的cs界面出来，能够实现分页，数据绑定需求如下图

}
自定义控件效果如下：
第二步：流布局+动态添加自定义控件
实现代码和效果如下：
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; namespace menu { public partial class Form3 : Form { public Form3() { InitializeComponent(); } private void Form3_Load(object sender, EventArgs e) { } private void button1_Click(object sender, EventArgs e) { this.flowLayoutPanel1.Controls.Clear(); n=n+1; int count = 15 * n; for(int i=1+15*(n-1);i<=count;i++) { MyControl mcl = new MyControl(); mcl.groupBox1.Text = i.ToString(); mcl.DataLoad(i); this.flowLayoutPanel1.Controls.Add(mcl); } } int n = 1; private void button3_Click(object sender, EventArgs e) { this.flowLayoutPanel1.Controls.Clear(); int count = 15 * n; for (int i = 1; i <= count; i++) { MyControl mcl = new MyControl(); mcl.groupBox1.Text = i.ToString(); mcl.DataLoad(i); this.flowLayoutPanel1.Controls.Add(mcl); } } private void button2_Click(object sender, EventArgs e) { this.flowLayoutPanel1.Controls.Clear(); if(n>=2) n = n - 1; int count = 15 * n; for (int i = 1 + 15 * (n - 1); i <= count; i++) { MyControl mcl = new MyControl(); mcl.groupBox1.Text = i.ToString(); mcl.DataLoad(i); this.flowLayoutPanel1.Controls.Add(mcl); } } } }
