在流布局里面动态添加自定义控件，通过简单的按钮分页技术
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
看到这里，因为我基本没接触过cs的东西，一时间只有两三个思路，第一个思路是：自定义控件+panle控件（最终感觉行不通没有去做）
第二个思路是：自定义控件+DataGridView控件，尝试了几天，感觉方法有点繁琐，而且不一定能实现这种效果；
第三个思路是：自定义控件+流布局+自动生成。最终我通过第三种方法做出来了；
第四个思路是：wcf 只是有这个思路，还没有去实现，因为还没有了解过wcf。
首先：我先定义好我自己的自定义控件，代码和效果如下：
using System.Data;
using System.Data.SqlClient;
namespace menu
{
partial class MyControl
{
/// <summary>
/// 清理所有正在使用的资源。
/// </summary>
/// <param name="disposing">如果应释放托管资源，为 true；否则为 false。</param>
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
#region 组件设计器生成的代码
/// <summary>
/// 设计器支持所需的方法 - 不要
/// 使用代码编辑器修改此方法的内容。
/// </summary>
private void InitializeComponent()
{
this.components = new System.ComponentModel.Container();
System.ComponentModel.ComponentResourceManager resources = new System.ComponentModel.ComponentResourceManager(typeof(MyControl));
this.groupBox1 = new System.Windows.Forms.GroupBox();

((System.ComponentModel.ISupportInitialize)(this.pictureBox1)).BeginInit();
this.SuspendLayout();
//

this.label3.Location = new System.Drawing.Point(114, 70);
this.label3.Name = "label3";
this.label3.Size = new System.Drawing.Size(41, 12);
this.label3.TabIndex = 3;
this.label3.Text = "label3";
//
// label4

this.label4.AutoSize = true;
this.label4.Location = new System.Drawing.Point(116, 109);
this.label4.Name = "label4";
this.label4.Size = new System.Drawing.Size(41, 12);

this.label5.Location = new System.Drawing.Point(114, 148);
this.label5.Name = "label5";
this.label5.Size = new System.Drawing.Size(41, 12);
this.label5.TabIndex = 5;
this.label5.Text = "label5";
//

this.imageList1.ImageStream = ((System.Windows.Forms.ImageListStreamer)(resources.GetObject("imageList1.ImageStream")));
this.imageList1.TransparentColor = System.Drawing.Color.Transparent;
this.imageList1.Images.SetKeyName(0, "001.jpg");
this.imageList1.Images.SetKeyName(1, "002.jpg");
//
// MyControl
//
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 12F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.Controls.Add(this.label5);
this.Controls.Add(this.label4);

this.Controls.Add(this.label3);

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); } } } }
