前提
入行已经7,8年了，一直想做一套漂亮点的自定义控件，于是就有了本系列文章。

如果觉得写的还行，请点个 star 支持一下吧

准备工作
列表控件将被拆分为2部分，一个元素，一个列表，列表需要支持主副标题，图标等
开始
首先定义一个数据源类（其实更好的是应该接受object，然后通过绑定字段反射绑定数据，这样就不需要这个数据源类了，这里偷懒了）
1 /// <summary>
2 /// 列表实体
3 /// </summary>
4 [Serializable]
5 public class ListEntity
6 {
7 /// <summary>
8 /// 编码，唯一值
9 /// </summary>
10 public string ID { get; set; }
11 /// <summary>
12 /// 大标题
13 /// </summary>
14 public string Title { get; set; }
15 /// <summary>
16 /// 右侧更多按钮
17 /// </summary>
18 public bool ShowMoreBtn { get; set; }
19 /// <summary>
20 /// 右侧副标题
21 /// </summary>
22 public string Title2 { get; set; }
23 /// <summary>
24 /// 关联的数据源
25 /// </summary>
26 public object Source { get; set; }
27 }
我们创建元素控件，添加一个用户控件，命名UCListItemExt
需要提供一下属性
1 [Description("标题"), Category("自定义")]
2 public string Title
3 {
4 get { return label1.Text; }
5 set { label1.Text = value; }
6 }
7 [Description("副标题"), Category("自定义")]
8 public string Title2
9 {
10 get { return label3.Text; }
11 set
12 {
13 label3.Text = value;
14 label3.Visible = !string.IsNullOrEmpty(value);
15 }
16 }
17
18 [Description("标题字体"), Category("自定义")]
19 public Font TitleFont
20 {
21 get { return label1.Font; }
22 set
23 {
24 label1.Font = value;
25 }
26 }
27
28 [Description("副标题字体"), Category("自定义")]
29 public Font Title2Font
30 {
31 get { return label3.Font; }
32 set
33 {
34 label3.Font = value;
35 }
36 }
37
38 [Description("背景色"), Category("自定义")]
39 public Color ItemBackColor
40 {
41 get { return this.BackColor; }
42 set
43 {
44 this.BackColor = value;
45 }
46 }
47
48 [Description("标题文本色"), Category("自定义")]
49 public Color ItemForeColor
50 {
51 get { return label1.ForeColor; }
52 set { label1.ForeColor = value; }
53 }
54
55 [Description("副标题文本色"), Category("自定义")]
56 public Color ItemForeColor2
57 {
58 get { return label3.ForeColor; }
59 set { label3.ForeColor = value; }
60 }
61
62 [Description("是否显示右侧更多箭头"), Category("自定义")]
63 public bool ShowMoreBtn
64 {
65 get { return label2.Visible; }
66 set { label2.Visible = value; ; }
67 }
68
69 [Description("项选中事件"), Category("自定义")]
70 public event EventHandler ItemClick;
71
72 /// <summary>
73 /// 数据源
74 /// </summary>
75 public ListEntity DataSource { get; private set; }
开放一个对外的设置数据源入口
1 #region 设置数据

9 public void SetData(ListEntity data)
10 {
11 this.Title = data.Title;
12 this.Title2 = data.Title2;
13 this.ShowMoreBtn = data.ShowMoreBtn;
14 DataSource = data;
15 }
16 #endregion
再处理一下点击事件
1 private void item_MouseDown(object sender, MouseEventArgs e)
2 {
3 if (ItemClick != null)
4 {
5 ItemClick(this, e);
6 }
7 }
至此功能完成，看下完整代码

用处及效果
调用示例
1 List<ListEntity> lst = new List<ListEntity>();
2 for (int i = 0; i < 5; i++)
3 {
4 lst.Add(new ListEntity()
5 {
6 ID = i.ToString(),
7 Title = "选项" + i,
8 ShowMoreBtn = true,
9 Source = i
10 });
11 }
12 this.ucListExt1.SetList(lst);
