准备工作

该控件将继承基类控件UCControlBase，如果你还对UCControlBase不了解的下，

请移步 （一）c#Winform自定义控件-基类控件  查看

首先我们了解下要做的是什么，我们需要做一个可以自定义填充颜色，有圆角边框，有角标的按钮

开始

添加一个用户控件，命名为UCBtnExt ，继承 UCControlBase

先来看看我们按钮需要支持的属性吧

 1 #region 字段属性
 2         [Description("是否显示角标"), Category("自定义")]
 3         public bool IsShowTips
 4         {
 5             get
 6             {
 7                 return this.lblTips.Visible;
 8             }
 9             set
10             {
11                 this.lblTips.Visible = value;
12             }
13         }
14 
15         [Description("角标文字"), Category("自定义")]
16         public string TipsText
17         {
18             get
19             {
20                 return this.lblTips.Text;
21             }
22             set
23             {
24                 this.lblTips.Text = value;
25             }
26         }
27 
28         private Color _btnBackColor = Color.White;
29         [Description("按钮背景色"), Category("自定义")]
30         public Color BtnBackColor
31         {
32             get { return _btnBackColor; }
33             set
34             {
35                 _btnBackColor = value;
36                 this.BackColor = value;
37             }
38         }
39 
40         private Color _btnForeColor = Color.Black;
41         /// 

42         /// 按钮字体颜色
43         /// 
44         [Description("按钮字体颜色"), Category("自定义")]
45         public Color BtnForeColor
46         {
47             get { return _btnForeColor; }
48             set
49             {
50                 _btnForeColor = value;
51                 this.lbl.ForeColor = value;
52             }
53         }
54 
55         private Font _btnFont = new System.Drawing.Font("微软雅黑", 12F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(134)));
56         /// 

57         /// 按钮字体
58         /// 
59         [Description("按钮字体"), Category("自定义")]
60         public Font BtnFont
61         {
62             get { return _btnFont; }
63             set
64             {
65                 _btnFont = value;
66                 this.lbl.Font = value;
67             }
68         }
69 
70         /// 

71         /// 按钮点击事件
72         /// 
73         [Description("按钮点击事件"), Category("自定义")]
74         public event EventHandler BtnClick;
75 
76         private string _btnText;
77         /// 

78         /// 按钮文字
79         /// 
80         [Description("按钮文字"), Category("自定义")]
81         public string BtnText
82         {
83             get { return _btnText; }
84             set
85             {
86                 _btnText = value;
87                 lbl.Text = value;
88             }
89         }
90         #endregion

有了属性是不是就更明了呢

还有最后关键的一点东西，就是按钮的点击事件

1         private void lbl_MouseDown(object sender, MouseEventArgs e)
2         {
3             if (this.BtnClick != null)
4                 BtnClick(this, e);
5         }

至此基本上就完工了，下面列出了完整的代码
