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

#region 字段属性[Description("是否显示角标"), Category("自定义")]public bool IsShowTips{ get { return this.lblTips.Visible; } set { this.lblTips.Visible = value; }}[Description("角标文字"), Category("自定义")]public string TipsText{ get { return this.lblTips.Text; } set { this.lblTips.Text = value; }}private Color _btnBackColor = Color.White;[Description("按钮背景色"), Category("自定义")]public Color BtnBackColor{ get { return _btnBackColor; } set { _btnBackColor = value; this.BackColor = value; }}private Color _btnForeColor = Color.Black;/// /// 按钮字体颜色/// [Description("按钮字体颜色"), Category("自定义")]public Color BtnForeColor{ get { return _btnForeColor; } set { _btnForeColor = value; this.lbl.ForeColor = value; }}private Font _btnFont = new System.Drawing.Font("微软雅黑", 12F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(134)));/// /// 按钮字体/// [Description("按钮字体"), Category("自定义")]public Font BtnFont{ get { return _btnFont; } set { _btnFont = value; this.lbl.Font = value; }}/// /// 按钮点击事件/// [Description("按钮点击事件"), Category("自定义")]public event EventHandler BtnClick;private string _btnText;/// /// 按钮文字/// [Description("按钮文字"), Category("自定义")]public string BtnText{ get { return _btnText; } set { _btnText = value; lbl.Text = value; }}#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

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

至此基本上就完工了，下面列出了完整的代码

用处：按钮有什么用，我想我不用解释了吧

效果：

自定义按钮效果最后的话
