(二)c#Winform自定义控件-按钮

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;
        /// <summary>
        /// 按钮字体颜色
        /// </summary>
        [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)));
        /// <summary>
        /// 按钮字体
        /// </summary>
        [Description("按钮字体"), Category("自定义")]
        public Font BtnFont
        {
            get { return _btnFont; }
            set
            {
                _btnFont = value;
                this.lbl.Font = value;
            }
        }

        /// <summary>
        /// 按钮点击事件
        /// </summary>
        [Description("按钮点击事件"), Category("自定义")]
        public event EventHandler BtnClick;

        private string _btnText;
        /// <summary>
        /// 按钮文字
        /// </summary>
        [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
