扩展控件属性

1、创建用户控件项目

2、    注释以下这一行 

        private void InitializeComponent()
        {
            components = new System.ComponentModel.Container();
            //this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
        }

    public partial class ExLabel : Label

    {

        public ExLabel()

        {

            InitializeComponent();

            this.Click += new EventHandler(exLabel_Click); 

        }

           protected override void OnMouseEnter(System.EventArgs e)  

           {  

               base.OnMouseEnter(e);

               this.ForeColor = Color.Black;

               this.BackColor = Color.White;

            //this.Font = new Font("宋体", 10F, FontStyle.Underline);  

           }  

         protected override void OnMouseLeave(System.EventArgs e)  

          {  

              base.OnMouseLeave(e);

              this.ForeColor = Color.White;

              this.BackColor = Color.Black;

              //this.Font = new Font("宋体", 10F, FontStyle.Regular);  

          }

         private void exLabel_Click(object sender, EventArgs e)

         {

             this.ForeColor = Color.Magenta;

             //this.BackColor = Color.Blue;

         }
