winform之自定义控件

这样的一个控件 肯定得通过自定义控件来实现了

 public class ProcessLabel : Control
    {

        public ProcessLabel()
        {

            //InitializeComponent();
            this.SetStyle(ControlStyles.AllPaintingInWmPaint | ControlStyles.OptimizedDoubleBuffer | ControlStyles.ResizeRedraw | ControlStyles.UserPaint, true);

        }

        private int distance = 16;

        public int Distance
        {
            get { return distance; }
            set
            {
                distance = value;
                Invalidate();
            }
        }

        private ImageList imagelist = new ImageList();

        public ImageList ImageList
        {
            get { return imagelist; }
            set
            {
                imagelist = value;
                Invalidate();
            }
        }

        private List<KeyValuePair<string, string>> links = new List<KeyValuePair<string, string>>();

        public List<KeyValuePair<string, string>> Links

使用

 ImageList myImageList = new ImageList();
            string filePath1 = Application.StartupPath + "\\Images\\orangelink.png";
            string filePath2 = Application.StartupPath + "\\Images\\blacklink.png";
            myImageList.Images.Add(Image.FromFile(filePath1));
            myImageList.Images.Add(Image.FromFile(filePath2));
            processLabel1.ImageList = myImageList;

            List<KeyValuePair<string, string>> source = new List<KeyValuePair<string, string>>();
            source.Add(new KeyValuePair<string,string>("下单","08:20"));
            source.Add(new KeyValuePair<string,string>("接单","14:20"));
            source.Add(new KeyValuePair<string,string>("配送","14:20"));
            source.Add(new KeyValuePair<string, string>("收货", "15:20"));
            source.Add(new KeyValuePair<string, string>("退货", "17:20"));
            source.Add(new KeyValuePair<string, string>("退款", "19:20"));
            source.Add(new KeyValuePair<string, string>("完毕", "21:20"));

            processLabel1.Links = source;
