如图中的自定义控件该如何实现呢？是comboBox还是ListView?
[解决办法]
经过我多年windows程序开发经验，介个应该是 comboBox
[解决办法]
重写ComboBox控件吧。

下面是一个日期控件的列子，根据需要改一下。

    public partial class ComboBoxEx : ComboBox 
    {
        private ToolStripDropDown DateTool = new ToolStripDropDown();
        private MonthCalendar M = new MonthCalendar();
        private ToolStripControlHost ToolHost;

        public ComboBoxEx()
        {
            this.DrawMode = DrawMode.OwnerDrawVariable;
            M.DateSelected += new DateRangeEventHandler(M_SelectDay);
            M.MaxSelectionCount = 1;
            M.ShowTodayCircle = false;
            InitTool();
        }

        public new int ItemHeight
        {
            get
            {
                return base.ItemHeight ;
            }
            set
            {
                base.ItemHeight = value;
                this.Size = new Size(this.Size.Width, this.ItemHeight + 6); 
 
            }
        }        

        protected override void WndProc(ref Message m)
        {
            base.WndProc(ref m);
            //if (m.Msg != 123)
            //{ 

            //}
            if (m.Msg == 0xf

 m.Msg == 0x133)
            {
                Graphics g = Graphics.FromHwnd(this.Handle);
                g.DrawRectangle(new Pen(Color.White  ,0), new Rectangle(this.ClientRectangle.Left, this.ClientRectangle.Top, this.ClientRectangle.Width - 1, this.ClientRectangle.Height - 1));
                g.Dispose();
            }
            if (m.Msg == 0x201)//在按下下拉按钮时
            {                                
                ShowDrop() ;
                this.Focus() ;
                return;
            }
            
        }

        private void InitTool()
        {                        
            ToolHost = new ToolStripControlHost(M); 
 
            ToolHost.AutoSize = false;
            ToolHost.Width = M.Width;
            ToolHost.Height = M.Height;
            DateTool.Items.Add(ToolHost);
        }

        private void ShowDrop()
        {
            try
            {
                M.TodayDate = DateTime.Parse(this.Text);
            }
            catch
            {
                M.TodayDate = DateTime.Now;
            }
            DateTool.Show(this, 0, this.Height);
        }

        private void M_SelectDay(object sender, DateRangeEventArgs e)
        {
            if (e.Start != null)
            {
                this.Text = e.Start.ToString("yyyy/MM/dd") ;
                M.Invalidate();                
                DateTool.Hide();
            }
        }
    }

这个应该是Combox控件的了,具体实现参考这里:http://www.cnblogs.com/feiyangqingyun/archive/2011/06/29/2093837.html 和这里http://www.cnblogs.com/Dennyzp/archive/2013/01/21/winformControl.html
