Answer 1

需自己写个DataGridViewColumn
参考代码:
 public class CalendarColumn : DataGridViewColumn
    {
        public CalendarColumn()
            : base(new CalendarCell())
        {
        }
        public override DataGridViewCell CellTemplate
        {
            get
            {
                return base.CellTemplate;
            }
            set
            {
                if (value != null && !value.GetType().IsAssignableFrom(typeof(CalendarCell)))
                {
                    throw new InvalidCastException("Must   be   a   CalendarCell ");
                }
                base.CellTemplate = value;
            }
        }
    }    public class CalendarCell : DataGridViewTextBoxCell
    {        public CalendarCell()
            : base()
        {            // this.Style.Format = "d ";
        }        public override void InitializeEditingControl(int rowIndex, object initialFormattedValue, DataGridViewCellStyle dataGridViewCellStyle)
        {            base.InitializeEditingControl(rowIndex, initialFormattedValue, dataGridViewCellStyle);
            CalendarEditingControl ctl = DataGridView.EditingControl as CalendarEditingControl;
            ctl.Value = Convert.ToDateTime(this.Value.ToString());
        }        public override Type EditType
        {
            get
            {
                return typeof(CalendarEditingControl);
            }
        }        public override Type ValueType
        {
            get
            {
                return typeof(DateTime);
            }
        }        public override object DefaultNewRowValue
        {
            get
            {
                DateTime a = Convert.ToDateTime("00:00:00");
                return a;
            }
        }
    }    class CalendarEditingControl : DateTimePicker, IDataGridViewEditingControl
    {        DataGridView dataGridView;
        private bool valueChanged = false;
        int rowIndex;        public CalendarEditingControl()
        {
//            this.Format = DateTimePickerFormat.Time;
            this.Format = DateTimePickerFormat.Custom;
            this.CustomFormat = "HH:mm";            
            this.ShowUpDown = true;
        }
        public object EditingControlFormattedValue
        {
            get
            {
               
                return this.Value.ToLongTimeString();
            }
            set
            {
                String newValue = value as String;                if (newValue != null)
                {                    this.Value = Convert.ToDateTime(newValue);
                }
            }
        }
        public object GetEditingControlFormattedValue(DataGridViewDataErrorContexts context)
        {
            return EditingControlFormattedValue;
        }        public void ApplyCellStyleToEditingControl(DataGridViewCellStyle dataGridViewCellStyle)
        {
            this.Font = dataGridViewCellStyle.Font;
            this.CalendarForeColor = dataGridViewCellStyle.ForeColor;
            this.CalendarMonthBackground = dataGridViewCellStyle.BackColor;
        }
        public int EditingControlRowIndex
        {
            get
            {
                return rowIndex;
            }
            set
            {
                rowIndex = value;
            }
        }
        public bool EditingControlWantsInputKey(Keys key, bool dataGridViewWantsInputKey)
        {            switch (key & Keys.KeyCode)
            {
                case Keys.Left:
                case Keys.Up:
                case Keys.Down:
                case Keys.Right:
                case Keys.Home:
                case Keys.End:
                case Keys.PageDown:
                case Keys.PageUp:
                    return true;
                default:
                    return false;
            }
        }
        public void PrepareEditingControlForEdit(bool selectAll)
        {        }
        public bool RepositionEditingControlOnValueChange
        {
            get
            {
                return false;
            }
        }
        public DataGridView EditingControlDataGridView
        {
            get
            {
                return dataGridView;
            }
            set
            {
                dataGridView = value;
            }
        }
        public bool EditingControlValueChanged
        {
            get
            {
                return valueChanged;
            }
            set
            {
                valueChanged = value;
            }
        }
        public Cursor EditingPanelCursor
        {
            get
            {
                return base.Cursor;
            }
        }        protected override void OnValueChanged(EventArgs eventargs)
        {            valueChanged = true;            this.EditingControlDataGridView.NotifyCurrentCellDirty(true);
            base.OnValueChanged(eventargs);
        }
    }

Answer 2

自己写个控件，前面是textbox后面是按钮 出发时间控件 选完后textbox显示 选定时间
然后在绘制单元格事件的时候将控件覆盖到该列再就是重写一个datagridview的列

這個裡面就有你想要的，我個人覺得還不錯！你試試看！

Answer 4

对列的数据类型做判断：
if(dataGridView1.Columns[i].ValueType == typeof(DateTime))
{
   //该列所有单元格配置成时间控件
}
