如何在一个DataGridView中的一列添加DateTimePicker控件

Question

如何在一个DataGridView中的一列上添加DateTimePicker控件,

Answer 1

这个要自定义了，可能用到如下的几个类：
从DataGridViewColumn继承一个新的列类型
从DataGridViewCell继承一个新的单元类型.
从DateTimePicker, IDataGridViewEditingControl继承新的DateTimePicker控件，

Answer 2

MSDN上其实有了这样的例子了，楼主找下看看.

Answer 3

MSDN：
您可以通过继承 DataGridViewColumn 类或该类的任何一个派生类来创建自己的列类，从而提供自定义的外观、行为或寄宿控件。有关更多信息，请参见如何：通过扩展 Windows 窗体 DataGridView 控件中单元格和列的行为和外观对其进行自定义

你建个组件类,下面是源码,自已再贴上去 public class CalendarColumn : DataGridViewColumn
    {        private bool showUpDown = true;        public bool ShowUpDown
        {
            get
            {
                return showUpDown;
            }
            set
            {
                showUpDown = value;
            }
        }        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;
            }
        }        private void InitializeComponent()
        {        }
    }

Answer 5

public class CalendarCell : DataGridViewTextBoxCell
    {
        public CalendarCell()
            : base()
        {
          
        }        public override void InitializeEditingControl(int rowIndex, object
            initialFormattedValue, DataGridViewCellStyle dataGridViewCellStyle)
        {
                      base.InitializeEditingControl(rowIndex, initialFormattedValue,dataGridViewCellStyle);
            CalendarEditingControl ctl =
            DataGridView.EditingControl as CalendarEditingControl;
            ctl.Text = this.Value.ToString();
            
        }        public override Type EditType
        {
            get
            {
               
                return typeof(CalendarEditingControl);
            }
        }        public override Type ValueType
        {
            get
            {
             
                return typeof(DateTime);
            }
        }        public override object DefaultNewRowValue
        {
            get
            {
                
                return DateTime.Now;
            }
        }
    }

Answer 7

DateTimePicker貌似没办法调整高度的，所以也就不能覆盖整个单元格
