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

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()
{

}
}
