Answer 4

DateTimePicker dtp=new DateTimePicker(); 
dataGridView1.Controls.Add(dtp);
     Rectangle rect = this.dataGridView1.GetCellDisplayRectangle(this.dataGridView1.CurrentCell.ColumnIndex, this.dataGridView1.CurrentCell.RowIndex, false);
                            this.dtp.Left = rect.Left;
                            this.dtp.Top = rect.Top;
                            this.dtp.Width = rect.Width;
                            this.dtp.Height = rect.Height;

自定义一个时间控件使用的时候
       CalendarColumn datecol = new CalendarColumn();
            datecol.HeaderText = "日期";
            datecol.DataPropertyName = "sDate";//绑定的数据源
            this.dgvProduct.Columns.Add(datecol);
