    }
}
使用的时候
CalendarColumn coldtCheckDate = new CalendarColumn();
coldtCheckDate.DataPropertyName = "dtCheckDate";
coldtCheckDate.HeaderText = "检查日期";
checkgird.Columns.Add(coldtCheckDate);

Answer 2

请把问题描述清楚.            MDataGridViewCalendarColumn mdc = new MDataGridViewCalendarColumn();
            DataGridView dgv = new DataGridView();
            dgv.Columns.Add(mdc);供你参考

Answer 4

谢谢楼上，不过我要的是winform中的C#.您的这段程序有问题出错提示如下
"找不到类型或命名空间名称“MDataGridViewCalendarColumn”(是否缺少 using 指令或程序集引用?)"
