最新在做CRM的报表，查询条件只需要年月，DateEdit 以及几个时间控件都用的不顺，强迫症犯了一怒之下起了重写DateEdit的想法
新建一个类
CXDateEdit
using DevExpress.XtraEditors;
using DevExpress.XtraEditors.Calendar;
using DevExpress.XtraEditors.Controls;
using DevExpress.XtraEditors.Popup;
using DevExpress.XtraEditors.Repository;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace MLTY.Business.Report
{
public class CXDateEdit : DateEdit
{
public CXDateEdit()
{
Properties.VistaDisplayMode = DevExpress.Utils.DefaultBoolean.True;
Properties.DisplayFormat.FormatString = "yyyy-MM";
Properties.DisplayFormat.FormatType = DevExpress.Utils.FormatType.DateTime;
Properties.Mask.EditMask = "yyyy-MM";
Properties.ShowToday = false;
}
protected override PopupBaseForm CreatePopupForm()
{
if (Properties.VistaDisplayMode == DevExpress.Utils.DefaultBoolean.True)
return new CustomVistaPopupDateEditForm(this);
return new PopupDateEditForm(this);
}
private DateResultModeEnum _dateMode = DateResultModeEnum.FirstDayOfMonth;
public DateResultModeEnum DateMode
{
get { return _dateMode; }
set { _dateMode = value; }
}
public enum DateResultModeEnum : int
{
//虽然是年月控件，但日期Datetime肯定是2012-01-01这种格式
//所以，这个枚举定义了年月控件返回本月的第一天，还是本月的最后一天作为DateEditEx的值
FirstDayOfMonth = 1,
LastDayOfMonth = 2
}
}
public class CustomVistaPopupDateEditForm : VistaPopupDateEditForm
{
public CustomVistaPopupDateEditForm(DateEdit ownerEdit) : base(ownerEdit) { }
protected override DateEditCalendar CreateCalendar()
{
return new CustomVistaDateEditCalendar(OwnerEdit.Properties, OwnerEdit.EditValue);
}
}
public class CustomVistaDateEditCalendar : VistaDateEditCalendar
{
public CustomVistaDateEditCalendar(RepositoryItemDateEdit item, object editDate) : base(item, editDate) { }
protected override void Init()
{
base.Init();
this.View = DateEditCalendarViewType.YearInfo;
}
public CXDateEdit.DateResultModeEnum DateMode
{
get { return ((CXDateEdit)this.Properties.OwnerEdit).DateMode; }
}
protected override void OnItemClick(DevExpress.XtraEditors.Calendar.CalendarHitInfo hitInfo)
{
DayNumberCellInfo cell = hitInfo.HitObject as DayNumberCellInfo;
if (View == DateEditCalendarViewType.YearInfo)
{
DateTime dt = new DateTime(DateTime.Year, cell.Date.Month, 1, 0, 0, 0);
if (DateMode == CXDateEdit.DateResultModeEnum.FirstDayOfMonth)
{
OnDateTimeCommit(dt, false);
}
else
{
DateTime tempDate = dt.AddMonths(1).AddDays(-1);
tempDate = new DateTime(tempDate.Year, tempDate.Month, tempDate.Day, 23, 59, 59);
OnDateTimeCommit(tempDate, false);
}
}
else
base.OnItemClick(hitInfo);
}
}
}
然后在窗体xxx上拖一个dateedit ，进入xxx.Designer.cs 将设计器代码 this.dateedit =new DevExpress.XtraEditors.DateEdit();
改成 重写的类
