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.vista            DisplayMode = 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 = = Deve Xpress.

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, cel                 L.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); }     } }

Then drag a dateedit on the form xxx and enter XXX. Designer.cs the designer code This.dateedit =new DevExpress.XtraEditors.DateEdit ();
