DevExpress 常用控件使用整理


一、LookUpEdit 单选下拉框

/// <summary> /// 定义一个数据源 /// </summary> public static List<dynamic> IsYes {     get     {         return new List<dynamic>() {                 new { Status = 0, Name = "" },                 new { Status = 1, Name = "" }             };     } } /// <summary> /// 窗体打开时执行 /// </summary> private void InitFormControls() {     lookUpEdit1.Properties.Columns.Clear();     lookUpEdit1.Properties.DataSource = IsYes;//绑定数据源     lookUpEdit1.Properties.DisplayMember = "Name";    //=>要显示的字段名      lookUpEdit1.Properties.ValueMember = "Status";//=>获取或设置值的字段名      lookUpEdit1.Properties.Columns.AddRange(new DevExpress.XtraEditors.Controls.LookUpColumnInfo[] { new LookUpColumnInfo { Caption = "显示值", FieldName = "Name" } });//增加列     lookUpEdit1.Properties.BestFitMode = XtraEditors.Controls.BestFitMode.BestFit;//列宽自适应      lookUpEdit1.Properties.NullText = "请选择"; //value为null是显示"请选择" }

二、CheckedComboBoxEdit 多选下拉框

        /// <summary>         /// 定义一个数据源         /// </summary>         public static List<dynamic> IsYes         {             get             {                 return new List<dynamic>() {                     new { Status = 0, Name = "" },                     new { Status = 1, Name = "" }                 };             }         }         /// <summary>         /// 窗体打开时执行         /// </summary>         private void InitFormControls()         {             checkedComboBoxEdit1.Properties.DataSource = IsYes;//绑定数据源             checkedComboBoxEdit1.Properties.DisplayMember = "Name";    //=>要显示的字段名              checkedComboBoxEdit1.Properties.ValueMember = "Status";//=>获取或设置值的字段名              checkedComboBoxEdit1.Properties.NullText = "请选择"; //value为null是显示"请选择"         }

 PS:CheckedComboBoxEdit 的值多个值由逗号分隔如:“value1,value2……”

取值:var value= CheckedComboBoxEdit.EditVlue;

赋值:CheckedComboBoxEdit.SetEditValue(value1,value2……)

三、DateEdit 时间控件

//设置时间控件格选年份 dateEdit1.Properties.ShowToday = false; dateEdit1.Properties.ShowMonthHeaders = false; dateEdit1.Properties.CalendarView = DevExpress.XtraEditors.Repository.CalendarView.Vista; dateEdit1.Properties.VistaCalendarInitialViewStyle = DevExpress.XtraEditors.VistaCalendarInitialViewStyle.YearsGroupView; dateEdit1.Properties.VistaCalendarViewStyle = DevExpress.XtraEditors.VistaCalendarViewStyle.YearsGroupView; dateEdit1.Properties.Mask.EditMask = "yyyy"; dateEdit1.Properties.Mask.UseMaskAsDisplayFormat = true;  //设置时间控件格选月份 dateEdit1.Properties.ShowToday = false; dateEdit1.Properties.ShowMonthHeaders = true; dateEdit1.Properties.CalendarView = DevExpress.XtraEditors.Repository.CalendarView.Vista; dateEdit1.Properties.VistaCalendarInitialViewStyle = DevExpress.XtraEditors.VistaCalendarInitialViewStyle.YearView; dateEdit1.Properties.VistaCalendarViewStyle = DevExpress.XtraEditors.VistaCalendarViewStyle.YearView; dateEdit1.Properties.Mask.EditMask = "yyyy-MM"; dateEdit1.Properties.Mask.UseMaskAsDisplayFormat = true;  //设置时间控件格选季度 dateEdit1.Properties.ShowToday = false; dateEdit1.Properties.ShowMonthHeaders = false; dateEdit1.Properties.CalendarView = DevExpress.XtraEditors.Repository.CalendarView.Vista; dateEdit1.Properties.VistaCalendarInitialViewStyle = DevExpress.XtraEditors.VistaCalendarInitialViewStyle.QuarterView; dateEdit1.Properties.VistaCalendarViewStyle = DevExpress.XtraEditors.VistaCalendarViewStyle.QuarterView; dateEdit1.Properties.Mask.EditMask = "yyyy-MM"; dateEdit1.Properties.Mask.UseMaskAsDisplayFormat = true;  //设置开始时间和结束时间可选到时分秒 dateEdit1.Properties.VistaDisplayMode = DevExpress.Utils.DefaultBoolean.True; dateEdit1.Properties.VistaEditTime = DevExpress.Utils.DefaultBoolean.True; dateEdit1.Properties.EditFormat.FormatString = "yyyy-MM-dd HH:mm:ss"; dateEdit1.Properties.DisplayFormat.FormatString = "yyyy-MM-dd HH:mm:ss"; dateEdit1.Properties.Mask.MaskType = DevExpress.XtraEditors.Mask.MaskType.DateTime; dateEdit1.Properties.Mask.EditMask = "yyyy-MM-dd HH:mm:ss";  //设置日期显示格式: 设置三个属性(显示时、编辑时) dateEdit1.Properties.DisplayFormat.FormatString = "yyyy/MM/dd"; dateEdit1.Properties.EditFormat.FormatString = "yyyy/MM/dd"; dateEdit1.Properties.Mask.EditMask = "yyyy/MM/dd"; //不允许清空:    dateEdit1.Properties.AllowNullInput = DevExpress.Utils.DefaultBoolean.False;

四、TreeList 树结构列表

/// <summary> /// 数据源结构 /// </summary> public class TreeDto {     /// <summary>     /// Id     /// </summary>     public int Id { get; set; }     /// <summary>     /// 父类ID     /// </summary>     public int? PId { get; set; }     /// <summary>     /// 名称     /// </summary>     public string Name { get; set; } }

//初始化数据源 List<TreeDto> list = new List<TreeDto>() {     new TreeDto () {Id=1,Name="父节点一"},new TreeDto {Id=2,Name="父节点二"},     new TreeDto () {Id=3,Name="子节点一",PId=1},new TreeDto {Id=4,Name="子节点二",PId=1},     new TreeDto () {Id=5,Name="子节点三",PId=2},new TreeDto {Id=6,Name="子节点四",PId=2} }; //清空列 treeList1.Columns.Clear(); //新增一列 treeList1.Columns.Add(new TreeListColumn() { Caption= "名称", FieldName= "Name",Name= "treeListColumn1", Visible = true }); treeList1.OptionsBehavior.ReadOnly = true;//设置只读 treeList1.KeyFieldName = "Id";//设置主键  treeList1.ParentFieldName = "PId";//设置父级主键  treeList1.RootValue = null;//顶级树结点的值   treeList1.DataSource = list;//绑定数据源
