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 = "是" },
                new { Status = 1, Name = "否" }
            };
    }
}
/// <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"
}

效果：

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 = "是" },
                    new { Status = 1, Name = "否" }
                };
            }
        }
        /// <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"
        }

效果：

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

效果：

五、TreeListLookupEdit 下拉树

//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}
};
treeListLookUpEdit1.Properties.DataSource = list;
treeListLookUpEdit1.Properties.DisplayMember = "Name";//显示值
treeListLookUpEdit1.Properties.ValueMember = "Id";//value
treeListLookUpEdit1.Properties.TreeList.KeyFieldName = "Id";//主键
treeListLookUpEdit1.Properties.TreeList.ParentFieldName = "PId";//父级主键
treeListLookUpEdit1.Properties.AllowNullInput = DevExpress.Utils.DefaultBoolean.True;//value可以为空
treeListLookUpEdit1.Properties.TreeList.ExpandAll();//默认全部展开

//treeListLookUpEdit1中自带的一个TreeList控件
treeListLookUpEdit1TreeList.Columns.Clear();
DevExpress.XtraTreeList.Columns.TreeListColumn treeListColumn1 = new DevExpress.XtraTreeList.Columns.TreeListColumn();
treeListColumn1.Caption = "名称";
treeListColumn1.FieldName = "Name";
treeListColumn1.Name = "treeListColumn1";
treeListColumn1.Visible = true;
treeListColumn1.VisibleIndex = 1;
treeListLookUpEdit1TreeList.Columns.Add(treeListColumn1);

treeListLookUpEdit1TreeList.Location = new System.Drawing.Point(0, 0);
//treelist.Name = "ParentId.PropertiesTreeList";
treeListLookUpEdit1TreeList.OptionsBehavior.EnableFiltering = true;
treeListLookUpEdit1TreeList.OptionsBehavior.PopulateServiceColumns = true;
treeListLookUpEdit1TreeList.OptionsView.ShowIndentAsRowStyle = true;
treeListLookUpEdit1TreeList.Size = new System.Drawing.Size(200, 100);
treeListLookUpEdit1TreeList.TabIndex = 0;
treeListLookUpEdit1.Properties.NullText = "";

效果：

六、附加内容

EditText宽度自适应

layoutControlItem1.TextAlignMode = DevExpress.XtraLayout.TextAlignModeItem.AutoSize;
