DataSource
、DisplayMember
、ValueMember
、ImmediatePopup、AutoSearchColumnIndex、SearchMode获取值
string id = this.lookUpEdit1.EditValue.ToString(); //是lookUpEdit.Properties.ValueMember的值 string name = this.lookUpEdit1.Text.Trim(); //是lookUpEdit.Properties.DisplayMember的值
SearchMode:
OnlyInPopup:配合ImmediatePopup=true使用,并根据输入的字符从头部开始匹配AutoSearchColumnIndex属性指定栏位字段的值,默认为第一栏位0
AutoComplete,配合ImmediatePopup=true使用,并在输入框自动完成你想要输入的数据,同时下拉窗体自动匹配最佳记录,这个值匹配DisplayMember对应的字段。
特点:能在输入框显示匹配的数据,并且下拉窗体显示匹配的记录
AutoFiler : 配合ImmediatePopup=true使用,并在输入框自动完成你想要输入的数据,同时下拉窗体自动过滤不匹配的记录。这个值匹配DisplayMember对应的字段。
特点:能过滤掉不想要的数据,自动过滤掉不匹配的数据
// lookUpEdit1 lookUpEdit1.Properties.DisplayMember = "CLASS_NAME"; // 可以不指定,但是影响Text lookUpEdit1.Properties.ValueMember = "CLASS_CODE"; // 可以不指定,但是影响 EditValue lookUpEdit1.Properties.DataSource = dt; // 修改此项可以设置为是否允许用户编辑DisableTextEditor(不允许,默认), // Standard(允许编辑) ,但是必须是下拉框内数据,否则清空编辑器 lookUpEdit1.Properties.TextEditStyle = DevExpress.XtraEditors.Controls.TextEditStyles.Standard;
RepositoryItemLookUpEdit
下拉框
public class ComboxList { public string ItemCode { get; set; } public string ItemName { get; set; } public ComboxList(string itemCode, string itemName) { ItemCode = itemCode; ItemName = itemName; } } BindingList<ComboxList> blSummaryType = new BindingList<ComboxList>() { new ComboxList("0","Sum"), new ComboxList("1","Min"), new ComboxList("2","Max"), new ComboxList("3","Count"), new ComboxList("4","Average"), new ComboxList("5","Custom"), new ComboxList("6","None") }; RepositoryItemLookUpEdit riluSummaryType = new RepositoryItemLookUpEdit() { DataSource = blSummaryType, DisplayMember = "ItemName", ValueMember = "ItemCode", NullText = "" }; riluSummaryType.Columns.AddRange(new DevExpress.XtraEditors.Controls.LookUpColumnInfo[] { new DevExpress.XtraEditors.Controls.LookUpColumnInfo("ItemCode","代码",30), new DevExpress.XtraEditors.Controls.LookUpColumnInfo("ItemName","名称",70), }); gridView2.Columns["SummaryType"].ColumnEdit = riluSummaryType;

和RepositoryItemLookUpEdit不同之处在于他具有Grid的属性,可以多列,可以点击表头的小漏斗过滤数据
使用方法
RepositoryItemGridLookUpEdit riluFormatType = new RepositoryItemGridLookUpEdit() { DataSource = blFormatType, DisplayMember = "ItemName", ValueMember = "ItemCode", NullText = "" }; GridColumn riglupgcId = riluFormatType.View.Columns.AddField("ItemCode"); riglupgcId.Caption = "编号"; riglupgcId.VisibleIndex = 0; riglupgcId.Width = 30; GridColumn riglupgcName = riluFormatType.View.Columns.AddField("ItemName"); riglupgcName.Caption = "名称"; riglupgcName.VisibleIndex = 1; riglupgcName.Width = 70; riluFormatType.View.Columns.Add(riglupgcId); riluFormatType.View.Columns.Add(riglupgcName); gridView2.Columns["FormatType"].ColumnEdit = riluFormatType;
