我有一个 devexpressgridcontrol。我想在网格的一列中使用：repositoryLookUpEdit。我用数据库问题填充 repositoryLookUpEdit。此问题返回三列：IdPerson、Name 和 IdCity。列：IdPerson 和 Name 有数据，但 IdCity 我必须在应用程序中设置。
所以 - 在 gridcontrol 中，Idcity 列具有 fildename：IdCity 和 columnEdit：repositoryLookUpEdit。- repositoryLookUpEdit 具有 DisplayValue：CityName 和 ValueMember：IdCity。
我的问题是：
当我在城市的一行值的网格中选择并转到另一行时，第一行的值会消失。
我究竟做错了什么？你能给我一些建议吗？
我使用 Devexpress 9.2。
this.gvPerson = new DevExpress.XtraGrid.Views.Grid.GridView();
this.replueCity = new DevExpress.XtraEditors.Repository.RepositoryItemLookUpEdit();
this.replueCity.Columns.AddRange(new DevExpress.XtraEditors.Controls.LookUpColumnInfo[] { new DevExpress.XtraEditors.Controls.LookUpColumnInfo("IdCity", "IdCity", 20, DevExpress.Utils.FormatType.None, "", false, DevExpress.Utils.HorzAlignment.Default), new DevExpress.XtraEditors.Controls.LookUpColumnInfo("CityName", "CityName")});
this.replueCity.DisplayMember = "CityName";
this.replueCity.Name = "replueCity";
this.replueCity.NullText = "[Choose city]";
this.replueCity.TextEditStyle = DevExpress.XtraEditors.Controls.TextEditStyles.Standard;
this.replueOceny.ValueMember = "IdCity";
// CityColumn this.CityColumn.AppearanceCell.Options.UseTextOptions = true;
this.CityColumn.AppearanceCell.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;
this.CityColumn.AppearanceCell.TextOptions.VAlignment = DevExpress.Utils.VertAlignment.Center;
this.CityColumn.Caption = "Ocena";
this.CityColumn.ColumnEdit = this.replueCity;
this.CityColumn.FieldName = "IdCity";
this.CityColumn.Name = "IdCityName";
this.CityColumn.Visible = true;
