I have a devexpressgridcontrol. I want to use in one column of the grid : repositoryLookUpEdit. I fill repositoryLookUpEdit with database question. This question return three columns : IdPerson , Name and IdCity. Colums : IdPerson and Name have data but IdCity I have to set in appication.
So - in gridcontrol the column Idcity has fildename : IdCity, and columnEdit : repositoryLookUpEdit. - repositoryLookUpEdit has DisplayValue : CityName, and ValueMember: IdCity.
And my question is:
When I choose in grid in one row value of city and I go to another row, the value from the first row disaper.
What am I doing wrong? Could you give me some advise?
I use 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;
You have to set ValueMember for replueCity (which is the editor in the column). You set it only for replueOceny.
Check string IdCity in all three cases: it must be written exactly the same (mind the caps!).
