Public Class LookUpColumnInfo
The following members return LookUpColumnInfo objects:
The LookUpColumnInfo class represents a single column for a LookUpEdit control. The collection of columns is specified by the RepositoryItemLookUpEdit.Columns property and this represents an instance of the LookUpColumnInfoCollection class. To add a column to the collection, see the LookUpColumnInfoCollection.Add method.
The most important property of the lookup column is LookUpColumnInfo.FieldName. This refers to the field whose values are displayed in the column. You can use the property either to bind the column to a specific field in the RepositoryItemLookUpEditBase.DataSource or define the column as unbound.
A lookup editor allows you to create columns for all fields available in the RepositoryItemLookUpEditBase.DataSource. For this purpose, see the RepositoryItemLookUpEdit.PopulateColumns method.
The following code adds two columns to the RepositoryItemLookUpEdit.Columns collection of a lookup editor. For each column we initialize its field, caption and width.
using DevExpress.XtraEditors.Controls;
//...
lookUpEdit1.Properties.Columns.Add(new LookUpColumnInfo("ID", "No", 20));
lookUpEdit1.Properties.Columns.Add(new LookUpColumnInfo("Name", "Customer Name", 80));
Imports DevExpress.XtraEditors.Controls
' ...
LookUpEdit1.Properties.Columns.Add(New LookUpColumnInfo("ID", "No", 20))
LookUpEdit1.Properties.Columns.Add(New LookUpColumnInfo("Name", "Customer Name", 80))
