Example - How to Bind Lookup to Data

The following example shows how to bind a lookup editor to data created at runtime:

C#
VB.NET

using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;

public partial class Form1 : DevExpress.XtraEditors.XtraForm {
    public Form1() {
        InitializeComponent();
        // Binds the lookup to data.
        lookUpEdit1.Properties.DataSource = Employee.GetSampleData();
        // Sets the lookup's data fields.
        lookUpEdit1.Properties.DisplayMember = "FullName";
        lookUpEdit1.Properties.ValueMember = "ID";
        // Sets the lookup's value. Selects the first record.
        lookUpEdit1.EditValue = 0;
    }
}

public class Employee {
    public Employee(int iD, string firstName, string lastName) {
        ID = iD;
        FirstName = firstName;
        LastName = lastName;
    }
    public static List<Employee> GetSampleData() {
        return new List<Employee>() {
            new Employee(0, "Bart", "Arnaz"),
            new Employee(1, "Leah", "Simpson"),
            new Employee(2, "Arnold", "Schwartz"),
            new Employee(3, "William", "Zimmer"),
            new Employee(4, "Samantha", "Piper")
        };
    }
    // The 'ID' field must contain unique values.
    public int ID { get; private set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    [Display(Order = -1)]
