Introduction

In this blog we will see how we can fill ListBox with ListBoxItems using entity framework.

Step 1: Create ASP.NET Web Application

Form1.cs

  1. using System;
  2. using System.Collections.Generic;
  3. using System.ComponentModel;
  4. using System.Data;
  5. using System.Drawing;
  6. using System.Linq;
  7. using System.Text;
  8. using System.Threading.Tasks;
  9. using System.Windows.Forms;
  11. namespace WindowsFormsApplication1
  12. {
  13. public partial class Form1 : Form
  14. {
  15. public Form1()
  16. {
  17. InitializeComponent();
  18. }
  20. EmployeeDBEntities emp = new EmployeeDBEntities();
  21. private void btnForward_Click(object sender, EventArgs e)
  22. {
  23. listBox2.Items.Add(listBox1.SelectedItem);
  24. int i = 0;
  25. i = listBox1.SelectedIndex;
  26. listBox1.Items.RemoveAt(i);
  27. }
  29. private void btnBackward_Click(object sender, EventArgs e)
  30. {
  31. listBox1.Items.Add(listBox2.SelectedItem);
  32. int i = 0;
  33. i = listBox2.SelectedIndex;
  34. listBox2.Items.RemoveAt(i);
  35. }
  37. private void Form1_Load(object sender, EventArgs e)
  38. {
  40. foreach (var p in emp.Employees)
  41. {
  42. listBox1.Items.Add(p.FirstName);
  43. }
  44. }
  45. }
  46. }

Output of the application looks like this
