Fill ListBox with ListBoxItems using Entity Framework

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;  
  10.   
  11. namespace WindowsFormsApplication1  
  12. {  
  13.     public partial class Form1 : Form  
  14.     {  
  15.         public Form1()  
  16.         {  
  17.             InitializeComponent();  
  18.         }  
  19.   
  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.         }  
  28.   
  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.         }  
  36.   
  37.         private void Form1_Load(object sender, EventArgs e)  
  38.         {  
  39.   
  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
