In Windows Forms, ListBox control is used to show multiple elements in a list, from which a user can select one or more elements and the elements are generally displayed in multiple columns. In ListBox, you are allowed to style the border of the ListBox using BorderStyle Property of the ListBox which makes your ListBox more attractive. You can set this property in two different ways:

1. Design-Time: It is the easiest way to style the border of the content present in the ListBox as shown in the following steps:

  • Step 1: Create a windows form as shown in the below image:
    Visual Studio -> File -> New -> Project -> WindowsFormApp
  • Step 2: Drag the ListBox control from the ToolBox and drop it on the windows form. You are allowed to place a ListBox control anywhere on the windows form according to your need.
  • Step 3: After drag and drop you will go to the properties of the ListBox control to style the border of the ListBox.


2. RunTime: It is a little bit trickier than the above method. In this method, you can style the border of the ListBox control programmatically with the help of given syntax:

public System.Windows.Forms.BorderStyle BorderStyle { get; set; }

Here, BorderStyle indicates the value of the BorderStyle and the values are:

  • Fixed3D: For 3-D border.
  • FixedSingle: For a single line border.
  • None: For no border.

It will throw an InvalidEnumArgumentException if the value of this property does not belong to BorderStyle. The following steps show how to style the border of the ListBox dynamically:

  • Step 1: Create a list box using the ListBox() constructor is provided by the ListBox class.
    // Creating ListBox using ListBox class constructor
    ListBox mylist = new ListBox();
  • Step 2: After creating ListBox, set the BorderStyle property of the ListBox provided by the ListBox class.
    // Setting the BorderStyle of the ListBox
    mylist.BorderStyle = BorderStyle.Fixed3D;
  • Step 3: And last add this ListBox control to the form using Add() method.
    // Add this ListBox to the form


    using System;
    using System.Collections.Generic;
    using System.ComponentModel;
    using System.Data;

    namespace WindowsFormsApp26 {
    public partial class Form1 : Form {
        public Form1()
        private void Form1_Load(object sender, EventArgs e)
            // Creating and setting 
            // the properties of ListBox
            ListBox mylist = new ListBox();
            mylist.Location = new Point(287, 109);
            mylist.Size = new Size(120, 95);
            mylist.BorderStyle = BorderStyle.Fixed3D;
            // Adding ListBox control to the form
