How to set the Visibility of ListBox in C#?

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 can set the visibility of the ListBox using Visible Property of the ListBox.
If the value of this property is set to true, then the Listbox control and its child control are visible on the screen and if the value of this property is set to false, then the Listbox control and its child control are not visible on the screen. The default value of this property is true. You can set this property in two different ways:

1. Design-Time: It is the easiest way to set the visibility of 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 set the visibility of the ListBox.


2. Run-Time: It is a little bit trickier than the above method. In this method, you can set the visibility of the ListBox control programmatically with the help of given syntax:

public bool Visible { get; set; }

Here, the value of this property is of System.Boolean type. The following steps show how to set the visibility 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 lstbox = new ListBox();
  • Step 2: After creating ListBox, set the Visible property of the ListBox provided by the ListBox class.
    // Setting the visibility of the listbox
    lstbox.Visible = false;
  • Step 3: And last add this ListBox control to the form using Add() method.
    // Add this ListBox to the form

    using System.Windows.Forms;
    namespace WindowsFormsApp28 {
    public partial class Form1 : Form {
        public Form1()
        private void Form1_Load(object sender, EventArgs e)
            // Creating and setting the 
            // properties of the label
            Label lb = new Label();
            lb.Location = new Point(243, 80);
            lb.Text = "Select post";
            // Adding label control to the form
            // Creating and setting the
            // properties of ListBox
            ListBox lstbox = new ListBox();
            lstbox.Location = new Point(246, 104);
            lstbox.Visible = false;
            lstbox.Items.Add("Software Engineer");
            lstbox.Items.Add("Project Manager");
            // Adding listbox control to the form
