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 set the height and width of the ListBox in pixels using Size 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 set the size of the ListBox as shown in the following steps:
2. RunTime: It is a little bit trickier than the above method. In this method, you can set the size of the ListBox control programmatically with the help of given syntax:
public System.Drawing.Size Size { get; set; }
Here, Size indicates the height and width of the ListBox in pixels. The following steps show how to set the size 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 Size property of the ListBox provided by the ListBox class.
// Setting the size of the ListBox
mylist.Size = new Size(120, 95);
- Step 3: And last add this ListBox control to the form using Add() method.
// Add this ListBox to the form
this.Controls.Add(mylist);
Example:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace WindowsFormsApp25 {
public partial class Form1 : Form {
public Form1()
{
InitializeComponent();
}
private void Form1_Load( object sender, EventArgs e)
{
ListBox mylist = new ListBox();
mylist.Location = new Point(287, 109);
mylist.Size = new Size(120, 95);
mylist.ForeColor = Color.Purple;
mylist.Items.Add(123);
mylist.Items.Add(456);
mylist.Items.Add(789);
this .Controls.Add(mylist);
}
}
}
