VB.NET ListBox Control

The ListBox control is used to display a list of items in Windows form. It allows the user to select one or more items from the ListBox Control. Furthermore, we can add or design the list box by using the properties and events window at runtime.

Let's create a ListBox control in the VB.NET Windows by using the following steps.

Step 1: Drag the ListBox control from the Toolbox and drop it to the Windows form, as shown below.
