VB.NET ScrollBars Control

A ScrollBar control is used to create and display vertical and horizontal scroll bars on the Windows form. It is used when we have large information in a form, and we are unable to see all the data. Therefore, we used VB.NET ScrollBar control. Generally, ScrollBar is of two types: HScrollBar for displaying scroll bars and VScrollBar for displaying Vertical Scroll bars.

Let's create a ScrollBar control in the VB.NET Windows form using the following steps.

Step 1: The first step is to drag the HScrollBar and VScrollBar control from the toolbox and drop it on to the form.
