ScrollBars Control in VB.NET

The ScrollBars control in VB.NET allows the user to scroll through the contents of a form or a container control, such as a Panel or a GroupBox.

Syntax

<ToolboxItem(True)>
<DefaultEvent("Scroll")>
Public Class ScrollBar
    Inherits Control

Example

Public Class Form1
    Private Sub hScrollBar1_Scroll(sender As Object, e As ScrollEventArgs) Handles hScrollBar1.Scroll
        ' Perform some action here
    End Sub

    Private Sub vScrollBar1_Scroll(sender As Object, e As ScrollEventArgs) Handles vScrollBar1.Scroll
        ' Perform some action here
    End Sub
End Class

Output

There is no visual output associated with the ScrollBars control itself. The control provides the user with a visual indicator of the current position and range of a scrollable control.

Explanation

In the above example, we have defined two ScrollBars controls, hScrollBar1 and vScrollBar1, and added event handlers for the Scroll event. When the user scrolls through the contents of the form or container control using the scrollbar, the Scroll event is raised and the corresponding event handler is executed. You can perform some action in the event handler to update the contents of the form or container control.

Use

The ScrollBars control is commonly used in GUI applications to allow the user to scroll through the contents of a form or a container control, such as a Panel or a GroupBox. This is useful when the contents of the form or container are too large to fit within the available space on the screen.
