## Declaration

Source position: forms.pp line 229

`published property TScrollBox.AutoScroll : Boolean default True;`

## Description

AutoScroll is a Boolean property which indicates if scroll bars are automatically displayed or hidden on the control as needed. The default value for the property is True in TScrollBox.

Changing the value for the property causes the Visible property in both HorzScrollBar and VertScrollBar to be updated (if needed). When set to True, the UpdateScrollBars method is called to calculate the page, range, and visibility for the scroll bars. When set to False, the HideScrollbars method is called to reset and hide the scroll bars (when assigned).
