5 May 20211 minute to read

The auto-scroll limit allows you to define the scrollable region of the Diagram while the page is getting auto scrolled. The AutoScrollLimit property of scroll settings class helps to limit the auto scrolling area. It includes the following options:

  • Infinity: Allows auto-scroll in all directions without any restriction.
  • Diagram: Allows auto-scroll within the Diagram content.
  • Limited: Allows auto-scroll within the specified area.

The default operation is Infinity.
