This property assumes a value of "0" if the Scroll-Pane control is not visible, "1" if it is visible.

When the Scroll-Pane is hidden, all the visible controls inside are hidden as well.

When the Scroll-Pane is made visible, all the controls inside that don't have their Visible property set to 0 are made visible as well.

 

Example - Define a scroll pane initially invisible and make it visible on procedure division
