ListView controls
When Scrolling is enabled, the user can scroll vertically when some of the items in a ListView control are not visible. When Scrolling is not enabled, the user cannot scroll.
To enable scrolling:
Select the Scrolling check box on the General page of the control’s Properties view.
The Scrolling property takes a boolean value. The following line enables scrolling when necessary in a ListView.
lv_1.Scrolling = TRUE
