| Run Time Interaction > Navigation and Scrolling > Mouse navigation |
When the user clicks a row, that row becomes current, and the RowChange event is fired.
The user can also use the mouse to manipulate the list's scroll bars, bringing cells that lie outside the list's display area into view. The vertical scroll bar governs rows; the horizontal scroll bar governs columns. The ScrollBars property controls which scroll bars are displayed, if any.
Scrolling always occurs in discrete cell units; the user cannot scroll on a per-pixel basis in either direction.
Note that the scroll bars do not change the current cell. Therefore, the current cell may not always be visible.
To respond to vertical scrolling operations in code, use the FirstRowChange event. To respond to horizontal scrolling operations in code, use the LeftColChange event.
