Event Handling

## onMouseOver Event

This event occurs when the mouse is moved over a cell. onMouseOver event passes the following parameters:

- id - id of the row;
- ind - index of the cell.

            grid.attachEvent("onMouseOver", function(id,ind){});

The event can be used to attach any kind of custom tooltips to the grid.

Returning false from event handler will block tooltips of grid, it can be used if you are using complex HTML content inside cell of the grid, which may have their own tooltips.
