Out of the Grid Events Hnds: Know the selected Row

I need a instruction of the style:   CurrentRow := LiveGrid.SelectedRow;

That returns the current selected Row. 

The event handlers of the LiveGrid, include normally the current row as ARow. But I need query the LiveGrid from out of these event handlers. 

Thanks. 

The FocusedCell returns the cell that is focused and selected.

even with SelectionMode := smSingleRow; ?

Yes, then you can use FocusedCell.Row
