KeyDown & MouseDown events by same Subroutine with many Handles..?

[nilesh16782]

hi all.
i have a datagridview in which i want to know which row is selected by mousedown or keydown..
so in both case i want to use only ONE subroutine which can give e.rowindex , e.colindex value of datagridview...

Example..

Private Sub xyz (s as sender, e as keydownaurguments, m as mousedownaurguments) handles keydown, mousedown
               '\\\\ code
end sub

Or if possible i want to execute both events in datagridview.cellenter events

Private Sub Datagridview_Cellenter(s as sender, e as ???) handles 1,2,3,.....
         msgbox e.rowindex
end sub

(Before post this thread i already fighted with error "because they do not have the same signature" )
so plz tell me how make its possible...
