2 wxGrid in a NoteBookPage : event problem

[sylvain[78]]

Hello,

I have a problem while using 2 grids side by side in a NoteBookPage : 
all events are sent to the last created grid.

The grid1 and the grid2 have both a double click event.

If the grid2 is created in second, then a double click in the grid1 will 
call the grid2 event function

Who can I do to call the rigth event function ?

Thanks,
Sylvain
