The best way is to use a wxSizer.
Set a sizer to your panel. Add the wxDataViewListCtrl to the sizer.

Another way is catching the EVT_SIZE all windows trigger.
Handle it for your panel. In this handler get the size of the panel an set it to the wxDataViewListCtrl if you want it to fill the whole panel.
