It looks like the event are still present, but not published. However, you can assign event handlers in your own code. For example:
grdMembers.OnClick := MyOnClick;
grdMembers.OnDblClick := myOnDblClick;
With the implementation like:
procedure TframeMemberList.myOnClick(Sender: TObject);
procedure TframeMemberList.myOnDblClick(Sender: TObject);
This works on Windows as well as Mac OS X (haven't tested on mobile devices)...
