Grid : selecting rows across pages


I have a grid with 100 rows per page. I am on page 1 and I programatically select rows 1 to 300 , on navigating to
page 2 and 3, the rows does not appear selected.

I am selecting rows using selectRows(i, false, true);

Thanks in advance,

Please be sure that multi-selection was enabled in grid


working sample was sent by email.


I am using dhtmlxgrid v2.0.  I guess that should be the issue. 
I now override selectRow function to the one in v2.1 and it now works!

Thanks for the help.
