project 2010 - catching events row change or cell double click

Hi all,

i developed a ribbon on project 2010.

in my code behind i'm using different events like : Application_ProjectTaskNew ..  and others.

i didn't find how can i catch the event when the user move between rows on the project grid and event when the user double click a cell , the "Task information" windows opens.

is it possible?

thanks..

Thanks, Sharon.
