Hi Nitin Thokare
well there's simple solution to your issue...
GC have add_action - http://www.grocerycr...ions/add_action
here if u can give your url that will print the row.. if its simple .. u can just say $crud->add_action('print', 'path_to_icon', 'controller_name/print');
it will add id to the url automatically.
if in case you want to have a custom url - u can have take advantage of url_callback
As for the print button in the view / read ...
u need to add the same and its base functionality in the gc template (for ex. flexigrid) .. which ever u prefer for the same.
