Fillable Fields in a View
I think you need editablefield module. once this module is enable you can set any fields editable in your view. So when you visit your view page or block you can edit the field value there itself..
Nice Ajax is implemented in here, so it works very nice.. You can set it like double click to edit..

NOTE - I am not able to link the module with original URL at drupal.org so you can search for it in google with same name.
