I did a search and couldnt find more info on this..
I created a Task List to keep track of various projects. The out of the box functionality has a check box which works with the 'Complete %' field.
Thing is, with my list items dont work on a % state. They are either in progress, or completed. Before using a Task List, I was using a normal list library and I had a 'Completed Date' date field which gets populated when the project is complete.
Is it possible for the check box to work with this field instead? And when a user checks the checkbox, to populate the 'Completed Date' field, rather than changing the 'Complete %' field?
