Dashboard prompt save from editable cell

So I created a dashboard that allows the user to specify label qty in a gridview. This is just a static column and doesn’t pull data from any where. In my customization, I went and set this field to be editable from customization wizard -->Modify Extended Properties, and set readonly to false. However, when the user close out of the dashboard, it is prompting them if they want to save. Is there anyway I can have this prompt not display?
