It depends on what exactly you need and what logic is inside the method.
For example, if the method depends on content of the form, it clearly can't be used outside this form.
Otherwise you can write a similar method on the view and execute it after fetching the data.
Or, if you want to be able to filter by the value, you can write a computed column. But then you can't reuse any code of the method, because the method is written in X++ while a view is a piece of T-SQL code. You would have to rewrite the display method to SQL, which might but doesn't have to be possible.
Next time, please provide more details about your requirement, so we can immediately jump into what you need.
