How do I hide the default Task columns like Priority and Status when displaying the task in the Display or Edit forms?
I have a custom workflow in SharePoint 2010, built using VS 2012. I use the CreateTaskWithContentType activity. My custom content type has it's own columns which I want to display when the user opens the task, but I don't need them to enter any values for the default columns, so I prefer to hide them. I've tried both the Hidden and ShowInDisplayForm attributes without any success. Any ideas?
