I want to make a single field editable(Display mode.Edit) and make all other fields viewable (FormMode.View) in Powerapps.
Will the FormMode override DisplayMode of fields.?
In my case, when I tried, every fields get viewable when I give FormMode.View.
You cannot override Edit mode for View mode. You will need to use disable property of each of your Field on Form to disable it (read only).
