There is a scenario where I would like to have users to enter some values in display mode and save them. The form should save the values entered into the columns. I am facing two issues here. One the list lookup control I use is not populating data in display mode and the second on save & submit button the values dont get saved in display mode.
why you call it display mode when you need to change/edit data? aka you need edit mode
why to complicate things and misuse display form for things it's not designed for?
you should rather use edit form and using rules make all the not-to-be-edited controls read only
