I'm wondering how to do this. I know you can hide a field by setting Visible to No. But by doing this, the ability to give the field a Control ID also disappears. Basically, I need a field that is connected to a SharePoint column. This field needs to be hidden from plain sight. But I need it to have a Control ID so I can populate it with information using jquery. This information will then be used by the workflow to continue with whatever it has to do.
