Getting value in .Net code behind for an additional parameter (not a form field)

I created an additional parameter that is not a form field control. Is there a way I can reference that parameter value in .Net code behind when using Form Designer for a process?

UPDATE: The additional data parameter may be updated and assigned the value of a form field.

Thank you,


Hi James,

The code behind can only access fields that are in the form. Hidden fields need to be created in order to access/modify data values.
