We have a few applications developed by contractors where the data is not connected to a list column. Where is this data stored? Is there any way to get tot this data, if we needed to get to this data in a workflow>
there is a hidden list field named FormData which stores all the content of not connected controls in a XML structure.
if you've got assigned a name to the control you may address respective control's data by its name. otherwise controls are identified by unique GUIDs.
