The Hidden Control is used to contain data in the Workflow that shouldn't be directly interacted with or seen by the agent, and is often used in similar situations to Variables - but with the benefit of having the value of the Hidden not being cleared upon record completion.
The Field isn't visible to the agent at all.
This Control is part of the Basic Control pack, and will always be available.
How To
Add a Hidden to the Page. The options can be configured in the Options tab of the Field Properties, and Formatting can be applied if desired.
Notes
The Hidden can be used to contain system or default data on particular Pages of a Workflow, as opposed to using a Variable which would be included on every Page.
As agents can't directly see or edit a Hidden, any change to their value has to be made by code (such as from a JavaScript - Button or Calculate), or from a mapping in a data Control (such as the External Data Source or Table).
The value of a Hidden is stored in tbl_Data even after the completion of the record, so are sometimes used to record the value of a Variable back to the database upon record completion for subsequent reporting or re-launch.
