• Data items

• Forms

• Pages

A comma-separated list of field names. The fields can be selected by clicking the AssistEdit button in the Value field of this property.

When the request form is in use, the user will be able to add other fields and set filters on these fields.

Even so, it may still be a good idea to use this property: if the underlying table has many fields, the occasional user of the report or dataport may not easily find the relevant fields to filter.

If you do not want the user to be able to put filters on other fields, you must remove the request form by using the UseReqForm Property of the report or dataport, or remove the tab for this data item, by setting a specific key.
