ACC2000: Dirty Property Not Recognized on Unbound Forms

ID: Q208908

The information in this article applies to:
Moderate: Requires basic macro, coding, and interoperability skills.


SYMPTOMS

When you reference the Dirty property of an unbound form (a form that is not based on a table or query), you may receive the following error message:

Run-time error '2455': You entered an expression that has an invalid reference to the property Dirty


CAUSE

The Dirty property is unavailable on unbound forms. The Dirty property was intended to indicate if the current record in the form's recordset is in edit mode. Because an unbound form has no recordset (the RecordSource property is blank) the Dirty property is not available.


RESOLUTION

Set the RecordSource property of the form to a table, query, or SQL statement.
