ACC2000: Changing Row Source to Table Doesn't Remove Value List

• Microsoft Access 2000

SYMPTOMS

If you try to change the RowSourceType property of a combo box from a value list to a query after you've saved, closed, and reopened a form, the following behavior occurs:

• The RowSource property of the form will retain the values in the value list.



• The drop-down list of the combo box on the form will contain the values from the query.



• A new query, named from the values in the value list, will appear in the Database window.

CAUSE

This behavior occurs if you do not clear out the value list before you create the query.

RESOLUTION

Make sure you delete the RowSource property before you create the query.
