ACC: Subform Is Not Updated

• Microsoft Access versions 1.0, 1.1, 2.0, 7.0, 97

SYMPTOMS

Novice: Requires knowledge of the user interface on single-user computers.

When you scroll through records in the main form, the subform is not updated. The records on the main form and the subform are not synchronized.

CAUSE

The subform is not linked to the main form.

RESOLUTION

You should use the LinkMasterFields and LinkChildFields subform control properties to link the main form and subform automatically. You can manually update the subform by pressing the F9 (recalculate) key.

STATUS

This behavior is by design.

MORE INFORMATION

Recalculation occurs automatically for controls that reference other fields on the same form or fields in subforms. Recalculation does not occur automatically for subform controls that only reference fields on the main (master) form or in other subforms.

This is because subforms notify the master form of any changes, but the master form does not notify the subforms of changes. Nor do subforms on the same main form notify one another of any changes.

REFERENCES

For more information about main form/subform relationships, search the Help Index for "linking subforms," or ask the Microsoft Access 97 Office Assistant.
