SubForm.Requery Method (Access)
The Requery method updates the data underlying a specified subform by requerying the source of data for the subform.
You can use this method to ensure that a form or control displays the most recent data.
The Requery method does one of the following:
Reruns the query on which the form or control is based.
Displays any new or changed records or removes deleted records from the table on which the form or control is based.
Updates records displayed based on any changes to the Filter property of the form.
Controls based on a query or table include:
List boxes and combo boxes.
OLE objects, such as charts .
Controls for which the ControlSource property setting includes domain aggregate functions or SQL aggregate function.
If you specify any other type of control for the object specified by expression, the record source for the form is requeried.
If the object specified by expression isn't bound to a field in a table or query, the Requery method forces a recalculation of the control.
If you omit the object specified by expression, the Requery method requeries the underlying data source for the form or control that has the focus. If the control that has the focus has a record source or row source, it will be requeried; otherwise, the control's data will simply be refreshed.
If a subform control has the focus, this method only requeries the record source for the subform, not the parent form.
The following example uses the Requery method to requery the data from the EmployeeList list box on an Employees form:
