Form.Filter Property (Access)
You can use the Filter property to specify a subset of records to be displayed when a filter is applied to a form, reportquery, or table. Read/write String.
If you want to specify a server filter within a Microsoft Access project (.adp) for data located on a server, use the ServerFilter property.
The Filter property is a string expression consisting of a WHERE clause without the WHERE keyword. For example, the following Visual Basic code defines and applies a filter to show only customers from the USA:
Setting the Filter property has no effect on the ADO Filter property.
You can use the Filter property to save a filter and apply it at a later time. Filters are saved with the objects in which they are created. They are automatically loaded when the object is opened, but they aren't automatically applied.
When a new object is created, it inherits the RecordSource , Filter, OrderBy , and OrderByOn properties of the table or query it was created from.
To apply a saved filter to a form, query, or table, you can click Apply Filter on the toolbar, click Apply Filter/Sort on the Records menu, or use a macro or Visual Basic to set the FilterOn property to True. For reports, you can apply a filter by setting the FilterOn property to Yes in the report's property sheet.
The Apply Filter button indicates the state of the Filter and FilterOn properties. The button remains disabled until there is a filter to apply. If an existing filter is currently applied, the Apply Filter button appears pressed in.
To apply a filter automatically when a form is opened, specify in the OnOpen event property setting of the form either a macro that uses the ApplyFilter action or an event procedure that uses the ApplyFilter method of the DoCmd object.
You can remove a filter by clicking the pressed-in Apply Filter button, clicking Remove Filter/Sort on the Records menu, or using Visual Basic to set the FilterOn property to False.
When the Filter property is set in form Design view, Microsoft Access does not attempt to validate the SQL expression. If the SQL expression is invalid, an error occurs when the filter is applied.
