MdbDataFileEditor Class
Assembly: System.Design (in system.design.dll)
An MdbDataFileEditor object is used at design time to select and edit a URL for a Microsoft Access database file (.mdb), and then assign the URL to a control property. For example, the AccessDataSource control uses the MdbDataFileEditor class at design time to set the value of the DataFile property.
Use the EditorAttribute attribute to associate the MdbDataFileEditor with a property. When the associated property is edited on the design surface, the designer host calls the EditValue method. The EditValue method uses the BuildUrl method, which in turn displays a user interface for selecting the URL, and then returns the URL that is selected by the user. The GetEditStyle method indicates the display style of the user interface.
Derive a class from the MdbDataFileEditor to define a custom editor for an Access database URL property. For example, a derived class can override the EditValue method, and then call the BuildUrl method with a custom Filter or Caption value.
The following code example demonstrates how to associate an instance of the MdbDataFileEditor class with a property that is contained within a custom control. When you edit the control property on the design surface, the MdbDataFileEditor class provides the user interface to select and edit an Access database file name for the property value.
