The MdbDataFileEditor.Filter property is used by the erload:System.Web.UI.Design.UrlEditor.EditValue method when calling the erload:System.Web.UI.Design.UrlBuilder.BuildUrl method, which displays the URL selection dialog box to the user at design time.

The MdbDataFileEditor.Filter property default value indicates two URL filters for the dialog box: one for Microsoft Access database files (*.mdb) and another for all files (*.*).

To specify a custom filter string, derive a class from the System.Web.UI.Design.MdbDataFileEditor class and override the MdbDataFileEditor.Filter property to return the custom filter string.

A filter string contains one or more filter options. Each filter option contains a description of the filter, followed by the vertical bar (|) and the filter pattern. The strings for different filtering options are separated by the vertical bar.

The following is an example of a filter string that contains two filter options:

"Microsoft Access Databases (*.mdb)|*.mdb|All Files (*.*)|*.*".

You can specify several filter patterns in a filter option by separating the filter patterns with semicolons. The following is an example of a filter string in which the first filter option specifies two filter patterns:

"Custom Database Files (*.db1; *.db2)|*.db1;*.db2|All Files (*.*)|*.*".
