Property Value

Type: System.String

A string that represents one or more URL filter options for the dialog box.

The Filter property is used by the EditValue method when calling the BuildUrl method, which displays the URL selection dialog box to the user at design time.

The Filter property default value indicates two URL filters for the dialog box: one for XML data files (*.xml) and another for all files (*.*).

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:

"XML Files (*.xml)|*.xml|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 XML Files (*.xd1; *.xd2)|*.xd1;*.xd2|All Files (*.*)|*.*".
