This class provides data for the FilterAutoGenerating event of the C1DataFilter control. The FilterAutoGenerating event gets fired before a filter is added to the FilterCollection. This event allows you to modify the automatically generated filters or to cancel the generation of filters. The listing below provides the details about the event data.

• The Property property gets the data item property for which the current filter is being generated.
• The currently generating filter can be accessed using the Filter property.
• The event can be cancelled using the Cancel property, when there is no need to generate filters for specific data fields.
