Contents

The text displayed within the panel is comprised of the text from the filters of individual columns, plus the filter that is not bound to any column. To access the filter display text, use the ColumnView.FilterPanelText property. You can provide custom filter display text for a filter condition when creating this filter condition in code (using the ColumnFilterInfo constructor which takes the ‘displayText’ parameter). It is also possible to provide a custom filter display for the overall filter criteria by handling the ColumnView.CustomFilterDisplayText event.
