For the XtraGrid control, the SelectionChangedEventArgs class provides data for the ColumnView.SelectionChanged event. The event’s ControllerRow parameter identifies the handle of the row whose selection state has been changed. In specific instances, the entire collection of selected rows needs to be refreshed (for instance, when the grid’s data is re-sorted, re-grouped or filtered). In this instance, the ColumnView.SelectionChanged event fires, and its SelectionChangedEventArgs.Action parameter is set to CollectionChangeAction.Refresh and the ControllerRow parameter contains the GridControl.InvalidRowHandle property’s value.
The following code snippet (auto-collected from DevExpress Examples) contains a reference to the ControllerRow property.
