The SelectionChanged event's data class is GridSelectionChangedEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| Action | Gets an action which indicates how the grid’s selection has been changed. |
| ControllerRow | Identifies the row whose selected state has been changed. |
| Handled | Gets or sets a value that indicates the present state of the event handling for a routed event as it travels the route. Inherited from RoutedEventArgs. |

| Source | Gets the View that raised the event. |
The event data class exposes the following methods:
| Method | Description |
|---|---|
| InvokeEventHandler(Delegate, Object) | When overridden in a derived class, provides a way to invoke event handlers in a type-specific way, which can increase efficiency over the base implementation. Inherited from RoutedEventArgs. |
| OnSetSource(Object) | When overridden in a derived class, provides a notification callback entry point whenever the value of the Source property of an instance changes. Inherited from RoutedEventArgs. |
Remarks
Each time the grid’s selection is changed, the SelectionChanged event is raised. The event parameter’s GridSelectionChangedEventArgs.Action property indicates how the grid’s selection has been changed. The GridSelectionChangedEventArgs.ControllerRow property returns the handle of a data row whose selected state has been changed.
The SelectionChanged event is not fired if the GridControl‘s DataControlBase.SelectionMode is set to MultiSelectMode.None.
