[Obsolete("Use the TreeListControl.SelectionChanged event instead")] [Browsable(false)] public event TreeListSelectionChangedEventHandler SelectionChanged
<Obsolete("Use the TreeListControl.SelectionChanged event instead")> <Browsable(False)> Public Event SelectionChanged As TreeListSelectionChangedEventHandler
The SelectionChanged event's data class is TreeListSelectionChangedEventArgs. The following properties provide information specific to this event:
|Action||Gets an action which indicates how the grid’s selection has been changed. Inherited from GridSelectionChangedEventArgs.|
|ControllerRow||Identifies the row whose selected state has been changed. Inherited from GridSelectionChangedEventArgs.|
|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.|
|Node||Gets a node whose selected state has been changed.|
|OriginalSource||Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class. Inherited from RoutedEventArgs.|
|RoutedEvent||Gets or sets the RoutedEvent associated with this RoutedEventArgs instance. Inherited from RoutedEventArgs.|
|Source||Gets or sets a reference to the object that raised the event. Inherited from RoutedEventArgs.|
The event data class exposes the following methods:
|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.|
Each time the treelist’s selection is changed, the SelectionChanged event is raised. The event parameter’s GridSelectionChangedEventArgs.Action property indicates how the selection has been changed. The TreeListSelectionChangedEventArgs.Node property returns the node whose selected state has been changed.
The SelectionChanged event is not fired if the DataControlBase.SelectionMode is set to TableViewSelectMode.None.
