OnCreateAutomationPeer ( ) : AutomationPeer

Returns a T:System.Windows.Automation.Peers.TreeViewAutomationPeer for use by the Silverlight automation infrastructure.
OnGotFocus ( RoutedEventArgs e ) : void

Provides handling for the GotFocus event.
OnItemsChanged ( NotifyCollectionChangedEventArgs e ) : void

Makes adjustments to the T:Microsoft.Silverlight.Testing.Controls.TreeView control when the value of the P:Microsoft.Silverlight.Testing.Controls.ItemsControl.Items property changes.

Private Methods

Méthode Description
ChangeSelection ( object itemOrContainer, TreeViewItem container, bool selected ) : void

Change whether a TreeViewItem is selected.
CheckForSelectedDescendents ( TreeViewItem item ) : void

Select any descendents when adding new TreeViewItems to a TreeView.
FocusFirstItem ( ) : bool

Focus the first item in the TreeView.
FocusLastItem ( ) : bool

Focus the last item in the TreeView.
HandleMouseButtonDown ( ) : bool

Provides handling for mouse button events.
HandleScrollByPage ( bool up ) : bool
HandleScrollKeys ( Key key ) : bool

Handle keys related to scrolling.
IUpdateVisualState ( bool useTransitions ) : void

Update the visual state of the TreeView.
OnItemContainerStylePropertyChanged ( DependencyObject d, DependencyPropertyChangedEventArgs e ) : void

ItemContainerStyleProperty property changed handler.
OnKeyDown ( KeyEventArgs e ) : void
OnSelectedItemPropertyChanged ( DependencyObject d, DependencyPropertyChangedEventArgs e ) : void

SelectedItemProperty property changed handler.
OnSelectedValuePathPropertyChanged ( DependencyObject d, DependencyPropertyChangedEventArgs e ) : void

SelectedValuePathProperty property changed handler.
OnSelectedValuePropertyChanged ( DependencyObject d, DependencyPropertyChangedEventArgs e ) : void

SelectedValueProperty property changed handler.
PropagateKeyDown ( KeyEventArgs e ) : void

Propagate OnKeyDown messages from the root TreeViewItems to their TreeView.

Because Silverlight's ScrollViewer swallows many useful key events (which it can ignore on WPF if you override HandlesScrolling or use an internal only variable in Silverlight), the root TreeViewItems explicitly propagate KeyDown events to their parent TreeView.

SelectFirstItem ( ) : void

Select the first item of the TreeView.
UpdateSelectedValue ( object item ) : void

Update the selected value of the of the TreeView based on the value of the currently selected TreeViewItem and the SelectedValuePath.
