SelectionItemPattern.ElementSelectedEvent Field

Identifies the event that is raised when a call to any of Select, AddToSelection, or RemoveFromSelection results in a single item being selected.

Namespace:  System.Windows.Automation
Assembly:  UIAutomationClient (in UIAutomationClient.dll)

public static readonly AutomationEvent ElementSelectedEvent

This identifier is used by UI Automation client applications. UI Automation providers should use the equivalent field in SelectionItemPatternIdentifiers.

In the following example, event listeners are declared for the SelectionItemPattern events.

///-------------------------------------------------------------------- 
/// <summary> 
/// Subscribe to the selection item events of interest. 
/// </summary> 
/// <param name="selectionItem">
/// Automation element that supports SelectionItemPattern and is  
/// a child of a selection container that supports SelectionPattern 
/// </param> 
/// <remarks> 
/// The events are raised by the SelectionItem elements,  
/// not the Selection container. 
/// </remarks> 
///-------------------------------------------------------------------- 
private void SetSelectionEventHandlers
    (AutomationElement selectionItem)
{
    AutomationEventHandler selectionHandler =
        new AutomationEventHandler(SelectionHandler);

    Automation.AddAutomationEventHandler(
        SelectionItemPattern.ElementSelectedEvent,
        selectionItem,
        TreeScope.Element,
        SelectionHandler);
    Automation.AddAutomationEventHandler(
        SelectionItemPattern.ElementAddedToSelectionEvent,
        selectionItem,
        TreeScope.Element,
        SelectionHandler);
    Automation.AddAutomationEventHandler(
        SelectionItemPattern.ElementRemovedFromSelectionEvent,
        selectionItem,
        TreeScope.Element,
        SelectionHandler);
}

private void SelectionHandler(object src, AutomationEventArgs e)
{
    // TODO: event handling
