TextPattern.TextSelectionChangedEvent Field

Identifies the event raised when the text selection is modified.

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

public static readonly AutomationEvent TextSelectionChangedEvent
public static final AutomationEvent TextSelectionChangedEvent
public static final var TextSelectionChangedEvent : AutomationEvent
Not applicable.

Some text controls handle the text insertion point (cursor) as a zero-width text selection and might raise TextSelectionChangedEvent when the cursor is moved.

NoteNote:

To follow cursor movements, UI Automation clients are advised to keep track of insertion point changes by listening for corresponding UI Automation element events rather than depending on TextSelectionChangedEvent.

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

// Initialize a selection changed listener.
// The target selection is reflected in the client.
Automation.AddAutomationEventHandler(
    TextPattern.TextSelectionChangedEvent,
    targetDocument,
    TreeScope.Element,
    OnTextSelectionChange);
