Assembly:  UIAutomationClient (in UIAutomationClient.dll)

Public Shared ReadOnly TextSelectionChangedEvent As AutomationEvent

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

System_CAPS_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.
Dim onSelectionChanged As AutomationEventHandler = _
New AutomationEventHandler(AddressOf OnTextSelectionChange)
Automation.AddAutomationEventHandler( _
TextPattern.TextSelectionChangedEvent, targetDocument, _
TreeScope.Element, onSelectionChanged)
