AutomationPeer.HasKeyboardFocusCore method

Applies to Windows and Windows Phone

Provides the peer's behavior when a Microsoft UI Automation client calls HasKeyboardFocus or an equivalent UI Automation client API.

Syntax


protected:
virtual bool HasKeyboardFocusCore()

Parameters

This method has no parameters.

Return value

Type: System.Boolean [.NET] | Platform::Boolean [C++]

true if the element has keyboard focus; otherwise, false.

Remarks

The "Core" methods are the standard implementations that perform the default action of an associated UI Automation client-callable method. You can override any of the "Core" methods to return alternative values in a custom automation peer. In this case, HasKeyboardFocusCore is invoked any time that HasKeyboardFocus is called.

The standard implementation at the AutomationPeer level checks whether the owner has focus, and always returns false if the owner isn't focusable. FrameworkElementAutomationPeer expands this behavior somewhat because it adds awareness of owner characteristics that rely on the owner being a Control subclass. Test the existing return value in the peer that you are using or overriding and then override that behavior if necessary.
