UIElement.OnAccessKey(AccessKeyEventArgs) Method
Definition
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Provides class handling for when an access key that is meaningful for this element is invoked.
protected:
virtual void OnAccessKey(System::Windows::Input::AccessKeyEventArgs ^ e);
protected virtual void OnAccessKey (System.Windows.Input.AccessKeyEventArgs e);
abstract member OnAccessKey : System.Windows.Input.AccessKeyEventArgs -> unit
override this.OnAccessKey : System.Windows.Input.AccessKeyEventArgs -> unit
Protected Overridable Sub OnAccessKey (e As AccessKeyEventArgs)
Parameters
The event data to the access key event. The event data reports which key was invoked, and indicate whether the AccessKeyManager object that controls the sending of these events also sent this access key invocation to other elements.
Remarks
There is no actual AccessKey event in the UIElement class, or elsewhere, which you can raise or attach handlers for. Instead, the event is originated via a dedicated manager class, AccessKeyManager, which post-processes all input to search for access keys that are applicable to the entire input model.
Notes to Inheritors
The default implementation of this method in UIElement sets keyboard focus to this element (by calling Focus()). Implementations should perpetuate this behavior if they are focusable, because it is an expected behavior for accessibility scenarios. Note that the base implementation does nothing with the passed event data and raises no further event; it just sets the focus.
