Description
Occurs when a key is released while the control has focus.
OnKeyUp also occurs when KeyUp is called.
Write an event handler for OnKeyUp to specify what happens when the control is in focus and a key is released.
Warning: When using a virtual (on-screen) keyboard on Android devices, do not rely on KeyEvents to detect pressed keys, especially text characters. However, KeyEvents detects keys such as
return and enter but it does not delete, depending on the target application. Be aware that other software input methods may never send KeyEvents regardless of the version.See Also
