attribute_onchange

[The feature associated with this page, Windows Media Player SDK, is a legacy feature. It has been superseded by MediaPlayer. MediaPlayer has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer instead of Windows Media Player SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

When a skin attribute changes value, an event occurs that can be handled by an event handler. The name of the event handler is the name of the attribute followed by an underscore and "onchange", such as "value_onchange".
