POPUP Element
[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 It has been superseded by MediaPlayer.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.]
The POPUP element provides a way for users to select items from a list. These items can be specified by using ITEM elements as children of the POPUP element. The POPUP element is identical to the LISTBOX element except the default value of the popUp attribute is true. When popUp is set to true, the control is displayed only when the show method is called, and its width is set to the width of the content (the ambient width attribute is ignored). The control is hidden automatically when the user selects an item from the list or when the dismiss method is called.
Note
This element requires Windows Media Player for Windows XP or later.
