Describes how a Popup control animates when it opens.
Assembly: PresentationFramework (in PresentationFramework.dll)
|The Popup control gradually appears, or fades in. This effect is created by increasing the opacity of the Popup window over time.|
|The Popup control appears without animation.|
|The Popup control scrolls from the upper-left corner of its parent. If the screen does not provide enough room to allow the Popup default behavior, the Popup scrolls from the lower-right corner instead.|
|The Popup control slides down or up into place. By default, a Popup slides down. However, if the screen does not provide enough room for the Popup to slide down, it slides up instead.|
