In order to have richer examples, we have created a specific popup control - ZoomPopup (used in the "Business Cards" integration example as well as in the RadComboBox
"Item Scaling" example). Unfortunately, ZoomPopup
can be used for zooming popups only.
If you need to animate opacity instead of zooming, you will have to make it on your own. We will consider adding such a popup in the future.
The easiest way to achieve a popup that has opacity animation is by inheriting MS Form
and using its Opacity
property. Set the form FormBorderStyle
property to None
property to Manual
property to the rectangle of the popup. Then animate the Opacity
from 0 to 1.
You will have to use a mouse hook or a message filter to detect conditions for closing the popup (such as moving the mouse out of the area of the popup or receiving WM_ACTIVATEAPP).
is a top-level window, special care should be taken for the window activation (and the WM_NCACTIVATE message).
