The HoverPanel class provides an easy to use base AJAX control that allows quick access to server side content from a URL and embed it into the control's content. The control provides various visual customization aspects from shadows, transparency, the ability to drag it around and close it as well as pop up and auto hide.

The most prominent feature of this control is to provide auto-popup functionality that shows context sensitive content while hovering and hiding it when moving off.

For more details on how the control works, see the HoverPanel Windows topic. This control allows calling back to explict URLs either on the same page or calling other URLs within the same site that feed the content to be rendered in the hover panel control.
