PopupControl Extender
The PopupControl extender allows you to easily enhance an existing control, such as a
TextBox, in your page with richer content that is hosted inside another control (most
often a Panel control). An important point to note here is that because most often this
richer content contains interactive element(s), using an UpdatePanel is highly recommend
to handle postback issues and make a responsive AJAX-style user experience. Table 8-11
displays the main properties of the PopupControl extender.
