Usually in any business application there is a big set of
control elements which often implement complex functionality and can confuse a
user. To make a user’s work easy, there are various types of help in almost
every application. These helps are shown in a variety of ways: labels and
images on a form, audio and video resources, etc. However, the most popular are
tooltips which are displayed as a result of a mouse cursor hovering over a
control element. This kind of help is very user-friendly because it allows us to
use the maximum space on a form (just necessary help is displayed).
Tool tips support is already implemented in both Windows
Presentation Foundation and Silverlight and there is no need to make additional
efforts to realize similar behavior. However, you should not expect that, in
Silverlight, there are fewer capacities to work with tool tips than in WPF.
Nevertheless, existing functionality is enough to create your own scenarios of
work with tool tips.
