Sliders are typically the property of desktop applications. They provide the ability
for the users to filter and narrow without suffering the stress of a page reload.
Slider extender allows to upgrade an asp:TextBox to a graphical slider that allows
the user to choose a numeric value from a finite range. A further benefit of Sliders
is their excellent support for combination among similar data. When several Sliders
share the same range, they can be placed in parallel to show how the combined effect
looks like.
