What is the Dependency property in WPF and Silverlight.

Why we required and where we can use it.

Thanks…

From the documentation:

The purpose of dependency properties
is to provide a way to compute the
value of a property based on the value
of other inputs. These other inputs
might include system properties such
as themes and user preference,
just-in-time property determination
mechanisms such as data binding and
animations/storyboards, multiple-use
templates such as resources and
styles, or values known through
parent-child relationships with other
elements in the element tree.

So they’re like normal properties, but their value can be automatically computed from the values of other properties.

There is a good article on dependency properties here:
