Question

when I’m using ColorAnimation to change Background of control i’m using following syntax:

<ColorAnimation Duration="0:0:0.5" 
 Storyboard.TargetProperty="(Control.Foreground).(SolidColorBrush.Color)" 
 To="Black" />

I’m very happy it works but I couldn’t find any information about round braces in xaml syntax reference …

So could you please explain where does this syntax come from and what does the round brace actually mean?

It would be very helpful.
Thanks

Please see PropertyPath XAML Syntax:

The parentheses indicate that this
property in a PropertyPath should be
constructed using a partial
qualification. It can use an XML
namespace to find the type with an
appropriate mapping. The ownerType
searches types that a XAML processor
has access to, through the
XmlnsDefinitionAttribute declarations
in each assembly. Most applications
have the default XML namespace mapped
to the
http://schemas.microsoft.com/winfx/2006/xaml/presentation
namespace, so a prefix is usually only
necessary for custom types or types
otherwise outside that namespace.
propertyName must resolve to be the
name of a property existing on the
ownerType. This syntax is generally
used for one of the following cases:

• The path is specified in XAML that is in a style or template that does
  not have a specified Target Type. A
  qualified usage is generally not valid
  for cases other than this, because in
  non-style, non-template cases, the
  property exists on an instance, not a
  type.

• The property is an attached property.

• You are binding to a static property.
