WPF user controls interacting with each other

[Eps]

Hi,

I am writing an mp3 player using wpf, I have three user controls (media
library, media controls and a playlist). Obviously I need these to
interact with each other, I assume the best way to do this is to use
events right ?.

Can I raise an event on one user control and have one of the others
suscribe to it ? or do I need to have the main window suscribe to it and
then pass the message on to the target user control ?.

Any advice appreciated.

I don't think the controls should be interacting with each other at all.

Besides the controls, the program should have a data model — some kind of
data structures for the media library, one section of which represents a
playlist, and the current status of the player. The controls reflect the
current state of the data model by the means of databinding, and they change
the model with databinding and commanding. They do not have to know anything
of each other, or of the window they belong to.

I have a datable in the medialibrary control that contains (amongst
other things) the path of every song. Are you suggesting I create a new
object which encapsulates the datatable as well as exposing more
properties (like the play/pause/stop status and the current song, etc.)

I guess all the controls could then just bind to relevent properties of
the object.

I have played about a bit with data binding, how do you go about binding
to an objects property ?.
