Vista - XAML in WebPart

Hi,

This might be a silly question but is it possible to build a
application using XAML and put it inside a ASP.NET 2.0 web part
control? I want the features of web parts in 2.0 but build what sits
inside the web part using XAML.

Thanks, Rick

In the moment, WPF integration in HTML is possible only through an
IFRAME. It works fine with ATLAS, so there's no reason it won't work
with Webparts too.

Just wrap your IFRAME in a webpart, and set the SRC of the IFRAME to the
URL of the XBAP application, or to the loose XAML file.

That will work in IE only though.

Thanks for the reply Laurent..

I have one more question..

If had two xbap applications running on one web page (my example would
be 2 web parts each containing a xbap app) and have them communicate to
each other? So if i selected something in one xbap app i could pass
this to the other?

Thanks, Rick

That's not currently possible. XBAP applications running in IFRAMEs
(which is currently the only way to integrate them in a HTML page) are
running in their own isolated process. To let them communicate, you
would have to use some sort of interprocess communication, which is
obviously not possible in the Sandbox. Also, since they cannot
communicate with their HTML (JavaScript...) environment, any sort of
inter-XBAP communication has to go through the server.

This last possibility exists, but it's cumbersome. It implies a mailbox
running on the server, and both XBAPs polling the server to check if
there is a new message in the mailbox.

I have a prototype online exploring (amongst other things) communication
between XBAPs running in different windows. It's exactly the same
mechanism as if they are running in different XBAPs.

Note that if the XBAPs come from different domains, even web service
based communication will be impossible.
