I am trying to send my dynamically created silverlight 2 page/image to a an ASP.net web service to render it as an bitmap image.
I can see many examples how to get the XAML using javascript (see here) in version 1 of silverlight but I have a few differences.
a) I am using silverlight 2 RC1
b) I have dynamically add controls to the page in c#
c) I would prefer to use c# to get the new XAML to keep all the coed in one place.
does anyone know how to extract the XAML from a control or the page in c#?
Thank you
Update: This is now possible under silverlight 3 using a writable bitmap to save the XAML as a JPEG see my blog post here: http://blog.blueboxes.co.uk/2009/07/21/rendering-xaml-to-a-jpeg-using-silverlight-3/

Hi John, unfortunately there is not a method for a .ToXaml() on an element tree unfortunately. You can use VisualTreeHelper to build such a method and recurse through a particular element I suppose.

SilverlightContrib has a XamlWriter class that can extract the XAML from a live control.
It's free.
The link is: http://silverlightcontrib.org
The code would be something like:
// using SilverlightContrib.Xaml; var cb = new GroupBox(); StringBuilder sb = new StringBuilder(); XamlWriterSettings settings = new XamlWriterSettings(); using (XamlWriter writer = XamlWriter.CreateWriter(sb, false, settings)) { writer.WriteElement(cb); } string result = sb.ToString();
