Have a look at the VisualTreeHelper (I think that's it's name, I'm not
near a real internet connection - am on a cruise ship anchored off
Geraldton!) which has some static methods for finding child or parent
elements etc

I should have checked first, apparently it's not supported. I don't
know how you SL guys can inflict so much pain upon yourselves :)
I suppose it could be created by something like this:
public static T FindResource<T>(this FrameworkElement element,
string name)
{
var resource = element.Resources[name];
if (resource != null)
{
return (T)resource;
}
var parent = element.Parent as FrameworkElement;
if (parent == null) throw new Exception();
return parent.FindResource<T>(name);
}

Hi Tony,
I presume Silverlight has a FindResource()? In WPF that walks up the
visual tree looking for the resource, so it should find the item on
the page.

Hmmm. That works if I have the resource specified as a
UserControl.Resource within the control, but not if the resource is
on the owning page – it comes back null.
The user control requires access to various ViewModel classes, as
there are combo boxes to populate, so I am reluctant to bind the
UserControl.DataContext to the PriceViewModel, as it is only one of
a number of similar ViewModels needed. But I will have a rethink
about this one.
The other thought was whether there was some way to centralise
access to ViewModel classes from within the application. That is,
has anyone managed to put their ViewModel classes in as
Application.Resources?

Subject: Re: Accessing page resources from user controls
var viewModel = (PriceViewModel)Resources["YourKey"];
Since your UC is inside the page it will get the resources from there.
Are you setting the ViewModel as the DataContext. If so, you can
also get it from there.
