The News template in the example site shows how to read feeds and show them, but it uses a DataGrid to do this, not a PageList.
You could create in-memory PageData items from scratch. The code in the MultiPage property, found on EPiCode ( http://www.coderesort.com/projects/epicode/browser/Intergen.EP.MultiPageProperty/trunk/Intergen.EP.MultiPageProperty/Intergen/SpecializedProperties/PropertyMultiPage.cs ) shows how to do this.
You need an account on EPiCode (it is free) to log in.
