I was wondering what kind of control Amazon has used to display text in their application for Windows Phone 7 ? It must be some kind of custom ones because if I remember correctly there's not support for FlowDocument, Run etc in WP7.
<Run> is supported on WindowsPhone7 - e.g. http://social.msdn.microsoft.com/Forums/en-SG/wpf/thread/ca27556a-a33b-4d4e-82b4-a0ed8596d6a1 - you can see Run used in lots of apps - e.g. the official Twitter app.
This question - Programmatically determining max fit in textbox (WP7) - analyses the Kindle UI control a little bit - it leads me to think that Amazon are using a TextBlock control for the main page, and are doing some manual calculations to work out how many words are on the current page.
Kindle ebooks are primarily HTML (output of conversion from multiple formats), so it would be some kind of WebBrower control.
They haven't detailed this publicly.
I strongly suspect that they have their own controls to wrap a canvas which they dynamically populate with the text and then animate with their own manipulation code.
