I explored XAML databinding with Amazon's REST API, inspired by a Channel 9 RSS reader example. The XAML code fetches data from Amazon and displays it. A key challenge was handling Amazon's default namespace, requiring a NamespaceManager for correct XPath queries. The provided example demonstrates the basic functionality, and it can be expanded upon.
I've encountered a crash in XAMLPad (May CTP) when animating the width of a MenuItem. Specifically, if I remove the "From" attribute in a DoubleAnimation within a SetterTimeline, XAMLPad crashes. I expected the animation to start from the MenuItem's default width. Is this the correct way to use DoubleAnimation without specifying "From"? The crash occurs in a specific context: the Timeline is defined within a Style applied to a HeaderTemplate's DataTemplate element for a custom-drawn control. See the linked XAML for a complete example.
