Playing around with undo & redo functionality on WP7

Following on from my previous post about 'undo, redo, undo, redo' I thought I would port this to WP7, I say port more a case of re-compile. What follows is an example of simple WP7 app using undo-redo functionality, whether this is any use for a real-world Wp& is up for debate.I pushed the code out to GitHub here, the only explicit changes required was a WP7 solution & project files. I also added support for INotifyPropertyChanged...

An ORM would have saved time...

I've just finished working on a WPF, a pretty standard inventory system for widgets & gadgets. A hierachurial structure to the data that lends its self to a tree-view structure - essentially each node has a parent-child relationship, where a node can have multiple child nodes and each node has a reference to it's parent. The app is a simple a CRUD application with some UI tweeks on how the data was to be displayed - visualising the modified nodes in the tree and hows these affected the parent node.What made this interesting was the fact...
