Now, when i heard about this a few weeks back, i though, meh. interesting, but meh. I had not seen any demos of it or though of what it could do. Then this morning, i clicked the link to the demo (might not load immediatly, and may take some time), and when it fully loaded, and i started to play around i actually was speachless! Its called DataGrid for WPF and its rocks! Ohhh, and its FREE. I am not sure if its using the WPF/E (Windows Presentation Foundation, Everywhere) so it may only work on IE, but if it is Everywhere, i may be using this for something… :)
