I for one welcome the proposed new Start button experience as well as anything else they manage to get into this next release (full disclosure, I was at Build and use that tablet almost as much as my work laptop... my iPad has become a glorified Kindle), especially if it has more developer goodness included.

    Filtering Collection Properties with RadGridView for Silverlight and WPF

    December 05, 2011 Share
    By default, RadGridView will not be able to filter properties which are IEnumerable. However, with two of its features you can easily add this custom functionality. The first feature you need to use are the Custom Filtering Controls which I have explained in one of my earlier blog posts so I will not go into detail here.
