Last week marked another great CodeStock, a two day developer conference in Knoxville, TN.  The organizer, Michael Neel, does a great job of juggling the speakers, schedule, and venue, and the show continues to get better and better! Telerik was once again one of the core sponsors of the conference, as we continue our wide and deep support of the developer community.  I also gave for presentations: Test Driven Development for T-SQL Windows Presentation Foundation for Developers Implementing M-V-VM in WPF (Have you tried our WPF Controls?) Test The Hard Stuff With JustMock  All of the code can be found on my blog’s...

The fastest chart for windows phone 7 is just around the corner and it is not only fast, it is also very easy to use. To prove how easy to use RadChart is, consider the following steps which take the developer from a blank phone page to a page with a working chart that visualizes real data. In short the steps are these: Create chart object -> Add axes -> add series -> bind series to data. That’s right RadChart will support data binding on day -1 (this is the beta so it is not day 1 yet). Now let’s dig right into it. First...

You probably know RadGridView for WinForms. It became a must for every serious business application for its great and widely used features – load-on-demand hierarchy, self-referencing hierarchy, grouping, sorting, filtering, exporting capabilities and many others. There is one more cool feature that will greatly improve the user experience of your application – our built-in drag and drop mechanism. This is the core feature of the application that we would like to introduce today, namely Telerik Checkers.   As the name implies, Telerik Checkers is an implementation of the standard Checkers game and follows most of its rules. The drag and drop restrictions and customizations are possible thanks to the...

RadChart allows you to programmatically filter its data using FilterDescriptors as demonstrated in our help topic. However there are scenarios where you would like to have more complex filtering. For a sample scenario where a Chart is drawn according to the filtered RadGridView’s data - read further. The Chart and the GridView will be populated with the same data source – List of Business Objects: public class MyDateObject   {       public double SampleValue { get; set; }       public DateTime Date { get; set; }   }     public class MyDataContext   {       public const int min = 20;       public const int max = 80;       public ObservableCollection<MyDateObject> List { get; set; }       Random r = new Random();       DateTime baseDate = DateTime.Today;         public MyDataContext()       {           this.CreateChartData();       }         private void CreateChartData()       {           List = new ObservableCollection<MyDateObject>();           for (int i = 0; i < 15; i++)           {               List.Add(new MyDateObject() { SampleValue = r.Next(min,...
