    OData support in RadGridView for Silverlight and WPF: The Netflix Catalog

    The Open Data Protocol – the other Microsoft data access strategy along with WCF RIA Services, did not gain as much as popularity as its RIA cousin (yet!). But here in Telerik we want to give you as much freedom and power as possible and this means making it extremely easy for our clients to access and manipulate their data in applications built with our components. Our RadDomainDataSource is coming soon, but is only one piece in the puzzle of enhanced data support in our controls – starting with RadControls for Silverlight and RadControls for WPF Q3 2010 it’s as simple as pie...

    Real-time update of Sparklines inside RadGridView SL/WPF

    Since Q3 2010 Telerik introduced the RadSparklines control. These new controls have remarkable performance as Yavor already showed. Today we will continue the topic of performance, however, we will do it in the context of a more real-world scenario. One application of the sparklines is to show financial data. Recently Vladimir Enchev blogged about real-time updates in RadGridView. Since sparklines and grids go hand-in-hand together when visualizing data we decided to prepare a small demo showing how to integrate both controls while still maintaining very good performance: In our project we took the real-time grid demo and also added some sparklines to it to illustrate...

    Drag from external programs into you WPF applications using RadDragAndDropManager

    Since Q3 2010 we have introduced new drag mode, enabling native drag from and to your WPF applications. In this post I will show how to successfully perform drag drop operations from external program into your application through the RadDragAndDropManager API. This can be achieved in several easy steps:   1. Set RadDragAndDropManager.EnableNativeDrag=”true”. This will enable native operations (if your application runs in full trust). The easiest way to do this is set it in StartUp event.           private void Application_Startup(object sender, StartupEventArgs e)         {             RadDragAndDropManager.EnableNativeDrag = true;         }   2. Set the RadDragAndDropManager properties to enable the drop operation:   telerik:RadDragAndDropManager.AllowDrop="True" telerik:RadDragAndDropManager.DropQuery="FileListGrid_DropQuery" telerik:RadDragAndDropManager.DropInfo="FileListGrid_DropInfo"   and add the corresponding...

    Exploring the RadSparklines performance in WPF/Silverlight

    As we know, the RadSparklines are characterized by their small memory footprint, cleaner XAML and simple but powerful rendering. When looking at the sparkline controls in the context of a charting tool one has to note that they are much more simplified. They lack many of the visual elements, such as Axis lines, gridlines or striplines. This makes them much faster when rendered and very suitable when used in high data-intensity scenarios. One such scenario may be when using different types of sparklines bound to a ViewModel/class, which passes hundreds or even thousands of data points to the controls.   Since the RadSparklines...
