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...

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...

I’m happy to announce that with our upcoming service pack (Q3 2010 SP1) you will be able to sort, filter and load records on demand with WCF RIA Services and our VirtualQueryableCollectionView.   To enable this we’ve added two extension methods for EntityQuery<T> and now you can use directly VirtualQueryableCollectionView SortDescriptors and FilterDescriptors: var context = new NorthwindDomainContext(); var query = context.GetOrder_DetailsQuery().OrderBy(o => o.OrderID); var view = new VirtualQueryableCollectionView() { LoadSize = 10, VirtualItemCount = 100 }; view.ItemsLoading += (s, e) => { var queryToLoad = query .IncludeTotalCount(true) ...

The Telerik Silverlight teams have released various demo applications together with hundreds of examples to help you get started more easily with RadControls for Silverlight. The newest demo application, the Weather Station, will not only show you how to bind the Telerik Silverlight data visualization controls to real-time data, thus creating interactive and engaging user experience, but it might also help you win an Xbox 360. All you have to do to participate in the “What’s the temperature?” game is to:  Launch the Weather Station application Check the weather in your city Tweet the temperature and the name of your city. Use...

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...
