    Real-time update of Sparklines inside RadGridView SL/WPF

    December 10, 2010 Share
    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

    December 08, 2010 Share
    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

    December 06, 2010 Share
    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...

    Some insight on the Telerik Weather Station application

    November 26, 2010 Share
    We have recently uploaded the Weather Station demo showing some of Telerik controls for Silverlight in a great rich context. Following Kalin’s blog post announcing the main features, this one is to provide some notes on the technical side of the matter. Here is a list of the main features: Find client’s location upon startup and retrieve weather information if available. Store current locations and favorite ones in the local storage for proper loading on next startup of the application. Use two formats for weather values - Celsius and Fahrenheit. Search for custom location. Display brief location information (on smaller zoom levels) as well as...
