    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...

    Hello everybody! I am Yavor Ivanov and I work in the DataVisualization team here at Telerik.  As Vladimir mentioned earlier in his blog post, the Q3 release focuses on dashboards and line of business applications and today I am happy to announce another result of this focus: the RadBulletGraph!     The Bullet Graph is created by Stephen Few and it is designed especially for dashboards. This little wonder is very data intensive and easy to read at the same time. In just one Bullet graph you can demonstrate both what your projected and your accomplished goals for a period are, specify qualitative...

    How to create Custom Appointments and Custom Appointment Dialog in Telerik ScheduleView

    November 25, 2010 Share
    A common scenario when using the ScheduleView control is to have custom appointments with additional properties that are not by default included in the standard Appointment class. In these cases simply extending the Appointment class is not enough, because we have some more requirements – we want our custom properties to support cancelation of editing (like the standard one does), we want to allow the user to edit the custom properties using the Appointment edit dialog and eventually to render values of the custom properties in the AppointmentItem or/and its ToolTip. In this article we will go through the following steps: Create a custom appointment...
