    Create Special Slots in Telerik ScheduleView for WPF

    With the new SP1 release of Q3 2010 we added a new feature to RadScheduleView that helps you customize every slot in a different way. To do that you should create an instance of the Slot class, set its Start and  End  properties, the Resources property - with this property you can define in which resource column the slot will be displayed, and the RecurrencePattern property - with this property you can define whether the slot will be displayed for repeating days or events like Christmas, WeekendDays  and Birthdays. For example let's say that we have a schedule control and want to customize the days that...

    Controlling TreeView’s ExpanderStyle Dynamically

    Sometimes the TreeView is used in scenarios where the expander style must be styled in custom fashion. Prior 2010 Q3 SP1 there was no easy way to dynamically change the expander style of the TreeView or particular item. TreeView’s ExpanderStyle So we decided to extend the functionality provided by the TreeView. Prior this enhancement changes to the ExpanderStyle property during runtime would not affect already visible items. The property now supports dynamic values and data binding. This way you can easily change the style of the expander of all items in the hierarchy during runtime. Item’s ExpanderStyle Working only with the TreeView’s ExpanderStyle...

    Programatically selecting visual items with the new Interactivity API in RadChart for Silverlight / WPF

    Hi everyone! As you know RadChart supports selection and hover interactivity effects and 2010.Q3 release exposes an API that allows you, the developer, to control it. Now I am going to show you how you can select any number of items only by moving your mouse.   First let’s start with the rectangle selector that the user draws with its mouse. I have added a canvas on top of the Radchart to hold the rectangle. We need to listen to MouseLeftButtonDown, MouseMove and MouseLeftButtonUp events to control the rectangle position and size. The tricky part is how to convert the size of the rectangle...

    Using commands with RadDragAndDropManager for WPF and Silverlight

        In this post I will demonstrate how to extend the Drag Drop functionality of the RadDragAndDropManager adding command support by using the attached behaviors extensibility. That way one can easily move the logic for the operation from the code behind into your model and work only with the Data object. To demonstrate the idea I will use scenario where items are being dragged between ListBoxes.   The behavior transforms the Drag Drop events into commands. It exposes the following properties: - DragCommand – executed when dragInfo event is raised. - DropCommand – executed when dropInfo event is raised. - DragCueTemplate – data template that defines the dragcue...

    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...
