    Incremental loading with RadDataGrid in your Windows 8.1 XAML app

    December 18, 2013 Share
    Fast and fluid experience is one of the most important characteristics of a Windows 8 application. However, when dealing with large amount of data, it is not always possible to get the entire data set downloaded and visualized in a fast and fluid manner. Such scenarios call for a more incremental (sequential) data loading approach and with our Q3 2013 release RadDataGrid makes this task easy to implement.

    Controlling current culture in your XAML Windows Store apps

    Using commands with RadDragAndDropManager for WPF and Silverlight

    December 15, 2010 Share
        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...
