    RadChart for SL/WPF: Data grouping and aggregation

    Howdy folks! The RadControls for XAML Q3 Beta1 is out and it features an updated version of the RadChart control. We receive dozens of feature requests every day and one of the more substantial ones is the ability to analyze data with RadChart. The feature I will describe today is a great step in that direction. I’m talking of course about data grouping and aggregation.   Just like grouping and aggregate functions are one of the major features of our GridView control they can be used with the charts as well (if you have the beta).

    Per-request object scope vs shared one

    Quite some people have been wondering – why does the Telerik OpenAccess ORM team suggest using a separate object scope per every HttpRequest in a web scenario or on a thread level in desktop apps. Doesn’t this lead to many set-backs? What happens with change-tracking, optimizing the DAL using cache, synchronization.. This post will be dedicated to explaining why the per-request approach is not only the better, but the obligatory one in most of the cases. Usually data-modifications are transaction-bound in 99% of the cases. When the scenario does not allow that e.g. we need several requests to do...

    Multi-Item Drag and Drop with the RadListBox for WinForms

    Earlier this week, I ran across a forum post asking about how one would go about creating multiple RadListBoxes that supported multi-item drag and drop. This sounded like a fun challenge, so I decided to take it on. Referencing an earlier forum post that described single-item drag and drop, I came up with the following solution. Calling DoDragDrop() immediately changes the mouse pointer and readies the RadListBox for the drag-and-drop operation. Originally, I had tried calling this function in the MouseDown event, but this lead to unpredictable clunky behavior due to the fact that DoDragDrop() was getting called before I had the chance to ...
