    I'm trying to figure out how to use a Telerik ListBox control for an application that I'm writing. For some reason I can't view any of the Telerik demos (they're all timing out on me), and so I've been searching around this site for other help. I came across this page on drag-and-drop for the ListBox, and it looks really promising. However, in reading through the code on the page I came across their ProductToOrderConverter class. It inherits (or implements, I'm not sure which) from something called a DataConverter. What is that?? Even on this site I'm having a hard time finding any documentation on what the dataconverter class/interface is.

    Hello Rod,

    The DataConverter is abstract class that is used with DragDropManager's behaviors. DragDropManager helps you to implement Drag-Drop functionality in your application. You can read more information about it here. We provide and easy way to implement DragDrop in RadListBox via ListBoxDragDropBehavior. But you may need to drag an item from one RadListBox and Drop it in another one, which has a collection of other object types. In such scenarios you have to use a DataConverter implementation in order to be able to drop the data in the second RadListBox. The dragged data should be converted as described here. In our API Reference you may find more information about DataConverter class.

    Hopefully this helps.
