I have two gridviews I want to drag and drop rows from one to the other. I cannot get any of the drag event to fire when I select a row and drag with the mouse. The only ones that seem to fire are the DragQuery and DragInfo, neither of which will give me drag effects. All the sample projects provided are for out of date code and need to have a half dozed helper classes. Are there no simple methods to implement this with the new Radgrid?

Hi OverCoded,

When using Telerik DragAndDropManager the drag operations will be controlled by this four events:
- DragQuery
- DragInfo
- DropQuery
- DropInfo
For more information please check this article - http://www.telerik.com/help/silverlight/raddraganddrop-events-overview.html

If you need to use the DragEnter/Leave, Drop, etc. events you need to use WPF build-in DragDrop mechanisms. More Information could be found in this article - http://msdn.microsoft.com/en-us/library/ms742859.aspx.

So, in order to achieve the desired behavior with Telerik DragAndDropManager you can check the attachment project where I have demonstrated simple way of achieving it.

Currently, we are also working on some improvements in this area which will allow achieving with just few lines of code.

Let me know if have any further questions.

Best wishes,
