The documentation hints that you can, for example, change the mouse cursor during a drag operation in the OnClientNodeDragging event depending on if the cursor is over a valid or invalid drop location, and shows how to get the X/Y coordinates of the cursor. 

But, does anyone have an example of how you could translate the X/Y into an actual html element or control, to determine if the current location is valid or not?

Hi Sheryl,

Check out :
http://www.telerik.com/DEMOS/ASPNET/prometheus/TreeView/Examples/Functionality/DragAndDropNodes/DefaultCS.aspx

If you look at then aspx code, you will see the javascript function you need:
function onNodeDragging(sender, args)  
                {  
                    var target = args.get_htmlElement();      
                      
                    if(!target) return;  
                      
                    if (target.tagName == "INPUT")  
                    {          
                        target.style.cursor = "hand";  
                    }  
 
                    var grid = isMouseOverGrid(target)  
                    if (grid)  
                    {  
                        grid.style.cursor = "hand";  
                    }  
                }  
 

Thanks for listening!
