display different cursor if over invalid drop area?

[Sheryl Landon]

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!
