We are using Telerik Web Controls for ASP.NET AJAX Q1 2011.
I have been looking at the online demo for ListBox / Drag-and-drop with RadTreeView. This is actually what we want. the only problem we have now that the drag and drop happens on server side. We want a treeview and a listbox able to drag and drop on client side. no server side code after page load. We want to drag a item from treeview to listbox. After dragging it should create a new listboxitem with the same text and value.
Additionally we also want to have the opportunity copy or move items from treeview to listbox and from listbox to treeview. Moving and copying items between listbox and treeview should happen only on client side.
