ADD: Copy node on Drag And Drop TreeView
TreeView doesn't contain the logic for moving the nodes. This logic is implemented by the developer, either on the client, or the server, as demonstrated in the following demo: http://demos.telerik.com/aspnet-ajax/treeview/examples/functionality/draganddropnodes/defaultcs.aspx Therefore this is not a feature for the control itself, rather an implementation descision when using the control. In the demo code, if you change the following line: var sourceNode = sourceNodes[i]; to this one: var sourceNode = sourceNodes[i].clone(); the client drag and drop will be implemented as "copy".
