    I have a treeview that allows drag and drop. I'm able to move or copy branches server side in the "OnNodeDrop" event, from one node to another.  What I would like to do is when a user attempts to drag a node and drop it, before this happens popup a dialog that asks the user to Move, Copy or Cancel the operation.  Based upon that input response perform the necessary action.  What is the best way to implement this? Thanks

    Hello Pete,

    I've attached a sample project that demonstrates how you can achieve this functionality with the help of RadWindow. In the sample I've implemented a client-based drag and drop mechanism, which will preserve the transferred items after postback, which is the best and simplest approach when using RadWindow.
