	Hi, I have version 5.3.5.25867 of the Diagram control. I want to build some functionality that will allow the user to click a node and copy that node including all its subordinates so that iit can be pasted as a child of another node on the same or a different diagram. I was looking at the copyselection but we are preventing the user to select the links so the paste will just paste the nodes and not the links. Clone of a ShapeNode (DiagramItem) will clone the node and not the subordinate nodes.... Please help, Alin

	Hi, I can add this (copying of a DiagramItemCollection) to our feature request list. For now you might clone the whole diagram by calling LoadFromString(SaveToString()), select in the second diagram all items that should be duplicated, and copy them to the original via the selection-copy methods. I hope that helps, Stoyan

	thanks for the quick reply. I'm going to try that... Question - how do I progarmatically select a node and all the subordinate nodes? How do I navigate the subordinate links/nodes and add them to the selection? Question - How would I connect the first node of the selection to my destination node? Can I use AttachTo? Thanks a lot

	Loop over the items returned by node.Query("children") and node.Query("links") and set their Selected property. Yes, you can use AttachTo if what you need is to make the copied node a subordinate in another group. I hope that helps, Stoyan
