Hi Andrea,
Sorry for the inconvenience caused.
We would like to let you know that, currently we don’t have a public method to move an entire sub tree from one tree to another tree without drag and drop. But we can achieve it programmatically and we have prepared a custom sample based on your requirement. We have attached the custom sample in the following location.
http://www.syncfusion.com/uploads/user/forum/118491/Treeview-730729990.zip
In this sample we have written the code in a button click event. In the button click, we have cut and paste the selected node by triggering “keydown” event and make control key as true. Then we have used the key code “88” to cut and “86” to paste the node. Then assign the value for “_cutCopyNodeText”. Finally trigger the event.
Please let us know if you have further queries.
Regards,
Saranya.S
