Hi,
there is a method to move an entire subtree from one tree to another, like doing a drag and drop operation,, but done programmatically?

    Thanks in advance

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

Thanks for the sample.
I used it on my project and it works.
Just one question:
after moving the nodes, they cannot be moved with drag & drop operation.
There is a way to maintain this behaviour after the Cut & Paste operation?

   Thanks in advance
