I have looked at XamDataTree but could not find a suitable event to prompt user before deleting a node for the conformation. Can you please help?
Hello,
You can achieve the functionality you are looking by inheriting the XamDataTree class. You can, after that, override OnNodeDeleting(which is cancelable) and implement a custom validation, before the actual deletion.
To illustrate this I have prepared a sample application, please find it as an attached file.
