How do I make tree view editable but undeletable?

Question

I want the tree view editable while editing, but I want the records to be undeletable. How do I achieve this?

Answer 1

I think you are looking for this:

<tree delete="false">
   ...
</tree>

Add that sentence to the tag <tree> in the XML view, and users won't be able to delete the records, but they still will be able to edit them.
