TreeView is a very old component in the library so it doesn't comply with some of the standards that the library has developed over its existence. Property labelElId should actually be marked private and have an leading underscore in its name, but that convention came later.

TextNode will ignore any value you give labelElId, it will force its own name. You can read the assigned id value from it, but you can't force a value into it.

See:

http://developer.yahoo.com/yui/treeview ... properties

about how to store custom properties in a tree node and a few headings later, in responding to events, how to retrieve them.

BTW, a plain number is not a valid value for an id, they should be proper identifiers, starting with a letter or underscore and followed by letters, underscores and numbers. Most browsers won't complain, but some obscure feature might fail.

Regarding,

1) If the value used were to be assigned to a DOM element ID, it should be a valid identifier, if it is a custom value with no relation to any DOM element ID then you are completely free to use any value and you may name it anyway you want.

I can't help you much regarding how to use the context menu. TreeView is my thing, the rest, I am not sure.

The example you're using sets the variable oCurrentTextNode when the ContextMenu shows. So if you're using the code from the example you'll have this object, which is the node, so you can get the id and do what you want with it before you remove the node. It should be pretty straightforward.

But haven't you followed Satyam's suggestion of storing the database id in a custom property above? Then surely you can get the id from there?

So in your deleteNode function (or whatever you're calling it - that's what it is in the example), oCurrentTextNode is an object. The things you list ("TextNode (1): first folder" etc) are string representations, but the object has all sorts of properties. So will give you the id you need.
