Get bound Odata Object from ListItem

Hi Folks,

I built a list with some bound items ... but not all of the OData attributes are bound because I do not need everything to be visible.

But when handle the onclick event on the listItems I need the additional attributes.

So my question is:

Do I have to bind ALL attributes (e.g .with hidden attributes in the control) or is there a way to get the bound OData object to the corresponding UI element and read the attributes there?

That would mean I have to do a lot of mapping to data I will never show the user!

Any suggestions on this?

Thank you in advance
