Binding last row in table to a label

[obs]

Hi all.

I have a label on my page and I want to bind it to a field in a table. The catch is that I want to bind it to the last row in the table.
I think I can use the custom binding, but I don't know how to bind to the last row. Any Suggestions ?

p.s. The page is tied to an SqlDataSource that retrieves the data from the above table.

Thanks in advance.
