Thanks Dmitry,
I'm already using those methods. The problem is that I want to use a Button
and set a binding in the "enabled" property
something like
enabled="{myCursor.beforeFirst}"
But this is useless since I must go outside the collection to make the
button enalbed or not.
I want the "previous" button disabled as I reach the first item and the
"next" button disabled as I reach the last item
Hope this is more clear.
Thanks
C.

Use this methods to check are you already at the end or at the start of
collection
to move use moveNext() and movePrevious(). after checking
