Hello Hristo,
the problem is not on the DataAdapter. I have been a lot of time looking at the page, and in the various events (type: given that nonetheless seemed to me the scroll, I shrugged and I looked the other rows) I noticed that the DataAdapter and there was “complete.”
I entered the table in the event “ready” the “updatebounddata” and then I appear all rows.
I do not know why, where depends on the problem, unfortunately I had to do it this way.
Many thanks Hristo.
