I have a simple DetailsView in ReadOnly mode. I have paging enabled
because I need to show more than one record.
When user clicks next/prev page (PageIndexChanged event) I need to get
the current record ID (that is not one of the displayed fields, so
..Cell(x) won't work).
I expected DetailsView.SelectedValue to do the job but it doesn't (it's
always Nothing).
How can I solve this? My code follows.
