I tried that, and just like the other things I tried, it just gives me an
empty browser window. Here is my exact code from my files:

You will notice that the code in my DataBound eventhandler attempts to set
the Visible property of some of the controls in the PagerTemplate. To make
sure this was not the reason for the empty browser window (although the
ItemTemplate and the other PagerTemplate controls should show anyway), I
tried it with that line commented out and with the whole DataBound event
commented out, but I still receive an empty browser window. The
Response.Write() at the end of the Refresh() method was a check to make sure
my DataSource was not empty, and it wasn't (the Response.Write() output a
3). Why can't I get this thing to work? I don't have any problems when I
don't use the PagerTemplate. Thanks.

the PagerTemplate, not the ItemTemplate. Thanks.
Handle the event DataBound
fviewPhotoAlbum_DataBound(...)
Dim pager as FormViewRow = fviewPhotoAlbum.BottomPagerRow
Dim myControl as Control = pager.FindControl('lnkPhotoAlbum')
Dim btn as LinkButton = CType(myControl, LinkButton)
End Sub
