Thanks Randy

So I've just added top and bottom buttons to
my viewtable toolbar.

Disappointingly, VT suffers the same behaviour
as FSV when I goto lastrow. They scroll slowly.
This contrasts very  unfavourably with FSBrowse
which immediately gives the last obs when I press
Cntl+PgDn
Now, if only that speed was available for the
VT command bottom !!
I see no reason for the slow pace of VT (bottom)
I had hoped the handling of
   goto row-num -4
might speed things up, but ... I can't tell !


Kind Regards
Peter Crawford

Nachrichtentext:

Peter,

The reserved numbers seem to work as documented, but the functionality has
been available by using the formViewer's default popup menu or the navigator
buttons.

The documentation for the tableViewer's _gotoRow method, doesn't specify if
the row parameter is relative or absolute.  I tried a quick test which seems
to indicate that it is relative, but the reserved numbers available for the
formViewer's _goToRowNumber method do not work for the tableViewer's
_goToRow method.  The tableViewer, as implemented in Viewtable, does provide
the TOP and BOTTOM commands as well as the First Row and Last Row popup menu
items.

I see a new/updated usage note that may contribute to
at least one wish-list item for ViewTable
product = AF
   008095 Reserved numbers that perform routine actions for the
_gotoRowNumber
        method
   SN     http://www.sas.com/service/techsup/unotes/SN/008/008095.html

This contains some "magic row numbers"

Information on the reserved numbers that perform routine actions for the
   _gotoRowNumber method of the Form Viewer Control were left out of the
   documentation. Details on these reserved numbers for the row-num
   argument are provided below.

   row-num  N   specifies the row to display. Row-num is a relative row
              number. Reserved numbers that perform routine actions are

              -1  go to the first row
              -2  go to the previous row
              -3  go to the next row
              -4  go to the last row.
With row-num -4
we might get a fast route to the last row=end of table.

Can anyone confirm this ?

Regards
Peter Crawford
