Paging using Web Services

We are developing a Web Application for which we have written a class to
render reports that consumes web services provided by Reporting Services.
We invoke "Render" method of web service for displaying report in aspx page.
Paging is achieved using "Section" config of HTMLDeviceInfo passed to render
method.
This approach is working fine for First Page, Previous Page and Next Page
buttons. However we are not able to implement code for Last Page Button
because we are unable to retrieve details regarding total number of pages
through code.
Documentation states that if a value greater than last page index is passed
to "Section" config then Web Service would render last page. This behavior is
causing our code to crash.
Any idea how to overcome this problem.
Thanks in advance.I've described my approach a few months ago.

Pagination Issue when Rending to PDF

I am having a pagination issue with a report when I render to PDF. The
report is a patient form that is based on a single record that is returned
from a stored procedure. Most of the records are output fine, but some
records are not paginating properly and leave 3/4 page of blank space. The
field that follows on the next page is short and should definitely fit on
that page. The report renders fine in HTML, but the requirement is a PDF
format.
The body of the report is contained in a table. Each field of the report is
contained in its own row. If the field is blank, the entire row is hidden so
that only populated data is output in the report.
In troubleshooting this, I have removed the logic that hides the rows, but
the pagination is still not correct.
I have also made sure that the data is clean and doesn't have whitespace.
Any suggestions as to how to fix this problem?

You will want to check the width of the report. Normally, if it is
wider than 6.5" in design view, it will wrap once exported to PDF.
Also, if you are using a table control, you will want to put it into a
rectangle control, this should shrink the extra space. Hope this
helps.

Sr. Software Consultant|||Thanks for the quick reply. The report is slightly wider than 6.5" in design
mode to incorporate the header (which renders fine). The fields before and
after the blank space are very short (like 1 word and a label).
I did try putting the table in a table control, but that didn't do anything.|||On Dec 18, 9:43 pm, JC <J...@.discussions.microsoft.com> wrote:

You're welcome. Did you mean you put it into a table control or a
rectangle control?
Enrique Martinez
Sr. Software Consultant|||Sorry. I meant that I put the table control inside the rectangle control. I
just removed all code that controls the visibility property for each row, and
the pagination problem went away.
The problem is that the customer only wants rows of the table to appear that
have data. Here's the code on the visiblity property of the tablerow:
=iif(Fields!FirstSignature.Value = string.empty, True, False)
It does work as it is supposed to, but it seems that the space is still
being allocated for the row.
BTW, it was initially written in VS 2003, but I have tried with VS 2005 with
the same results.|||On Dec 18, 11:05 pm, JC <J...@.discussions.microsoft.com> wrote:

You might try =IIF(Fields!FirstSignature.Value = Nothing, True, False)
or =IIF(IsNothing(Fields!FirstSignature.Value), True, False)
Either should do what you want. Make sure you set the property for
the row and not the individual cells/textboxes.|||Thanks, Toolman.
I will try that too. Is using the table + row format to hide empty fields
the best practice to accomplish this? I was also going to try to set the
height to 0 if it was going to be hidden. It just seems that SSRS is taking
the empty rows into consideration when making the pagination decision.|||On Dec 19, 2:32 pm, JC <J...@.discussions.microsoft.com> wrote:

I believe that it is. If for no other reason than the convenience of
not having to enter the expression for each textbox/cell. Also, my
experience has been that using a table rather than a collection of
boxes just works better in general. I know that trying to hide the
entire row by hiding all the cells doesn't seem to close up the white
space.
