Question : How to Reset Page Number in SQL Reporting Services for new grouping..

I have create a report using SQL Reporting Services which group by a field. In the report I use a
global field Global!PageNumber for the page number. Is there a way to reset the page number back to 1
if the field grouping change.

Just in case you don't understand. Let say, I have a customer sales report which group by customer.
Everytime when a new customer appear in the report I need the page number to reset back to
1. (i.e. customer A page 1 - 5, customer B page 1 - 5 ) instead of one continuous page number
from 1 to 10.

If you have the solution, please provide sample code and detail explaination.

FYI: I am using SQL Reporting Services standard edition which bundle together with the
SQL Server 2000 Standard Edition.

HELP!!!!!

Workaround #2 (Brian Welcker [MSFT])

Add this to the Code property of the report:

shared offset as integer

public function GetPN(reset as boolean, pagenumber as integer) as integer
if reset
   offset = pagenumber - 1
end if
return pagenumber - offset
end function

Use the function in the page number expression, basing the reset property on the presence of something that only appears on the first page of the group.
For example:

="Page " & Code.GetPN(ReportItems!tag.Value = "Tag",Globals!PageNumber)

Note: To make this work, the offset member variable must be declared as shared. This means the report cannot be run multiple times simultaneously, otherwise the separate runs will smash the shared member variable's value. In addition, failure to access the pages sequentially will have unexpected results (since the shared offset member variable will be set out of order). The only way to use this hack is to schedule runs of the report and save off the rendered results. Users cannot run the report live or even from snapshot history, since pagination occurs when the report is rendered, not when the snapshot is taken.
