How can I get the row count from a table that is in the detail, but show that total in a textbox in the footer?
The datasource on the table in the detail doesn't seem to be accessible from anywhere but the table.
The datasource on the report itself is different, containing some common items for display, but no data.
I've seen solutions that talk about adding a list or table to the header, but that doesn't seem to be allowed. The report designer does not allow that. "It is not allowed to add Table to pageHeaderSection1"
Is there a solution for this? Some way to make a report function that can be called from an expression? Or something like a field in the detail that is identified such that its value can be accessed in the footer?
Thanks
