I have an issue that I've spent hours trying to resolve without success. I am using the ReportViewer control in asp.net, LocalReport, no Reporting Services (but I'm not sure that matters). I think I should be able to do this but it may be a limitation of the control. Looking for any suggestions on this one...
On the .rdlc definition, I have 3 row groups:
mkt_name
->page_rows
---> details
The top level group, 'mkt_name', groups on a datatable's column called 'mkt_name'. **This is the field that I would like to have toggle on the report with +/- nodes.
The 2nd group, 'page_rows', has a group of : =Int((RowNumber("mkt_name")-1)/15)
Basically, I want to page every 15 rows. This is a must to prevent the screen from trying to paint 300 rows at a time. I have a page break set at the end of this group.
I am successfully paging at 15 rows but only because I have 'Visibility' of 'Show' for all groups. This isn't really what I want. Under 'Visibility', and the 'Display can be toggled by this report' section, I want to set the mkt_name group column for the toplevel group for either the 'page_rows' or 'details' group. So, the top-level mkt_name group will have a + sign, then when I click on that mkt_name, it expands the details *but only the 1st 15 rows*. Then, when the user clicks next page, the next 15 rows show up, etc.
What I have found is that when I toggle on mkt_name - on any of the sub groups, all rows come back. So, if there are 90 rows under 'mkt_name' of 'ABC', all 90 rows display, not the 1st 15. Only when I remove the toggling and set visibility to 'Show' for all groups does the paging at 15 work. Of course then I can't toggle the top level groups.
Hopefully this makes sense to someone. If so, any suggestions? Is this a limitation of the control. Any tips are appreciated! Thanks.
