Hello. I need to create report with 'Group By' parameter on request page. When User select 'No' - group in RDLC layout will be grouping by No. If User select location code - by location.
How can I do it? How can I pass the value to layout as report parameter? (when I create new column with Group By variable - this variable is passed just like normal Field.Value and i can't use this to create grouping expression)
