I have sql query which shows me data in RDLC report. Query is not important for this purpose, so let's just say that I have table with name, city, country, company, phone number. I want to display list of all data, sort by country, but first only show country that begins with "A" then I want page break and on new page to "print" country with B and so on. There must be a proper way to do this but I don't know it.
To page break your report based on the first letter of the field only, first add group by your Country field, then click on Expression button (fx button) in group property:
and edit your grouping expression to be
=Left(Fields!Country.Value, 1)
And then set your page break in "Page Break" tab:
