Tworzę oprogramowanie, które pomoże mi w pracy. Odczytuje dwa pliki excel (xlsx) i otrzymuje się z nich pewne informacje. Następnie umieszcza informacje w jeden z dwóch widoków datagrid lub w obu reprezentacji datagrid.
Następnie mam pokój, który trzeba pokazać w przypadku drukowania obrazów datagrid. W podglądzie wydruku wszystko jest dokładnie tak, jak ja chcę, ale w przypadku drukowania na papierze usuwa (lub nie pamięta) wszystko, co dotyczy pierwszej prezentacji danych i wszystkim, co piszę z nim, i zaczynam od 2-go prezentacji danych.
Oto, jak jest to pokazane w podglądzie:
ale gdy wpisuję to na papierze, mam oto takie
Dlaczego pierwszy datagridview wyszedł na papierze, ale jeśli wydrukuję ci go w formacie PDF z Microsoft print to PDF, dostanę PDF, który ma dokładnie taki sam podgląd.
Problem występuje tylko w przypadku drukowania na papierze.
