I am experiencing the same issue as AngryBird.
setting the
C1ReportViewer1.Cache.Enabled = false;
C1ReportViewer1.Cache.ShareBetweenSessions = false; just DOES NOT WORK.
SANKALP AND THE REST OF THE TECHIES IN SUPPORT JUST DON’T UNDERSTAND THE ISSUE.
When 2 different website users attempt to print the same report, e.g. a Sales Order, generated with the same data, and this is the crucial point, AT THE SAME TIME, ON TWO DIFFERENT MACHINES BROWSING THE SAME WEBSITE, then as often as not user one will get user two’s order displayed and user two will get either user one’s order, or more frequently an AJAX Error ZERO.
One would expect the properties listed above to prevent behavior like this.
