We recently upgraded a WinForms application project from Visual Studio 2008 to Visual Studio 2010. As such, we also upgraded from the ReportViewer 9 control to the ReportViewer 10 control. However, we found that the version 10 control has some display issues that the version 9 control does not.
Specifically, the version 10 control does not appear to handle automatic row sizing properly, causing CanGrow cells to appear as blank cells in the display, even though the row height appears tall enough to show the report text. (Effectively, the entire report can appear blank with some text visible in few places.) Print Layout view does show all of the data properly, however. Reverting back to the version 9 control (still within VS 2010) resolves the problem, but then we lose the resizable multi-select drop downs offered by version 10, and, of course, the version 9 control cannot be opened in the form designer in VS 2010.
Is there a patch available to correct this issue? Is there a configuration setting available to work around the issue? We don't want to have to go into our many, many reports and manually resize each row to a minimum height that does not produce the problem.
Here's a weird inconsistency with this problem to add some confusion to the matter: The problem does not appear to occur when I test this against a report server running locally on my Windows 7 laptop (SQL Server 2008 R2 Developer Edition, SP1), but does occur when I test this against various remote report servers (Windows Server 2008 R2, some with SQL Server 2008 R2 Developer Edition, SP1, and some with SQL Server 2008 Standard [not R2]).
