I am creating a new report in SQL Server Reporting Services 2008 R2. When I click on the "Preview" tab an error message is displayed reading:
The report preview failed because the report could not be built. Read the errors, warnings, and messages in the Error List window for specific build failures.
However, there are no errors, warnings, nor messages in the Error List window. Furthermore, the Build Output shows:
Build complete -- 0 errors, 0 warnings
========== Build: 1 succeeded or up-to-date, 0 failed, 0 skipped ==========
I have checked to make sure the report in the build directory is not read only. I have closed/restarted Visual Studio. I have closed/reopened the report file.
A special file in my [Project Folder]/bin/Debug folder, build.obj, has become marked as Read-only. When I remove the read-only flag on this file, the report is now able to be previewed.
