I have an SSRS report with 2 sub-reports that had been working fine. Recently I added some additional table sections to the report and I started seeing and issue when the report was displayed in the interactive viewer. The data is fine but the formatting on the last 2 table sections does not appear in the veiwer. The formatting actually stops working half way through the next to last report. However, when I print the report (or export to a PDF), all of the formatting is there and the report prints fine. I have tried splitting the report into more sub reports, running with different data and it still does not display correctly in the interactive viewer. The report and subreports do have a lot of formatting and table sections and I am wondering if the rdl files are too big to store in memory or if they even do get stored in memory. The rdl file sizes are 61 KB for the main report and 2612 KB and 2608 BK respectively for the sub-reports. Is there a size limitation on the rdl files? Any ideas?
If you split the report into its component parts does it display ok? If as you say you have recently added some new sections/Sub reports to it if you remove them does it look ok again.
You have probably got some strange overlapping happening, in the report designer when the report complies check the warning tag to see if it gives you any clues
I have found a work around for my problem. If I render my report directly to a PDF, then the report will not display in the interactive viewer, but only as a PDF which displays correctly. This is done by adding "&rs:Format=PDF" to my URL when I call it from my C# program that allows the user to input the parameters. Then the user can print the report and never see the missing formatting in the interactive viewer. This works for my, however, I would still like to know if there is another answer that allows it to view correctly in the interactive viewer or if I have surpassed some memory limitations.
