COLUMN HEADINGS DO NOT REPEAT IN SSRS 2008
I've just stumbled upon an odd issue with the Tablix control in SSRS 2008. I deployed a report on a server a few weeks ago and it is now reporting on enough data to make it span multiple pages. I wanted the column headings to appear on all pages, not just the first. However, when I set the RepeatColumnHeaders property on the Tablix to be true, the headings still did not appear on the next page. After a bit of playing around I enabled Advanced Mode in the Grouping Pane, and had a look at the properties for the top (Static) group in Row Groups. Under Other, there is a property called RepeatOnNewPage. Setting this to True made the column headers appear as required. OK, so that's fine, but I can't help but think that this a a bug in SSRS 2008, and should be fixed by MS. Looking through the RDL file itself, I can't find anything that would cause the RepeatColumnHeaders property not to behave as expected.
The "Header should remain visible while scrolling" option does not appear to work either; I haven't yet found a workaround for this.
