Using Report Builder 3.0 connected to SQL 2012.
There is a border around the body (except for the bottom) and the page footer(except for the top). The body contains a tablix. I added a couple of rows to the tablix and did a bit of merging and now the left and top borders of the body have dissapeared.
I am sure I can go back to the original and find a way to avoid this issue. However, I would prefer to have a good understanding of what controls the visibility of the border. The border visibility should not be subject to what happens inside a tablix unless the left side of the tablix covers the left edge of the reports and even then the report border should appear in front of the tablix border.
Are there some general rules or tips to avoid this result?
