I need to display a Textbox in the body of the report, but it has to be on a separate last page. It is actually a Word file that needs to be shown in each report, but seeing as how the only way to accomplish this is to put the file to the Report Server and then access it with a link, I decided to copy the contents of the file to a Textbox.
This and this question on SE are similar, however it is not exactly what I need.
You can achieve this by adding items with appropriate page breaks to the report.
Say I have a simple report with a table and a textbox:
The end result looks about what you'd expect:
However, we can force the textbox onto a new page by embedding it in a Rectangle and setting the Rectangle to always be preceded by a page break:
Now the report displays the textbox on the last page:
Tables themselves can also have page breaks, but since it's just text with no dataset it makes sense to me to use a Rectangle here.
