Inserting a Page break into an SSRS report

I found an answer. Use a Rectangle at the bottom of each SubReport after all Tablixes and other rendering Objects. Then set its "PageBreak" property to "End". When the SubReport is finished with the Tablix and/or other data objects, the Rectangle forces a page break. Also, a cool feature, if the SubReport returns no rows of data, the page break is not rendered. Therefore, no extra page breaks

I tried the other answer here but my master report is driven by a dataset so didn't quite work out. This is how I got it to work for me:

1) I put the subreports into different rows on top of same size rectangles inside a Tablix with all the rows belonging to the same row group.

2) I then selected properties of the group, then pagebreak and checked the property pagebreak on between each instance of group.

Another solution would be to have the subreports placed inside the rectangles. I would imagine this would help you to better control and organize the layout of the report.
