Grid lines on SSRS report

I've scoured the web trying to find how to turn on gridlines (cell borders for a report) using ReportViewer in Visual Studio 2012. The only information I really found was to click the column tab and then set the BorderStyle to Solid. Then click the row tab and do the same. I did this but it didn't have any effect when the report was rendered. Can someone please tell me how to turn on the gridlines/cell borders so that they show when the report is rendered and also when printed?
Thanks
