So you can see what I am seeing, the link below will download a sample project. It is the default VS2015 project with Telerik added, bootstrap.css modified, and default.aspx showing what I am talking about.
As it exists, it exports a PDF when the green button is pressed. If you swap the commented line in radclientexportmanager, it does not export. Only difference is the addition of PageBreakSelector=".test"
<%--<PdfSettings PaperSize="Letter" PageBreakSelector=".test" FileName="CODALite.pdf" Landscape="false"/>--%>
<PdfSettings PaperSize="Letter" FileName="CODALite.pdf" Landscape="false"/>
Project link.
