Consider a scenario where we want to show the old style "Add new item" at the bottom of the XSLT List View Webpart instead at the top as in SharePoint 2013. This can be done easily by setting "Server Render" property of the XSLT list view webpart. This is how list view webpart appears in SP 2013.
Edit the page containing the webpart and click on Edit Web Part. Open Miscellaneous section and check Server Render property and save the web part.
Stop editing the page and notice the result.
Same result can be achieved in code by setting ServerRender property of the XSLT list view webpart to true.
