title: How to dynamically change the number of columns in an SSRS body
body: <p>In SQL Server Reporting Services (SSRS), the number of columns on a page for a report is set in the Report Properties (this is not the same as the number of field columns which vary with the data).<br>
  By default this is set one, but it could be two or more, flowing down then across.  </p>
  
  <p>I want to be able to set this dynamically, depending on the type of printer I'm using (label roll or sheet).  However, SSRS does not allow you to enter an expression for this value.  Does anyone have a way of doing this via code?  </p>
