title: Reportviewer inside user control issue
body: <p>i'm having a user control(ascx) that contains ReportViewer.
  I need to get total number of pages in the report (Ex. <code>RViewer.LocalReport.GetTotalPages()</code>). 
  I read that, the this value is available onle after <code>PreRender</code> event of Reportviewer.
  After this event, in aspx page (that contains this ascx); <code>Render</code> event, I'm getting the value as 0.</p>
  
  <p>I tried adding Reportviewer directly to another aspx page. Then in <code>Render</code> event of that aspx page, i got the right value for Total pages.</p>
  
  <p>Why I'm not getting with prior approach?</p>
