  Environment Details:

  Reporting server migrated from 2005 to 2012.

  But we haven't migrated rdls and these reports are being viewed via reportviewer 8.0 version (2005).

  IIS 7.0 ( hosting environment has 8.0 & 11.0 dlls for report viewer)

  The reports are loading properly when limited values passed as parameter.

  When multiple parameters are passed (i.e. complete hierarchy tree selection), report is rendered as expected with 740 pages. But when user clicks on next page of report viewer control, we are getting "Invalid URI: URI is too long" error.

  As per suggestions on other blogs added settings to Report Server web.config. But it didn't worked for me.

  <add key="aspnet:IgnoreFormActionAttribute" value="true" />

  <add key="aspnet:MaxHttpCollectionKeys" value="100000" />
