    A client site is running our ASP.NET 3.5 web-application which includes the Report Viewer control for reporting. They have recently upgraded to IE11, which must be run in native/standards mode.

    In order to get the print function of the Report Viewer control working, we have upgraded the Report Viewer control to the 2012 version and have applied patches / updates as per instructions here:

    Part of these instructions are to remove any browser files, however we are currently using the RadHiddenFieldPageStateCompression utility to compress viewstate (specified as per Telerik documentation in the Default.browser file).

    If we remove the Default.browser file, the Report Viewer print function operates correctly, but viewstate compression no longer works. Adding the Default.browser file back in, hides the print button on the Report Viewer control.

    Is there any way that we can retain viewstate compression and use the SSRS 2012 Report Viewer print function?

    In this case I would suggest you to use the Dynamic IIS compression. If you configure dynamic content compression, your viewstate, part of the HTML in the form of a hidden input element, will be compressed by IIS.
    Give this a try and see if it helps.
