    Report Viewer Export to Excel hangs on opening file


    Hi,

    I am using ASP .NET ReportViewer to display my reports. All reports are functioning successfully.

    However, some users, are unable to export certain reports to Excel. After the user selects the Export link and after choosing to Save or Open, the window just hangs and does not open or save the file.

    What I have tried:
    Having the user increase their IE cache.
    Comparing versions of Excel: same version, not the issue.

    I can't find any common association between the reports that work and the ones that do not based on report size or user's machine configurations. The only time I have been able to solve this for a particular user is by having the user manually shut down all unnecessary applications to reduce CPU usage. This worked; however, I had the user reopen all their applications to increase CPU usage, and the reports still worked.

    I'm not certain if this is a Windows issue (maybe something dealing with the Registry) or a .NET issue with the code behind how it generates the Excel code.

    Any help is greatly appreciated.

    Thanks,
    Fani

    RE: Report Viewer Export to Excel hangs on opening file


    Hello,

    I am getting the exact same issue with the ASP.NET ReportViewer. The user selects open or save and it just hangs there. Only some users say they have this issue, and even then the problem is intermittent for some and more consistent for others. I'm not really sure where to start looking.

    Any help would be appreciated.

    Thanks,
    Steve
