Crystal Report Viewer print/export buttons not working in ASP.NET MVC app

问题

My MVC app uses the push model and the CR viewer for reporting. All works great in displaying the report in the viewer however the print/export buttons give the javascript error 'Object not supported by this action'. I am using VS 2008 and MVC. This happens in my dev environment. Any ideas?

The answer to this is so stupid its embarrassing - my popup blocker was causing this error. I did get another error or on th the deployed site however and that was a 404 not found on 'aspnet_client/System_Web/2_0_50727/CrystalReportWebFormViewer4/html/crystalexportdialog.htm'. I just created the folder and on the site and copied the contents of C:\Windows\Microsoft.NET\Framework\v2.0.50727\ASP.NETClientFiles\CrystalReportWebFormViewer4 to it and it fixed it.

Crystal Report uses javascript files to print and its own images that should be included on root directory of the website. I have solved this issue by creating folers on root directory of my website

aspnet_client/system_web/2_0_50727/

and copied the folder CrystalReportWebFormViewer4 from this path

C:\Windows\Microsoft.NET\Framework\v2.0.50727\ASP.NETClientFiles\CrystalReportWebFormViewer4

in 2_0_50727 folder i have created. Now print images and print/export buttons are displayed and also print and export functionality is working fine.

Thanks.

My problem was almost if not the same as yours. When I clicked export for print my report became clear. I updated my aspx page_load event to:

if (!isPostBack)
{
    Dataset allCompanies=datasetMethod(); ///Method Retaining a dataset
    ReportDocument oRpt=new ReportDocument();
    oRpt.SetDataSource(allCompanies);
    CrystalReportViewer1.ReportSource = oRpt;
    Session["Report"] = oRpt;
}
else
{
     CrystalReportViewer1.ReportSource = Session["Report"];
}

I was also faced with the same problem when I deployed my Website on IIS. Crystal Report didn't show me the print, next, previous etc. buttons, I then just created a folder inside wwwroot folder.

The complete path is:

C:\inetpub\wwwroot\aspnet_client\System_Web\2_0_50727`

I copied CrystalReportWebFormViewer4 from

C:\Windows\Microsoft.NET\Framework\v2.0.50727\ASP.NETClientFiles\CrystalReportWebFormViewer4

and pasted inside the 2_0_50727 folder.

Everything is now OK, but on the browser you have to allow the pop-up window to print your document.

I got the same problem when i removed the Default Web Site from IIS and added a new Website with different location.

If you are doing so, then we need to copy the aspnet_client folder from location C:\inetpub\wwwroot to the location where the newly configured Web site is mapped.
