Reports not loading after upgrading from version 11 to 15

    Hello,
    We use ActiveReports extensively on our website and recently upgraded to version 15 from 11. After the upgrade neither the designer in Visual Studio nor the web view report at run time would work. When I try to open the report designer in visual studio the following happens


    When I try to run the report the following happens.


    I have tried to troubleshoot this by removing/adding references, by installing the packages using both NuGet and installation file downloaded from Grapecity website. Tried on 2 different development machines with same results. Tried adding/removing/upgrading references in web.config also without success.

    We have used the reports upgrade tool previously for earlier versions without any issue. But the upgrade from 11 to 15 is very frustrating. Please let me know how to proceed to rectify the design and run time issues.

    Thank you

    Hello,

    >>When I try to open the report designer in visual studio the following happens
    Can you try after adding the "GrapeCity.ActiveReport.Serializer" manually in your project.

    >>When I try to run the report the following happens.
    Can you share the stripped down application so that I can look into the issue at my end hand, Also, you can try after removing the handler in Web.Config as you don't need handlers in AR15.

    >>But the upgrade from 11 to 15 is very frustrating. Please let me know how to proceed to rectify the design and run time issues.
    Actually, there is huge change between AR11 and AR15 to support the .Net Core. That's why you are facing this issue. We are moved to the NuGet system instead of putting dll in the GAC. Also, the backend and frontend of WebViewer is completely changed in the AR15.

    Thanks,

    Thank you for the reply. After adding GrapeCity.ActiveReport.Serializer, the report designer loaded fine.

    Could you please send me a sample webviewer code for AR15.

    Thank you

    Thank you. Here is the current code that I have(stripped down version)

    Report file designed with designer
    public class ARTextReport : GrapeCity.ActiveReports.SectionReport {
    public ARTextReport() {
    InitializeComponent();
    }
    }

    aspx file declaration
    <ActiveReportsWeb:WebViewer ID="ARWebViewer" runat="server" Height="1100px" Width="850px" ViewerType="HtmlViewer" />

    aspx.cs file code
    ARTextReport report = new ARTextReport();
    report = new ARTextReport();
    report.PhotoReport = deficiencyReport;//This is the data source
    report.Run();
    ARWebViewer.Report = report;

    I am still getting the attached error while loading the reports...used to work perfectly in version 11!!

    Thank you

    Hello,

    I have created the sample using the same code but unable to reproduce the issue at our end. Please refer to the attached sample.

    Could you please make sure that there is no handler in the Web.Config file as there is no need of it in AR15. You can match the Web.Config of your sample with the attached one to remove the unwanted entry of the AR in the file.

    If problem still replicate, please share the stripped down sample.

    Thanks,

    Hello,
    After adding the following code to Global.asax file and the "Report missing" error was solved,
            void Application_Start(object sender, EventArgs e) {
    this.UseReporting(settings => {
    //settings.UseFileStore(new DirectoryInfo("Specify the path to the directory with reports"));
    settings.StoreTemporaryFilesOnDisk(new DirectoryInfo("D:\\Websites\\Temp"));
    settings.UseCompression = true;
    });
    }


    However all I see are blank pages, no matter which report I try to run. I do see temporary folder and files created in the Temp folder mentioned above.

    Please let me know what else I can do to get this resolved.

    Thank you

    The project is very big and files are dependent on too many other libraries to replicate the issue on a different environment. I am not sure how to share the sample. I can see the files being created inside the temp folder(like _page1.html, _page2.html etc.), but the browser displays just blank pages. Not sure what I am missing..

    Thank you

    Hello,

    Are you able to replicate the issue with sample attached here:

    Also, you can try the UseCustomStore as mentioned in the following link:

    I have created a new sample asp.net web project and added one of our simplest reports. Please get the zipped solution from below

    ARTermsReport.cs is the section report and Terms.aspx has the webviewer.

    Please let me know the fix for this problem.

    Thank you

    Thank you for the reply. I got the report working with the modified files. However I have couple of questions
    1. I can't find where the webviewer to report association is made. Previous code has ARWebViewer.Report = report for this to happen. We have like 15 different types of reports with custom data.
    2. How do I bind our custom data source objects to the reports!! I surely cannot do that in Global.asax file. Currently we bind them using the DataSource property in the report aspx file.

    Thank you

    Hello,

    In your application, you have set the "AutoEventWireup" attribute of "Terms.aspx" page to 'False'. That's why "Page_Load". event never fire and Viewer show the error. Please refer to the following link:
    https://www.c-sharpcorner.com/UploadFile/puranindia/what-is-the-autoeventwireup-attribute-in-Asp-Net/
    If you set the "AutoEventWireup" attribute to true in your original application, it will work as expected.

    Thanks,

    Thank you Mohit. I set the AutoEventWireup to true and it did not change anything.

    It is working fine at my end. Please refer to the attached gif. Have you tried with the sample which you shared with me.

    Yes, the sample project works fine even without AutoEventWireup set to false. But when I use the same code in my actual project it still displays blank pages!!

    I read in another article that AR WebViewer only works in Integrated mode of the pool. Is this accurate? Our website uses classic mode and we can't switch to integrated mode easily.

    Thank you

    Hello,

    >> Is this accurate?
    Yes, you cannot use AR WebViewer in the ClassicMode. Actually, AR uses OWIN internally and Owin does not support classic mode. Please refer to the following link:
    https://docs.microsoft.com/en-us/aspnet/aspnet/overview/owin-and-katana/owin-middleware-in-the-iis-integrated-pipeline

    However, request to please confirm are you comfortable to view the report in PDF instead of the in Viewer.

    Had I known about the integrated mode beforehand, would've saved me almost a month's worth of trouble.

    So what other ways can I use instead of WebViewer? I am looking to display reports in the browser like we currently have using WebViewer.

    Thank you

    Can you export the report in PDF and display the in the Web Application.

    Again, we are very sorry for all the trouble.

    Yes, we already provide the PDF export option to our clients. But our clients use the webviewer's built in report navigation and search options regularly, so taking out webviewer is not an option for us. We either stick with version 11 or find another product that does the same.

    Thank you

    Hello,

    We are very sorry for the inconvenience caused to you. However, as per the new architect of the new WebViewer, you can't use the WebViewer in classicMode.

    Hello, I have finally migrated our pool to integrated mode and all the reports started working fine. However the photos inside the reports are just blanks.
    Please see the attached screenshot, the blank square used to display an image a byte array loaded from the database.

    Thank you

    Nevermind, adding the folloiwing line to web.config handlers sorted the issue

    <add name="nostaticfile" path="api/reporting/*" verb="GET" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
