Reports REST server not working in Azure Application Service

Hi all - we have a website which uses Telerik Reporting, setup as a REST webservice - we have a backend api which makes calls to the Telerik service.

We have 3 separate environments - DEV, STAGING and PROD, of which only PROD is giving us problems.

Thought it might be a firewall issue, but now thinking something is interfering with the REST service - after tracing a few calls, the client id is created and given back, but often when we send it to get a report, we get an error that the client is is "not found" and "expired".

I've also seen it get PAST this part, go ahead and generate the report, then give back the ID, but when we make the call to fetch the report document, we get a "gone" error.

It seems like a session is started when the client 1st gets the client ID, but does not stay alive, or is being killed, before we can do anything.,

I HAVE ALREADY SET ClientSessionTimeout - tried setting it to 16 minutes, but the call to api/Reports/clients/sessionTimeout ALWAYS return 960 - ???

I'm thinking it's maybe some Azure Application Service setting, but I'm not the one who would check, I'm just a programmer, hoping to have some ideas to pass along to the Azure team here.

Thanks!

Blazor Report failes when report runs to more than 10 or so pages

I report that crashes if there are more than 10 or so pages. I have simnpified this report so it has no formatting, no grouping and only one field of data. I have made this report as simple as I can.

When I run the report I get the error below.

{"message":"","exceptionMessage":"One or more erro…ype":"DocumentRenderException","stackTrace":null}', _error: '', _responseJSON

If I run the same report but filtered for fewer pages, it works fine.

[Solved] showing combobox as editor type instead of listbox in report viewer

I'm trying to show comboboxes instead of list using following lines of code but it is not working. It keeps showing me the listbox only.
My version is 18.1.24.514 and given code is part of angular application in my typescript file.

this.viewer = $('#reportViewer')
      .telerik_ReportViewer({
        serviceUrl: `${environment.apiUrl}/reportdesigner/`,
        reportSource: {
          report: `${reportName}`,
          parameters: {
            editors: {
              singleSelect: 'COMBO_BOX',
              multiSelect: 'COMBO_BOX',
            },
          },
        },
        parametersAreaVisible: true,
        parametersAreaPosition: 'TOP',
      })
      .data('telerik_ReportViewer');

Any help on this?

hoe to configure the Authentication Token in Reports controller

Hello,

I am using the Telerik Angular Report Viewer and Reporting REST service to configure Telerik Reporting. However, I am unable to obtain the authorization token needed to set the connection string. I have implemented the Telerik custom report source resolver in my application. After reading a few articles, I learned that the authorizationToken can be set in the HTML file. However, I am unsure how to apply this token in my report controller or within my custom source resolver.

Telerik angular viewer :

<div class="modal fade show full-width" tabindex="-1" role="dialog" style="display:block">
            <div class="viewer-container">
                <tr-viewer #viewer1
                                     [containerStyle]="viewerContainerStyle"
                                     [serviceUrl]="msServiceURL"
                                     [reportSource]="mobjReportSrc"
                                     [viewMode]="'CONTINUOUS_SCROLL'"
                                     [scaleMode]="'FIT_PAGE_WIDTH'"
                                     [scale]="1.0"
                                     [ready]="ready"
                                     [viewerToolTipOpening]="viewerToolTipOpening"
                                     [enableAccessibility]="false"
                                     [keepClientSideReportInstance] = "true" 
                                     [authenticationToken] ="strToken"> </tr-viewer>
            </div>
</div>
Report controller - 
[Route("api/BME/[Controller]")]
[ApiController]
public class ReportsController : ReportsControllerBase
{
    public int ClientSessionTimeout { get; set; }
    public ReportsController(IReportServiceConfiguration reportServiceConfiguration, IConnectionFactory connectionFactory)
        : base(reportServiceConfiguration)
    {

    }
 
Thank You,
Pragati

Search not highlighting found text in BlazorNative viewer

I am upgrading my Blazor application to .Net 9 and changing the report viewer from the older Blazor viewer to the new Blazor Native viewer and I have found that when I use the search to find text within a report that the text when found is not highlighted as it was in the previous version. I've followed the instructions for configuring the viewer and everything else seems to be working correctly. I'm not receiving any error messages so I don't know if this is just a missing feature not implemented in the newer Native viewer.
