HI,
I have a problem with Telerik Web Report Designer (17.0.23.515) as explained in the documentation I proceeded to create api service controller and the view to host the application but when I run it I get an error poup with the following message :

Could not retrieve information for folder . Warning, model validation error detected!

Do you have any suggestions/info to solve the problem?

P.S: I've verified that the app can read and write to the report folder.

Thank You

Good afternoon, 

I'm trying to generate a barcode with GS and RS characters inside a barcode with no success (those are mandatory for GTL labels in VDA standard).

I've been trying to do Char(29), Chr(29), ChrW(29), (char)29, Convert.ToChar(29), ... but nothing worked me.

Best regards

Hello,

I am getting the following error when trying to print a report from my website:

But when in my local machine, it displays correctly. The database is the same, no changes between then.

My report viewer was working without issue for some time until caching with DistributedSqlServerCache was implemented. It is configured as follows.

services.TryAddSingleton<IReportServiceConfiguration>(configuration =>
    new ReportServiceConfiguration {
        HostAppId = "Reports",
        ReportingEngineConfiguration = new ConfigurationBuilder().AddJsonFile(Path.Combine(configuration.GetService<IWebHostEnvironment>().ContentRootPath, "appsettings.json"), true).Build(),
        ReportSourceResolver = new UriReportSourceResolver(Path.Combine(configuration.GetService<IWebHostEnvironment>().ContentRootPath, "App_Data")).AddFallbackResolver(new TypeReportSourceResolver()),
        Storage = new MsSqlServerStorage("connection-string")
    }
);

public class ReportsController : ReportsControllerBase {
    public ReportsController(IReportServiceConfiguration reportServiceConfiguration) : base(reportServiceConfiguration) {
        reportServiceConfiguration.Storage.AcquireLock(string.Format("Lock-{0}", new Random().Next()));
    }
}

Note that the AcquireLock() method mentioned above was added in response to this comment from Telerik:

The interface also exposes a method called AcquireLock which is used from the service to enforce serialized access to all stored resources from each thread of the application and between the instances of the application in case of multi-instance environment (i.e., Web Farm)

Which I suspect may apply here, but unfortunately I can only hazard guess in light of its appalling lack of documentation.

A typical error message reported by the viewer is:

Error creating report document (Report = 'XXXXX, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'; Format = 'HTML5'). An error has occurred. Object reference not set to an instance of an object.

function registerDocumentAsync(format, deviceInfo, useCache, baseDocumentId, actionId) {
    throwIfNotInitialized();
    throwIfNoReportInstance();

    return client.createReportDocument(clientId, reportInstanceId, format, deviceInfo, useCache, baseDocumentId, actionId).catch(function(xhrErrorData) {
        handleRequestError(xhrErrorData, utils.stringFormat(sr.errorCreatingReportDocument, [ utils.escapeHtml(report), utils.escapeHtml(format) ]));
    });
}

to this:

function registerDocumentAsync(format, deviceInfo, useCache, baseDocumentId, actionId) {
    throwIfNotInitialized();
    throwIfNoReportInstance();

    return client.createReportDocument(clientId, reportInstanceId, format, deviceInfo, useCache, baseDocumentId, actionId).catch(function () {
        console.log("Failed to create report document. A retry has been attempted.");

        return client.createReportDocument(clientId, reportInstanceId, format, deviceInfo, useCache, baseDocumentId, actionId).catch(function (xhrErrorData) {
            handleRequestError(xhrErrorData, utils.stringFormat(sr.errorCreatingReportDocument, [utils.escapeHtml(report), utils.escapeHtml(format)]));
        });
    });
}

Hello,
