Hello sir/madam,

I have an issue with reporting generator XLSX file:

- Version Telerik Reporting 18.2.24.806 (Q2-2024)

- version Telerik.Reporting.OpenXmlRendering 18.2

Please any help,

I finally figured out that I can transfer any Telerik design in Clipboard:

            IDataObject dataObject = Clipboard.GetDataObject();
            if (dataObject.GetDataPresent("CF_TELERIK_REPORTING_NET20"))
            {
                var services = new ServiceCollection();
                ServiceProvider provider = services.BuildServiceProvider();
                //IServiceProvider provider = new DefaultServiceProviderFactory().CreateServiceProvider(services);
                byte[] data = (byte[])dataObject.GetData("CF_TELERIK_REPORTING_NET20");
                var service = new CodeDomComponentSerializationService(provider);
                using (var stream = new MemoryStream(data))
                using (SerializationStore store = service.LoadStore(stream))
                {
                    //using var store = (CodeDomSerializationStore)service.LoadStore(stream);
                    var components = service.Deserialize(store);
                    store.GetType();
                }
            }

Hello and sorry if it has been questionned before but I couldn't get my answer on the previous topics.

For short story : I have arrays in SubReports that I show in my main report. These are big arrays and therefore they spread between pages which is not a problem but between the pages with the parts of the array there is always a blank page.

Now for more informations:

- Both my main report and my subReports are A4 formatted with 0 margins and 21cm width.

- In my DetailSection I have List (21cm width) that contains a List (21cm width) that contains my SubReportItem (21 cm width)

- I have many arrays but the 2 having a problem are the big ones that spread to multiple pages.

- All the "KeepTogether" properties are set to false wherever that was possible

- In the subreports, I created Tables and not CrossTabs

- I tried to generate a report only using what's supposed to be the subReport and they spread ok between the pages without blanks which makes me think the problem comes from the fact that they are SubReports ?

I have a report that I'm viewing in a WPF app.  The report looks perfect on-screen and when I export to PDF.  However, when I export to "Word Document", there are a few fields that simply don't show up in the Word document.  There is also, in the page footer, a horizontal line that comes out as just a partial line, and footer text that doesn't appear at all.

Are there any pointers or suggestions to get these working?

Hello,

Im using version Telerik Reporting 18.2.24.806 (Q2-2024).

Template file is .trdx

Below is my code:

var reportProcessor = new ReportProcessor();
var deviceInfo = new Hashtable();
deviceInfo.Add("ComplianceLevel", "PDF/A-3b");
 deviceInfo.Add("FontEmbedding", "Full");

var result = reportProcessor.RenderReport("pdf", reportSource, deviceInfo);

after run happen error: 

We have a longer text in our report, which also contains this string "ISO 5834-1:2019", which we don't want to break into a new line.

Reporting Services seem to have the possibility to use the chr()-function to inject 'unbreakable' characters, but this doesn't seem to work in Telerik Reports.

How can we make sure, that there is no line break possible for the given string? 
(Line break in the rest of the text is ok, though.)

Hi, I recently upgraded from 19.1.25.716 to 19.0.25.313. I updated my stand along designer, regenerated reports, and updated my dlls and js files. I was recieving telerikViewer does not exist errors, so I referenced telerikReportViewer-19.1.25.716.min.js in addition to telerikReportViewer.kendo-19.1.25.716.min.js and the error went away.

When I view the report, the report is blank except for a splitbar. However, if I view the DOM in dev tools, the report is there with data. If I remove the class "trv-pages-pane" from one of the div elements, the report appears (though the parameter input fields are still hidden).

Any idea as to what's going on?

$("#reportViewer7")
                .telerik_ReportViewer({
                    serviceUrl: "http://example.com:7655/api/reports/",
                    authenticationToken: "xxxx", 
                    reportSource: {
                        report: "7_0"
                    }
                });

 Users are getting a white screen when opening reports. It is intermittent. Once it happens for one user it happens for others but not all

telerik report version is ; 16.1.22.622

We are using Telerik report server version 2025Q2 with a Blazor UI, since we have upgraded when you select a parameter in the parameter list it does not shade it or do anything to indicate it has been selected. The report does run so it's really selecting the parameters but it does not reflect that. Is there a fix for this?

Thanks,

Toya

I need to get the values of some fields shown on a report in a VB.NET / Winforms app, and I've used the code from here;

https://docs.telerik.com/reporting/embedding-reports/program-the-report-definition/access-report-items-programmatically

However, I'm experiencing a crash at the first step of getting the InstanceReportSource with a cast exception as per the title.

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    Dim instanceReportSource As InstanceReportSource =
                DirectCast(Me.TKReportViewer.ReportSource, InstanceReportSource) <========= Invalid Cast here
    Dim report As Telerik.Reporting.Report =
                DirectCast(instanceReportSource.ReportDocument, Telerik.Reporting.Report)

    Dim txt As Telerik.Reporting.TextBox =
                TryCast(report.Items.Find("quoteReferenceNumber", True)(0), Telerik.Reporting.TextBox)

End Sub

I can't find any other questions / answers on this - anyone have an idea what might be wrong?
