We are trying to create a user interface with UI for Blazor that allows users to view and choose parameter values for their reports without having to go into the report viewer. However, the complexity of some of the expressions used for things like display value, available value filtering, and default values pose a challenge to evaluating those parameters ourselves. Is there a way to programmatically evaluate those parameters for the above using the telerik reporting library so that we can display them in our UI?

We are using the Telerik.Reporting.Report object to get the parameter data, and have also tried instantiating a InstanceReportSource for the object as well but both have only given the expression for display value/available values/default values rather than the evaluated values.

Hi anyone,

Has anyone tried to append a pdf page when a report is generated or printed, is there any solution to this issue?

I have project in WinUI3 and I want to append a pre-existing pdf to the report, not in the footer but at the last page, is the there a way of achieving this without 3rd party libraries?

Hi

Using telerik report in react, showing report in Report Viewer and all fine.

Now need to get the PDF (inline, not download) of this report from Report Viewer programmatically. (Not in backend). Is there is a way to get the PDF.

I can download PDF using viewer.current.commands.export.exec("PDF"); but i need to get pdf contents. (need to upload to azure blob)

Also when we export PDF manually, ReportViewer calls the CreateDocument endpoint  [HttpPost("clients/{clientID}/instances/{instanceID}/documents")] 

to get the document id. and then uses clientid, instanceid and documentid to get pdf.

In react how can we get the client id and instanceid from Report Viewer.

Thanks

Hello all!

I have what feels like a very simple example of using 2 cascading parameters in a report. The first parameter is loaded with no issue but come time for the second, I get a "Response status code does not indicate success: 400 (Bad Request)".

I notice in the REST service call that it is passing hasChildParameters as false. I don't see an option to set that as true.

I've found when I run the download in designer with matching values that are expected in the parameter it retrieves without issue. This is purely a runtime issue.

Here are a few screenshots of what I have setup. Any advice is appreciated.

hi,

    I want to display a report book with the .trbp suffix in the ReportViewer component of Telerik UI For Blazor, but when I assign the ReportSource, it prompts that it cannot be converted from Telerik.Reporting.UriReportSource to Telerik.ReportViewer.Blazor.ReportSourceOptions. Is there any specific case reference?

<ReportViewer ViewerId="rv1"
              ServiceUrl="API/Reports"
              ReportSource="@BookReportSource"
              Parameters="@(new ParametersOptions { Editors = new EditorsOptions { MultiSelect = EditorType.ComboBox, SingleSelect = EditorType.ComboBox } })"
              ScaleMode="@ScaleMode"
              ViewMode="@ViewMode"
              PageMode="PageMode.SinglePage" />

public object BookReportSource { get; set; } = new Telerik.Reporting.UriReportSource()
{
    Uri = $"{ReportParameters.ReportName}.trbp"
};

protected override Task OnParametersSetAsync()
{
    switch (ReportParameters.ReportName)
    {
        case nameof(Report.StaffCapitalisationRatioReport):
            BookReportSource.Parameters.Add("StartDate", ReportParameters.StartDate);
            BookReportSource.Parameters.Add("EndDate", ReportParameters.EndDate);
            BookReportSource.Parameters.Add("BusinessUnit", ReportParameters.BusinessUnit);
            BookReportSource.Parameters.Add("FormatDate", Convert.ToDateTime(ReportParameters.EndDate).ToString("yyyy / MMMM"));
            BookReportSource.Parameters.Add("StaffNo", ReportParameters.StaffNo);
            BookReportSource.Parameters.Add("NormalWeekdayHours", ReportParameters.NormalWeekdayHours);
            BookReportSource.Parameters.Add("NormalWeekendHours", ReportParameters.NormalWeekendHours);
            break;
    }

    return base.OnParametersSetAsync();
}

I have created a REST Report Service in my .Net 8 MVC Project in Visual Studio. I can set Multiple Startup Projects and launch the debugger in Visual Studio, and everything works fine.

I will eventually need to have this REST service running on my IIS Server in production, but for now, I am attempting to get it working on IIS on my Windows 11 machine. 

I created a new REST Service using the Telerik template:

After creating the project, I launched the debugger, and the project launched a browser to http://localhost:59655/index.html with the message Telerik Reporting REST Service is up and running.

Still in Visual Studio, I have published the REST Service to a folder using the following settings:

In IIS, I create a new Site and App Pool with No Managed Code like my other .Net Core apps. I set the bindings to Port 59655 as it does in Visual Studio (not sure if this is necessary, or the wrong thing to do) but when I try to browse to http://localhost:59655/index.html, it gives the error: No webpage was found for the web address: https://localhost:59655. 

If I bind to HTTP instead of HTTPS, then I get the error: This site can’t provide a secure connection. 

So my question is, should I be using this port on IIS? What other settings must I change when publishing the app to a folder? There are settings in the launchSettings.json file that apply to IIS Express, so I don't think those apply.

I really have to figure this out before I attempt to deploy this to production, but I'm not really sure how to run the service with IIS.

Thanks for any help in advance.
