The best way to implement a report with multi-column headers and footers that contain report-specific data in the column

I'm trying to replicate a SSRS report that uses a DbContext for a data source. Each page of the report has a header and footer that contains data that is retrieved and display based on report parameters. I don't see any way to implement columns in the header because I can't place a table in the PageHeaderSection. I would love to hear some suggestions on how best to accomplish what I'm trying to do.

How to resolve an Array in a table column

Hello,

i have problems to resolve ExpensesData[] (Indexer,Array or what ever) in my table column.

Please see the attached file.

In the column "Fahrtzeit" I become the message --> ReportLibraryTest.DriverReportService.ExpensesData[]

What can I do to get to the data.

Is there an easy way to resolve contents of lists or arrays into table columns?

Thats the implementation of ExpensesData[] in the Webservice:

[System.Runtime.Serialization.DataMemberAttribute()]
        public ReportLibraryTest.DriverReportService.ExpensesData[] Expenses {
            get {
                return this.ExpensesField;
            }
            set {
                if ((object.ReferenceEquals(this.ExpensesField, value) != true)) {
                    this.ExpensesField = value;
                    this.RaisePropertyChanged("Expenses");
                }
            }
        }

thanks in advance.

Report Viewer Not Displaying Instance Report Source

I am trying to set up the report viewer to display a report using the InstanceReportSource. I want to use the InstanceReportSource because our application programmatically renders, compresses and downloads mass reports. I have followed this guide and have set up the rest service and custom resolver. I am using the same code to create the reports for rendering/downloading and for passing to the report viewer. The rendering and downloading works just fine but the report viewer is blank. During debugging, I can see the Reports API controller being hit and the resolver creating the InstanceReportSource.

I have created a a sample application that shows how I am using the reporting service. I'm sure that I'm missing something minor. I just can't figure out what. Any help would be much appreciated.

Picturebox with Image url not working in multiple projects

I have a Telerik Reporting Library 2019 project which contains Telerik Reports. The reports are consumed from a ASP.NET Core web application when controller actions are called. So there is a reference to this Reporting library project from Web project.

In the web project I create a ReportBook to generate report. and render the report as a PDF.

[HttpGet("{reportId}", Name = "Report")]

public async Task<IActionResult> Get(Guid reportId)

{

//Report Book

var reportBook = new ReportBook();

var instanceReportBookSource = new InstanceReportSource

{

ReportDocument = reportBook

};

//Cover Page

var coverPageReportSource = new InstanceReportSource();

var coverPagereport = new CoverPage(reportId)

{

DocumentName = "Cover Page Report"

};

coverPageReportSource.ReportDocument = coverPagereport;

reportBook.ReportSources.Add(coverPageReportSource);

var reportProcessor = new ReportProcessor();

var renderingResult = reportProcessor.RenderReport("PDF", instanceReportBookSource, new Hashtable());

var fileName = renderingResult.DocumentName + "." + renderingResult.Extension;

var path = Path.GetTempPath();

var filePath = Path.Combine(path, fileName);

using (var fs = new FileStream(filePath, FileMode.Create))

{

fs.Write(renderingResult.DocumentBytes, 0, renderingResult.DocumentBytes.Length);

}

var output = renderingResult.DocumentBytes;

return File(output, "application/pdf");

}

In the reports I have few PictureBox components. I want to set pictures from a http url (https://docs.telerik.com/reporting/report-items-picture-box#data-binding)

Example

1.var pictureBox = ((Telerik.Reporting.PictureBox)(reportDef.Items.Find("pictureBox1", true)[0]));

2.pictureBox.Value = "https://d585tldpucyb98b4-413e94c0e92bvanemkallan.jpg"; //Some Image URL

But when I try to do that it always gives an error (report-error.png). Is this because I have report definition in one project and consuming it from another project (web project). How can I solve this.
