The print functionality cannot be used in Google Chrome 77.0.3865.75 (lastest update).  The following error is displayed in the console of the browser: Resource interpreted as Document but transferred with MIME type application/pdf.

As an alternative, you can use other web browsers for printing. 

It would be nice, if not required by our client, to have 100% Web-based, Rich, Ad-hoc Reporting Solution.
Something similar to the one in ComponentOne Active Report 

The Telerik Reporting only support fixed size page now.
But sometimes we need continues-roll paper mode.(like: receipt paper)

Some reporter tools: ActiveReports, it has 3 mode:(Page Reports,  RDL Reports,  Section Reports)

On "Telerik Forums / Reporting Forum" there is already some people asked it before 2 years ago. But until now the basic feature not release....

After R1 2019 Telerik Web Report Viewers use Kendo splitter for resizing Parameters and Document map areas. At this point, there is no way to change the Parameters Areas position.

If the controls and PDF generated from Designer or API from scratch will be 508 compliant? PDF needs to be tagged, so when a reader reads its images have text alternative for it to read.

Have control on the Parameters Area's initial state on creating the viewer

If during the report rendering stage, one or more of the required entities in the File storage were removed/deleted by third-party software, it will prevent the report from finishing the rendering and throws a NullRefereceException:

System.NullReferenceException: Object reference not set to an instance of an object.

   at Telerik.Reporting.Services.Engine.Document.FinishRendering(ReportRendererResult result)

When dynamically create a new tab which contains a report viewer, only the first report is rendered correctly. The subsequent tabs with report viewers are empty.

I need the ability to get the selected printer settings out of the printer dialog box once the user has selected their options and hit print/apply. I need this information in the PrintEndEvent in order to find out where the user is printing to (pdf or to a printer). 

Hi Support Team,

 

There an issue  for exporting  report to PowerPoint when there is grouping in table and tables goes to next page, 

I got this error : "The given key was not present in the dictionary"

I've attached sample trdx file for your consideration.

 

Thanks,

Mozhgan Javadi

Using the following code for updating the ReportSource of the viewer:

ngOnInit() {
  this.setParameters();
}

setParameters(): void {
  this.reportViewer.setReportSource({
    report: 'SampleReport.trdp',
    parameters: {}
  });
}

comes up with the error 

Argument of type '{ report: string; }' is not assignable to parameter of type 'JSON'.
  Type '{ report: string; }' is missing the following properties from type 'JSON': parse, stringify, [Symbol.toStringTag]

Currently, the workaround is to cast the reportSource object as follows:

ngAfterViewInit() {
  this.setReportSource();
}
 
setReportSource(): void {
  let rs = {
    report: 'SampleRepport.trdp',
    parameters: {}
  } as unknown as JSON;
  this.viewer.setReportSource(rs);
}

The MS Access OLE DB provider is not providing the correct QuotePrefix, QuoteSuffix, QuoteAlias that is causing errors in the SQL Query Designer that is part of the Standalone Report Designer.

When exporting a report with Crosstab which data source doesn't have any data, and the NoDataMessage property is not set, the report designer/viewer throws an error with message "Index was outside the bounds of the array”

When attempting to export a report in Excel 97-2003 format, an exception is thrown: 

"The type initializer for Telerik.Reporting.Excel 97.Workbook threw an exception. Object contains non-primitive or non-blittable data."

As HTML, PDF and OpenXML-based renderings are supported on Linux/macOS machines, please remove the old Excel 97-2003 format.

When trying to set the 'parametersAreaVisible' option in the Angular viewer the application breaks with an error in the browser console:

"Can't bind to 'parametersAreaVisible' since it isn't a known property of 'tr-viewer'."

I would like WPF viewer to behave like WinForms viewer and to keep the content of the rendered in XAML report in the page area in case of exceptions when exporting in other formats.

A valid URL, part of which is '/respuestas%2F138%2F116?' contains the substring '%2F' that is the URL Encoding for '/'. The image from the URL can be successfully opened in a browser. It cannot be resolved properly from the Reporting engine, as the actual request made for the image (as seen in Fiddler) contains '/respuestas/138/116?' instead of the original part - note the '/' replacing the original '%2F", which is not valid and causes a '400 Bad request' error.

I want to define conditional formatting on table row, after I define a filter and save it, I can not save the conditional formating dialog, it gives exception.

What am I doing wrong?

 

With the recent release of StackExchange.Redis v2.0 there are HARD BREAK changes. I would like Telerik Reporting to work also with this version.

I'm not a PDF expert, but if something can be done in a free library, a pay'd version of reporting tools should do it also right.

In many cases, I do a report to PDF for my clients. Since PDF contains useful data, I't normal to assume, client will use copy-paste and copying data to Word, Browser, etc.

Similar approach was used, when I created a project for the General prosecution of SR, but there the PDF was generated by PdfSharp and by writing text-outputs (with esired font, size, etc.). The result was correct.

Unfortunatelly with Telerik it's not so. I've tryed to explain it in a ticket, but I only got excuses, explanation about lignatures and so. I got/left myself almost convinced, but my main point is the starting sentence in this description.
