It would be nice to have a report viewer component that does not rely on the full .net framework as described here.  https://docs.telerik.com/reporting/html5-report-viewer-asp-net-core-2.  I have a project that is not built against the full framework and would like to integrate reporting without converting all of my projects.

What's the long-term plan for supporting Linux and Telerik Reporting? The dotnet design team is looking to remove support for System.Drawing.Common on Linux platforms. They're recommending compiler warnings in .Net 6, and full PlatformNotSupportedExceptions in .Net7

Breaking change: System.Drawing.Common only supported on Windows - .NET | Microsoft Docs

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 Web Report Designer's current layout is not flexible and cannot be customized. It will be useful to allow changes in the designer template, styles, etc.

For example, in some scenarios, the users should not be allowed to add DataSources to the report. In this case, the DataSources components should be hidden or disabled, which currently can be achieved with custom jQuery code.

In other scenarios, it may be necessary to change the styles of the designer elements.

It will be useful for the designer to expose also events.

For our Customers a major drawback to creating form type reports (Invoices, Purchase Orders etc.) using Telerik Reporting is the inability to show vertical dividing lines between data columns in the 'Detail' section of the report that extend all the way down the page to the Page/Report footer. We were able to do this with Crystal Reports. But we plan to migrate all our Crystal reports to Telerik.

Currently, if you wish to hide extra details on the second page of a report, the space taken up by the area is left blank which looks terrible and not conducive to professional report design.

Unfortunately using report books for this is not a valid option.  Using the Report Book means quite a bit of extra work when all you need is for the second page to not have an glaring empty space.  If I understand the process correctly, this means creating 2 reports which are nearly duplicates plus merging with Report Book for each 1 report that you are developing.  This is unresonable to expect from enterprise shops that will develop hundreds of reports.

I urge you to review your implementation in order to find a way to implement this feature in the future. 

It would be good if the table headers can be frozen.  This can  be really useful in case of a big report which is displayed on a single page.

Support to display a SVG file in the PictureBox. When viewing a report this looks fantastic and of course superb for printing.

Please add support for Data Matrix barcodes.  As of Q3 2014 this is the only format we will still need to rely on another library to create an image that is placed in a picture box.  We would much rather be able to use the Barcode control for all our barcode requirements.

We need the ability to let a table group to initiate a page break.  When you have a table with hundreds of row breaking the into separate pages per group would make the report look so much cleaner.

When generating a report with multiple tables provide the ability to send these tables to different workbook tabs when exporting to Excel

Interactive sorting would really help the HTML5 based report viewer hold it's own against SSRS.

Optimize the Telerik Reporting performance by parallelizing the reporting paging and rendering. Better utilize CPUs with multiple cores and as a result, improve the REST Service throughput and decrease the viewers' rendering times.

Currently Telerik Reporting team like only a single developer hard working. So slow..... I even doubt there is no one here.
I hope hire more developer for Telerik Reporing team, and speed up. 
Or maybe Telerik Company even don't care "Telerik Reporting".  If that's true, please just close the project. Let us find another company request new feature and bug report who really care the customer.

Look it here. non finish request and problem already a hundred, even some request submit almost a year ago . But only 1 in development.
That's really not respect customer like us who really support The Telerik.

To have a better performance would be nice to cancel report rendering automatically or manually. 
If I am asking for a big report and after I change parameters and request new report, the previous request is still in progress and it is not going to be cancelled. Therefore I see high memory consumption on continuously refreshing a reports with a big data and after some time I see complete slow down of the Reporting Service and of course slow down of the server itself. The memory in this case is not released and Reporting Service crashes sometimes.

Allowing custom actions would greatly increase the power and flexibility of reports and the report viewer.  While the current set of actions provide great functionality, they are still somewhat limited in scope.  If actions were able to handle their own execution instead of having the individual report viewer implementations handle their execution, customers could enhance the functionality as they see fit.

Hello,

It would be nice if telerik reporting get a option tool which our customer can digitally sign a PDF generated from the telerik report.

This feature ll be great for the contract , important customer document, to sign in by the web.

thanks
Oliver

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....

Generate and distribute packages built against .Net 5.0.

Currently .Net 5.0 RC1 and .Net 5.0 RC2 are announced. The official version has been announced on 10th of November.

As a developer
I would like to have a built-in support for rendering various gauges in the report content
So that I can represent numeric values in a visually appealing way.
