At the moment it's only possible to have your reports in old-fashioned projects.

It should be possible to add/design reports to SDK-style projects. That should work no matter what target framework is (.NET Core, .NET Standard or .NET Framework).

If I do not have any report opened in the Web Report Designer, and then open the Asset Manager, I am not able to close the Asset Manager afterward.

Instead, when I click on the 'X' button to close the Asset Manager screen, I get the following error:

Uncaught TypeError: this.designSurfaceManager.ActiveDesignSurface is null
    updatePreviewButtonState http://localhost:51864/api/reportdesigner/designerresources/js/webReportDesigner-
    restoreMainMenu http://localhost:51864/api/reportdesigner/designerresources/js/webReportDesigner-
    createAssetManagerOverlay http://localhost:51864/api/reportdesigner/designerresources/js/webReportDesigner-

The 'Workspace Preferences' view also cannot be loaded in this scenario(no report).

When I am sending an email through the native Blazor Report Viewer and I type in the CC field, even if I delete what I have typed there, an "Email format is not valid" error will be displayed below the input and I will be unable to send the email.

This does not occur if I do not type in the CC input at all and it also works if I provide a valid email there.

Export the images to Word with the new "graphic" and "pic" tags instead of the VML tags.  The VML is an obsoleted feature no longer used nad such shapes cannot be properly edited in Word. In addition the WPF and Winforms RadRichTextBox do not support them as well.

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

It would be lovely to be able to string multiple emails in the "To" and "CC" fields so users could email a batch of users at once. In my scenario there is an email distro group that needs to get a report when printed. I could write logic to pass multiple email accounts into the "CC" field, however, the functionality doesn't exist. Below is a visual example of what I'd like to achieve.

I'm changing the font color to Transparent based on a condition in my report.
This works in the Standalone Designers for .NET and for .NET Framework.
In the WPF Report Viewers for .NET and .NET Framework though the Transparent color is not respected. Other Font colors like green are properly shown conditionally in the WPF viewers.

Currently all of the generated cell values are marked as values rather that formulae. However, there is no additional escaping logic that ensures that Excel will not treat values that start with formula identifier as formulae. In order to mitigate this behavior, such an option should be added in the export parameters similar to CSV FormulaPrefix

Use only components from KendoUI for Angular. It would be understandable that such report viewer would provide less features, but it would remove dependency from jQuery and KendoUI for jQuery.

So there is an Angular report viewer of sorts, but the report viewer web api component doesn't work with .net core (must target 4.6.1) and the angular component doesn't work with universal/server side rendering.  It would be great if this could get fixed!

The attached 'Test.svg' image markup file contains 'use' statements that lead to duplicating part of the image parts when rendering the report in PDF.

The other file in the archive, 'Test-noUsings.svg' is the same image without 'use' statements and doesn't have this problem.

As a developer, I need to be able to align an image that is scaled proportionally in top-left for example, so that it looks more aesthetic and as required from the clients who use for example logos of various sizes. I.e., my expectation is that I should be able to specify both "Scale Proportional" AND Image Alignment, both horizontal and vertical.

When we create a report and when previewing the report it may show an error because the OData query of WebServiceDataSource is not correctly designed, etc. This can help us to debug our report.

There is no way to send a bearer token with the requests to the reporting service made by the native Blazor Report Viewer because the viewer does not expose a property for setting the token.

It would be very useful if the report parameters of all the HTML5-based report viewers become accessible from the report viewer widgets.

For example, we are currently working on a report that has a custom button that sends the current parameters to an API and "signs" the current report (e.g. saves a string in the database and displays it afterward in the report).

We would like to validate if the currently shown report matches the report parameters but are unable to find a valid solution for this scenario.

The fix to the bug TOC page numbers and total PageCount are incorrect in some scenarios provided in R2 2023 may have led to another bug, as when I render my report with TOC the total page count is not correct in PrintPreview, although the page number is correct.

For example, on the last page, I see page 126 out of 123.

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.

When using the Report Viewer under WinForms, Print Preview allows the user to scroll through all report documents.  I.E., everything in the document map.  However, when using the Wpf version you cannot.  In the Wpf version, the user must use the Document map to select and scroll through each particular area.

For large reports containing multiple documents, this is tedious.  

Please make the Print Preview functionality for the WPF control match that supported by the WinForms control.
