When certain fonts are used, the text of reports exported to PDF looks different between the Skia and GDI rendering engines, even if the fonts are fully embedded.

For example, if the TT Norms font is used and the report is exported to PDF (full font embedding) with both engines, the document rendered by Skia is much larger and looks different than the GDI-rendered document.

Since upgrade to openXML 3.0.0 we get exceptions at runtime when we want to create a report in XLS.

While a feature request has been filed here: https://feedback.telerik.com/reporting/1631967-openxml-renderings-should-work-with-documentformat-openxml-3-0-0-and-newer one could argue it is a bug. Anyway, i raise this issue here to have some extra attention to it.

The Standalone Report Designer allows users to add Anchoring to an item even if its container has KeepTogether set to False. This is not valid and can break report definitions without a warning.

The reports can be fixed by editing the XML code of the definition manually and setting the KeepTogether property to True.

We are trying  to create a Telerik report and in this report, we are  using a few sub reports for some parts of this report. In one portion of the reports I need to display multiple items (detail with description) and it should be rendered in two columns. To render the content into 2 columns I used the Column Count property and with this, it works fine when we run the subreport independently. But when we try to  use this  as  subreport in the main report then this ColumnCount feature is not working so please let me know how I can render a subreport content into 2 columns.Please see the screenshot.Sample image is the one we are trying to achieve in output .
Report design is the one we have designed for our work. When we run it independently it works but when we add it as a sub report to a main report it fails.Sample Sub report - the one working when we try it independently.

Conditional formatting property already exists in Telerik.Reporting.LegendItem class however does not exist on Telerik.Reporting.GraphLegend.

Would be great to have a ConditionalFormatting property into the Telerik.Reporting.GraphLegend to allows to perform bindings on this element.

Exemple of use case not possible currently: Bind the GraphLegend.Position property with an expression.

When I try to export a ReportBook to TIFF as explained in Exporting a report to a multi-document format, I receive an exception related to the file '.../report/image.tif' that cannot be created.

When I create the folder '.../report', there is another exception message:

'The process cannot access the file '...\report\image.tif' because it is being used by another process.'

The above error was thrown the second time the ReportProcessor tried to access the 'CreateStream' method from the code snippet in the above article. The 'image.tif' file is created and contains only the first report from the ReportBook.

With version 15.0.21.112 the last exception is not thrown and the 'image.tif' file contains all reports from the ReportBook.

Requesting a feature to allow some sort of selection feature on the "Send Mail Dialog". The issue that we're having is if the user needs to email a report to 5 or 10 people it becomes very daunting, ugly and difficult for them to achieve this without making errors in typing out every single email.

Also, in most cases the user might not know the individuals email official email address in the organization so they have to go look up every single one. If there was a drop down selection or an auto predict while typing then once clicked it grouped up the name to make it look cleaner and easier for them to find the email addresses that would be wonderful. Here's an example of what it looks like right now.

Telerik.Reporting.Services.HttpClient version

references a bad version of

Microsoft.IdentityModel.Clients.ActiveDirectory

That has inconsistent references as can been seen from this error (from System.Private.DataContractSerialization 4.1.1)

 

##[error]src\Cms.Wpf\Cms.Wpf\Cms.Wpf.csproj(0,0): Error NU1605: Warning As Error: Detected package downgrade: System.Text.Encoding.Extensions from 4.3.0 to 4.0.11. Reference the package directly from the project to select a different version.

This results in a publish failure with .net 8 where warning are treated as errors by default when publishing.

A workaround is to add
<NoWarn>NU1605</NoWarn>
to the referenced project.

I have a Multivalue Report Parameter in the report that gets fed by a data source and may have more than 1000 selectable values. It is a ComboBox.

When I search and select a value from the dropdown, the selected value may not be passed with the reportSource of the viewer if I click directly the Preview button, without clicking outside the selection popup first. The issue occurs randomly. If I click outside the popup first, the values are passed correctly. I cannot reproduce the issue with less selectable items.

When using the SqlDataSource component with a stored procedure that has an IF-ELSE condition which selects a different set of columns depending on whether the condition is true or false, the returned data schema is always as if the condition is evaluated to true.

While the schema is wrong, if I manually type the fields, at runtime, they get resolved correctly but it is inconvenient.

I had a report book with only a TOC report and when I previewed it, I was met with an "Object reference not set to an instance of an object" exception which did not make it clear what was causing the issue losing me a lot of time in debugging.

Once I added a report to my ReportBook the issue was resolved, however, the error message should be more meaningful.
