The following error may be thrown when trying to render a report in PDF under .NET 5 in the Linux systems:

"SEH":"System.ArgumentOutOfRangeException: Index and length must refer to a location within the string. (Parameter 'length')
          at System.String.Substring(Int32 startIndex, Int32 length)
          at Telerik.Reporting.Paging.TextBox.MeasureText(String text, TextFormat format)
          at Telerik.Reporting.Paging.TextBox.CreateContent(InitializationContext initContext)
          ...

The same reports work correctly in Windows.

In some cases, when the path of the file is used as a Value of the PictureBox, the WMF is not displayed in PrintPreview or in the printed report. The workaround is to embed the image by selecting the file as a Value:

1. Go to the Value property of the PictureBox and click on the three dots (...)

2. In the File name field, type *.* and Enter.

3. Select the WMF file.

When applying the property Docking with either of the following values will cause the Visual Studio Report Designer to squeeze the table down to 0 width:

• Top
• Fill
• Bottom

While the value 'Right' will cause the table to be rendered outside of the report-section on the left side. This is reproducible with the example report CryptoCurrencies.cs.

Hello, 

I can see that we can operate over a file definition using save, open, and save as. It would also be nice to be able to download the report definition as well. 

The application is published as a single-file application on Linux. Here is the stack trace of the error:

I also had lots of issues trying to get the application version information of a single-file application and had to revert to using an environmental variable in the container.

I have configured Asp.NET Core 5 IReportServiceConfiguration in DI for ReportsControllerBase with ReportServiceConfiguration.ReportingEngineConfiguration set to IConfiguration with custom IConfigurationProvider providing ConnectionStrings which can change in runtime so the provider notifies about configuration changes via IChangeToken.

But the updated ConnectionStrings are not propagated to the service.

To fix it, I have made this hack:

                reportEngineConfigurationChange = engineConfiguration.OnChange(() =>
                {
                    telerikConfigurationManagerReset();
                    configuration.ReportingEngineConfiguration = engineConfiguration;
                });

which listens to IConfiguration changes and calls TelerikConfigurationManager.Reset (via reflection) and sets configuration again.

It would be nice if this would be implemented on Your side, please.

Hello

I have problem with visual studio auto close when I'm working in reporting designer.

When I'm working in reporting designer and do about 5 changes, Visual studio freezes and after few monents is restarted and I loose all my work.

It is really frequented problem and I can hardly work with reporting designer.

In Windows Event Viewer I everytime find this exception that referes to problem in GetAggregateFunctions().

The SVG image is not rendered correctly. A sample report and the SVG can be found attached.

The designer outputs as on the picture below which is not correct:
