I am using report viewer in a Blazor project.

 

The images in report do not show up in the report. However, they do appear when i try to print or export the report.

 

 

Please advise ?

Hi Tanveer,

Please continue this conversation in the support ticket you have opened with your other Telerik account. Neli form the Reporting team has already replied and is awaiting your repose. Refer to ticket #1478232.

For any future questions of concerns, please open support tickets using your main account as having a parallel trial support license in a different account to gain additional support is against the License policy.

Hi Gareth,

Thank you for your feedback. It is very appreciated. However, we usually don't delete threads. As a result, I would like to provide reference to most common reason for this below so that others in the community can reference this if needed.

Images Not Appearing

A common reason when images do not appear in a the Blazor or the HTML5 report viewer is unrelated to the report viewer itself. 

Instead, this is due to the configuration of the ASP.NET Core application. By examining error messages, the following error would appear. 

Synchronous operations are disallowed. Call WriteAsync or set AllowSynchronousIO to true instead.

This is due to .NET Core 3 disallowing synchronous operations. For more details, see the How to Host Reports REST Service in ASP.NET Core 3.0+ and the ASP.NET Core 3.0 Application the PictureBox and CheckBox Images are Not Displayed articles. 

Wrapping Up

I hope that the above articles will help you or anyone when images are not appearing in the report viewer. 

Please let me know if you need any additional information. Thank you.

Regards,
