Hi,

I am currently working on a WinForm project in VS2019 that involves adding a report.

I have created a report using SSRS and need to embed it into my main application, however, I have been unable to add a report viewer control to my form without any issues and it is beginning to become frustrating as no online solution has helped.

The current error:

What I have tried:

  • Installed all reporting extensions needed
  • Installed multiple reporting nuget extensions

And still I have been unsuccessful in using the reportViewer.

Any help with installing and running the reportViewer successfully on VS2019 would be great

    Hi @Mikhail Govender ，
    Do you mean that the report viewer control could not be found in the toolbox? To add it to toolbox, you can click on Choose Items and then Browse your solution directory and from the NuGet package folders go to report viewer package folder and select Microsoft.ReportViewer.WinForms.dll.
    You could refer to the document: Integrate Reporting Services Using the Report Viewer Controls-Get Started.
    I think it’s easier to understand through the video：
