In this article I will explain with an example, how to add ReportViewer control to Visual Studio 2019 Toolbox.
The Report Viewer Control is available in Nuget package and no longer shows in the Visual Studio Toolbox by default. So, you need to add the control to the Toolbox manually.
 
 
Installing ReportViewer Control from Nuget
First you need to install the ReportViewerControl package from Nuget using the following command.
For Web Form
Install-Package Microsoft.ReportingServices.ReportViewerControl.WebForms
 
For Windows Form
Install-Package Microsoft.ReportingServices.ReportViewerControl.WinForms
 
Once the package is successfully installed, the Nuget package will be installed in the solution directory of the project and the dll is available in the location as follows.
Windows – {Solution Directory}\packages\Microsoft.ReportingServices.ReportViewerControl.Winforms.{version}\lib\net40
Web – {Solution Directory}\packages\Microsoft.ReportingServices.ReportViewerControl.WebForms.{version}\lib\net40
