On using the Page, RDLX, or Section report template, the Viewer control is already available on the Windows Form. The control is also available on the Toolbox under ActiveReports 18 tab, with the controls in sync with the references.

To add Viewer control to your WinForms Application,

1. In Visual Studio 2022, create a new Windows Forms App or open an existing one.
2. Install NuGet package for 'MESCIUS.ActiveReports.Viewer.Win'. For more information on installing NuGet packages, see Manage ActiveReports Dependencies topic.
3. Open WinForms Designer (Form1.cs or Form1.vb) to verify the Viewer control showing up in the Visual Studio Toolbox under 'ActiveReports 18' tab.
   To show the Visual Studio Toolbox, navigate to View > Toolbox.
