Problem
You’re trying to use the ReportViewer control in Visual Studio but it’s not in the toolbox.
Other symptoms:
- After manually adding the ReportViewer control to the toolbox clicking Design a new report does nothing.

- The RDLC report designer does not open and opening the RDLC file just opens the report markup.
Solution
Note: I am using Visual Studio 2017
Step 1 – Install the RDLC Report Designer extension

Step 2 – Add ReportViewer to the toolbox
