I have recently upgraded to the new version of telerik 2018 R3. Now the parameterarea is not visible anymore.
1. I have reports with parameters visible
2. I added .ParametersAreaVisible(true) to the reportviewer just to be sure
3. Locally is works fine
4. When i look at the reportviewer where it doesn't work the button in the toolbar is disabled.
5. When i try to manually toggle the parameterarea it does nothing.
Any idea on how to fix this?
