Description

The content of the HTML5 ASP.NET WebForms ReportViewer is not updated on page reload. 

You may experience the problem in an attempt to refresh the page fully or partially.

Solution

The HTML5 ASP.NET WebForms Report Viewer has its PersistSession property hard-coded to True, allowing the displayed content to be preserved between requests.

A fix is available in the R1 2017 release, so if you are experiencing this problem, please consider upgrading or use the workaround suggested below.

Workaround

Replace the HTML5 ASP.NET WebForms ReportViewer with the pure HTML5 Report Viewer. It is the same viewer, where settings will have to be applied in JavaScript instead of C#|VB.NET.
