Web Viewer Migration
This topic explains how to upgrade the WebViewer control.
The ASP.NET Web form or the Web.config file included in the WebViewer control is upgraded automatically on running the ActiveReports file converter. However, the converter does not upgrade the Flash viewer since flash viewer is obsolete.
The license file should also get updated while conversion, but in some cases due to the project configuration, you may need to manually update the license file. For more information on upgrading license, see License ActiveReports.
You may run into problems while migrating in Web due to the following reasons:
- No more Flash application framework support
- No more Silverlight application framework support
- New Server API since ActiveReports 13
- New JS API since ActiveReports 15
Hence, to perform the Web Viewer migration, ensure following:
- Check for any web related breaking changes.
- If you are using old technologies (like Silverlight), we suggest migrating to Blazor.
- If JS API does not work, check the new JS Viewer API and Web Samples and restore functions.
- Contact our Support Team for help.
