Hi @sravya shivapuram ,
When you preview the report in ReportViewer, the report is rendered by the HTML Rendering Extension. After you export the report as a PDF file, you use the PDF rendering extension to open the report.
You could customize rendering extension parameters in RSReportServer.Config, please make a backup in advance. In Reporting Services, device information settings are used to pass rendering parameters to a rendering extension. Each rendering extension accepts a specific set of settings.
For more information, please refer to: PDF Device Information Settings.
Customize Rendering Extension Parameters in RSReportServer.Config.
Passing Device Information Settings to Rendering Extensions.
Best Regards,
Joy
