Hi ryoka012:
As for the report margin of ASP.NET Webform ReportViewer displayed report,are you using Server Report from SQL Server reporting service or local client report(rdlc file) in project? Based on my experience, for the Reporting Service report, the margins are
configured through the report page's layout setting and are stored in RDL
file(for server report) or RDLC file(for visual studio developed client
report). Whenever, you're designing a report, in the design-time "layout" view, you can configure the "margins" for the report through the following steps:
1.click on the background of the report
- In the property window, locate the "Layout" category and you can find
the "Margins" setting
After you change this margins setting, it will reflect to the exported PDF and TIFF report output. For normal HTML output, margin is not displayed.
Hope this helps.
