The Language property on a report or a text box contains the locale setting, which determines the default formats for displaying report data that differ by language and region, for example, date, currency, or number values. The Language property on a text box overrides the Language property on the report. If no value is specified for Language, Reporting Services uses the locale of the operating system on the report server for published reports or of the report authoring computer for report preview.
For HTML reports, you can override the default Language value and use the language specified by the HTTP header of the browser client by using the built-in field User!Language in an expression for the Language property of a report or a text box.
You can also specify the Language property for a report in a URL. For more information, see Set the Language for Report Parameters in a URL.
