Rendering Extensions

A rendering extension is a component of the Telerik Reporting engine that transforms report data and layout into a device-specific format. By default Telerik Reporting outputs reports in the following formats: Image, PDF, HTML, MHTML, Excel 97-2003, XLSX, PPTX, DOCX, RTF and CSV. You can specify rendering extension parameters in your application’s configuration file to override the default report rendering behavior. The rendering extension parameters are specified as device information settings.

Adding device information settings to an application configuration file is useful when you want to override the default values that are provided by the reporting engine. Specifying device information settings in the configuration files affects rendering extensions globally. The settings in the configuration files are used in place of default values whenever a particular rendering extension is used. If you want to set rendering extension parameters for a specific report or rendering operation, you must specify device information programmatically using the RenderReport method. For more information about specifying device information settings for a rendering operation, and to view the complete list of device information settings, see Telerik Reporting Device Information Settings.

Caution
For Windows applications the configuration file is called app.config and for ASP.NET applications – web.config. For more information about configuring a .NET application, see Configuring Applications( http://msdn2.microsoft.com/en-us/library/kza1yk3a(VS.80).aspx).

Caution
All configuration settings on Telerik Reporting engine are applied only at runtime, not in design-time.
