Scripting (Runtime)

Event Handler Parameters



Identifies the Silverlight plug-in that invoked the event.



Identifies the error and provides information about its source location. For more information, see ErrorEventArgs.


The OnError event provides the means to specify a user-defined JavaScript error handling function that is invoked when an error is generated in the Silverlight runtime components. The default value is null. If you are using the JavaScript helper file, Silverlight.js, and do not set the OnError property to an error handling function, the default error handling function, default_error_handler, is used. For more information on setting this event during plug-in initialization, see Instantiating a Silverlight Plug-in (Using CreateSilverlight.js and Silverlight.js).

For more information on Silverlight errors and error handling, see Silverlight Error Handling. For a list of error messages associated with this event, see Error Messages.
