How can error events be used to handle exceptions?

Apart from the try catch exception handling technique, the ASP.NET Framework has error handling events where exceptions can be caught. When there is an unhandled error at the code level, meaning if the code does not have a structured try catch block to handle exceptions, then that can be handled at the page level.
