Define Error Events.ASP.NET supports events that occur when any unhandled exception occurs in an application. These events are called as Error Events.
ASP.NET provides two such events to handle exceptions:
Page_Error : This is page event and is raised when any unhandled exception occur in the page.
Application_Error: This is application event and is raised for all unhandled exceptions in the ASP.NET application and is implemented in global.asax
The Error events have two methods to handle the exception:
GetLastError: Returns the last exception that occurred on the server.
ClearError: This method clear error and thus stop the error to trigger subsequent error event.
