TraceContext.TraceFinished Event
.NET Framework (current version)
Raised by the TraceContext object to expose trace messages after all request information is gathered.
Assembly: System.Web (in System.Web.dll)
The TraceFinished event is raised during the EndRequest stage of HTTP request processing. It is raised by a TraceContext object after all request information is gathered, to expose the collection of TraceContextRecord messages to registered TraceContextEventHandler delegates.
The following code example demonstrates how you can register a TraceContextEventHandler to handle the TraceFinished event. In this example, the delegate iterates through the trace messages and writes them to the response stream; however, you could write the same information to a database or a profiling tool consumer.
<%@ Page language="VB" Trace="true" %> <script runat="server"> ' The Page_Load method. Private Sub Page_Load(sender As Object, e As EventArgs) ' Register a handler for the TraceFinished event. AddHandler Trace.TraceFinished, AddressOf OnTraceFinished ' Write a trace message. Trace.Write("Web Forms Infrastructure Methods", "USERMESSAGE: Page_Load complete.") End Sub ' Page_Load ' A TraceContextEventHandler for the TraceFinished event. Private Sub OnTraceFinished(sender As Object, e As TraceContextEventArgs) Dim r As TraceContextRecord Dim o As Object ' Iterate through the collection of trace records and write ' them to the response stream. For Each o In e.TraceRecords r = CType(o, TraceContextRecord) Response.Write(String.Format("trace message: {0} <BR>", r.Message)) Next End Sub ' OnTraceFinished </script>
