TraceContext.TraceFinished Event

Raised by the TraceContext object to expose trace messages after all request information is gathered.

Namespace: System.Web
Assembly: System.Web (in system.web.dll)

'Declaration
Public Event TraceFinished As TraceContextEventHandler
'Usage
Dim instance As TraceContext
Dim handler As TraceContextEventHandler

AddHandler instance.TraceFinished, handler

/** @event */
public void add_TraceFinished (TraceContextEventHandler value)

/** @event */
public void remove_TraceFinished (TraceContextEventHandler value)

In JScript, you can handle the events defined by a class, but you cannot define your own.
Not applicable.

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>
