TraceContext Class

Definition

Captures and presents execution details about a Web request. This class cannot be inherited.

public ref class TraceContext sealed
public sealed class TraceContext
type TraceContext = class
Public NotInheritable Class TraceContext
Inheritance
TraceContext

Remarks

You can use this class to append messages to specific trace categories. For example, if you are creating an instance of the Calendar class for your application, you might include the trace message "Starting To Render" in a rendering procedure, and "Raising OnChange Event" in an event handler procedure.

You can also use the TraceContext class to obtain a set of trace records at the end of request execution for custom processing. For more information, see ASP.NET Tracing Overview.

To enable tracing, set the Trace attribute in the @ Page directive or the IsEnabled property to true. When tracing is enabled, in addition to showing user-provided trace content, the Page class automatically includes performance data, control-tree structure information, and state management content for every request.
