In order to see trace output in an ASP.NET application, you need to turn on tracing, which is typically done at the application-level in the web.config file. The trace setting can be found within the trace element:

<trace enabled="false"
requestLimit="10"
pageOutput="false"
traceMode="SortByTime"
localOnly="true"

To turn on tracing, set the enabled property to “true”. If the pageOutput property is set to “true”, the trace output is displayed at the bottom of each ASP.NET page. If it’s set to “false”, trace output is saved in a file named “trace.axd” found in your Web application’s root directory.
