asp.net mvc exceptions tracing

asp.net, asp.net-mvc, debugging, logging

Solution

I guess your problem is that you are using the `System.Diagnostics.Trace` class instead of ASP.NET's tracing mechanism and it's not set to route trace messages to `trace.axd`. Try using `Controller.HttpContext.Trace` object for tracing.

Alternatively, try routing `System.Diagnostics.Trace` to ASP.NET tracing by adding the following snippet to `web.config`:

<system.diagnostics>
  <trace>
    <listeners>
       <add name="WebPageTraceListener" 
            type="System.Web.WebPageTraceListener, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>
    </listeners>
  </trace>
</system.diagnostics>

Problem

I am trying to send an exception caught in Controller to trace.axd page, but I cant seem to figure it out. I have ``` <trace enabled="true" localOnly="false" mostRecent="true" pageOutput="false" /> ``` in web.config, and my inteded reaction to an exception is ``` catch (Exception e) { ViewData["error"] += "Is not number!"; Trace.TraceError(e.ToString()); Trace.TraceError(e.StackTrace); return View(); } ``` However, I can't find either of those strings anywhere on trace.axd page. So how to get them there? Secondary, I want to ask, how should I turn off tracing not problematic (meaning those I do not personally send from some method) requests, since they just flood my trace and remove those occasional error reports sooner, than someone notices them. Thanks in advance.
