ASP.Net Error - inner stack trace reveals no line number - why?

MattMarx asked
Last Modified: 2007-12-19
I am currently experiencing an error on my page Pre_Render event.  There is quite a bit of code in there, so it is difficult for me to determine exactly what is causing it.

For other errors on my pages, I usually get a nice line number telling me where the error has occurred.  However, on this inner stack trace, I get NOTHING!  Why???

Here's the stack trace:

System.Web.HttpUnhandledException: Exception of type System.Web.HttpUnhandledException was thrown. ---> System.NullReferenceException: Object reference not set to an instance of an object.
   at MySite.TheMainPage.Page_PreRender(Object sender, EventArgs e)
   at System.Web.UI.Control.OnPreRender(EventArgs e)
   at System.Web.UI.Control.PreRenderRecursiveInternal()
   at System.Web.UI.Page.ProcessRequestMain()
   --- End of inner exception stack trace ---
   at System.Web.UI.Page.HandleError(Exception e)
   at System.Web.UI.Page.ProcessRequestMain()
   at System.Web.UI.Page.ProcessRequest()
   at System.Web.UI.Page.ProcessRequest(HttpContext context)
   at System.Web.CallHandlerExecutionStep.System.Web.HttpApplication+IExecutionStep.Execute()
   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

>Object reference not set to an instance of an object.

That's the problem....and as Silvers mentioned, you're referencing an object that has not been Set.  Check all you objects....if you're usnig Visual Studio (code behind), it should show you where the problem is....
