How to find line # of code that this error occurs?

My asp.net website logs errors when they occur, but only sometimes shows the line of code where it occurred. Is there a way to find out what line of code my error is occuring on when the line is not provided?

My Global.asax logs the error with the following code: 

   Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs)
    'Get MemberNumber
    Dim MemberNumber As String
    MemberNumber = User.Identity.Name.ToString
    If Len(User.Identity.Name.ToString) < 1 Then
        MemberNumber = "Guest"
    End If

    ' Code that runs when an unhandled error occurs
    Dim objErr As Exception = Server.GetLastError().GetBaseException()

    Dim ErrorDescription As String = "<b>Error Caught in Page_Error event</b><hr><br>" & _
 "<br><b>Member:</b> " & MemberNumber & _
 "<br><b>Error in: </b>" & Request.Url.ToString() & _
 "<br><b>Source Error:</b><br>" & objErr.Source.ToString() & _
 "<br><b>Error Message: </b>" & objErr.Message.ToString() & _
 "<br><b>Stack Trace:</b><br>" & _
 objErr.StackTrace.ToString()

    ErrorDescription = ErrorDescription & "<br />&nbsp;<br /><b>Form Variables</b>"
    For Each x As String In Request.Form
        If Trim(Request.Form(x).ToString).Contains("__VIEWSTATE") = False Then ErrorDescription = ErrorDescription & (x & ": ") & Request.Form(x) & "<br />"
    Next

'LOG ERROR cms.Application_Error_Log_Add(ErrorDescription) End Sub

I am trying to find the line on which the error occurs for this:

Source Error: Microsoft.VisualBasic

It looks like the checkbox labeled "ckAdmin" is causing this error, but I do not know how to trace it. How should I go about tracing down this error or finding the line of the code this error occurs in?

I suppose you could poke around in StackFrame, but that assumes that information is available (not running Release without Symbols, etc). Why not use ELMAH?
