我的asp.net网站会在发生错误时记录错误，但有时只会显示发生错误的代码行。有没有办法找出我没有提供行时出现错误的代码行？
我的Global.asax使用以下代码记录错误：
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 /> <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中） 结束子
我正在尝试找到发生错误的行：

看起来标有“ckAdmin”的复选框导致此错误，但我不知道如何跟踪它。我该如何追踪这个错误或找到这个错误发生的代码行？
