Application_error Function Intermittently Catch "File Does Not Exist"?
Jul 14, 2010
I am using Appilcation_Error event for handling the exceptions and it catches almost all exceptions correctly. However in some pages it catches with some exception "File does not exist" and I am not able to find from where it exactly occurs. When I comment the Application_Error code, surprisingly that web page works fine.
My main concern is how can trace back to the line of code from where it threw to Appilcation_Error function.

Looking for best practice focused answers here with explanations.
Should the presentation layer of an ASP.Net app catch and handle exceptions thrown from the business layer, or should these be allowed to bubble out, where they can all be logged and handled uniformly in the Global.ascx's Application_Error handler?

I am trying to use the Application_Error to redirect the user to a custom error page. I know I could use the web.config to do this, but let's assume for now that this is not a desirable path to take.
Initially, I tried to do a Response.Redirect to perform this, however, there seem to be occasions where the current http context does not define the response object. So, I attempted to perform a check to make sure that the response object is not null prior to attempting the redirection, and if it is not defined, perform a Server.Transfer instead.
What happens is that in most cases, the Redirect causes the browser to some generic "friendlyish" error page rather than the requested error page.
So then I tried using Server.Transfer exclusively, and this worked well for most cases, however, sometimes the transfer didn't seem to take in the browser. Changing it back to a redirect in these cases solved that problem, but reintroduced the issue where the errors previously being captured and transferred now were being redirected.
What I surmised from this is that in certain contexts where the Application_Error method is trapped, it is necessary to use Server.Transfer in redirection, whereas in others, it is necessary to use Response.Redirect. The question then became twofold: (a) When is one necessary and when is the other? and (b) What available information can I poll to tell me when a given condition exists.
After much searching, I cannot find a reasonable answer to this question. So I began to trap errors and examine the HttpContext object for some indicator. One thing that I was looking for is the reason why if even with a defined Response in the current context does a redirect fail. The only thing that stood out is that even though a Response object may exist, the Session data could be absent. I added the case to check whether the Session data was null and perform a Transfer in this case and it
seems to be handling it properly.
I emphasize "seems to be handling it properly" because no documentation I've been able to find confirms either the problem I am having or whether this is an appropriate strategy for solving it.
I guess the question is, am I on the right track here or is the null Session object just a red herring, indicative of nothing relevant. Here's the check I have set up for reference.

I just got a new desktop computer with Windows 7 Pro as the operating system. I installed Visual Studio 2008 on to this new computer and tried to open a previously existing ASP.NET 3.5 solution that displayed perfectly fine on my previous computer (this previous computer used the Windows XP operating system, IIS6, and IE7 browser). However, in Windows7/IE8, I'm receiving the following error:
Server Error in '/' Application.
Parser Error Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.
Parser Error Message: The file '/MasterPages/MainMaster.master' does not exist.
Source Error: Line 1: <%@ Page Language="C#"
AutoEventWireup="true"
CodeFile="default.aspx.cs"[code]....
when I tell you that the file '/MasterPages/MainMaster.master' file does, in fact, exist. In addition, this file's location is properly referenced in the code (as indicated in Line 1 above), and as I said, was displayed properly by the browser in my previous computer. It might also be helpful to note that I've tried to navigate to other pages in this site, and this browser displays the same message for any and all master pages located in my MasterPages folder. In summary, for some reason the browser cannot see any pages in the MasterPages folder. Can anybody tell me why I'm getting this error message when the folder and file is exactly where default.aspx says it is?

Here is the code copied from [URL] In asp.net code behind, I use try-catch try to catch any error but never catch it. In SQL database, if I rename Employees to Employeesx or change column DepartmentID to DepartmentIDx, record will not be deleted (it is right) without any error (it is wrong, suppose catch an error).
CREATE PROCEDURE DeleteDepartment
(
@DepartmentID int
)
AS
BEGIN TRANSACTION
DELETE FROM Employees
WHERE DepartmentID = @DepartmentID
IF @@ERROR <> 0
BEGIN
ROLLBACK
RAISERROR ('Error', 16, 1)
RETURN
END
DELETE FROM Departments
WHERE DepartmentID = @DepartmentID
IF @@ERROR <> 0
BEGIN
ROLLBACK
RAISERROR ('Error', 16, 1)
RETURN
END

I have an ASP.net GridView with seven columns; the data comes from SQL. Two columns hold javascript that the user can click on to remove or modify an entry in the database. The other five fields contain names, phone numbers, and e-mail addresses of people in a database.
Four of my fields are ASP.net TemplateFields.
When the page loads, everything is displayed correctly. However, if a user clicks a JavaScript link, clicks to sort the GridView by any field, or does any other action that causes a postback, the resulting page may not display the contents of my TemplateFields; they are all blank.
Just so you can see what I'm working with, I have a "name" column which is defined like this:
<asp:TemplateField HeaderText="Name" SortExpression="name" ItemStyle-Width="150">
<ItemTemplate>
<%#(string)Eval("surname") + ", " + (string)Eval("fname") %>
</ItemTemplate>
</asp:TemplateField>
If I step thru the code in the debugger, I see that in the case that the template fields display correctly, the debugger stops on the line that displays the name. In the case that the fields are all blank, it jumps over the code to display the contents of those fields; and for no discrenible reason what-so-ever.
The only thing that seems to cause the problem is that there is a single enum value that is set from the query-string (which tells the page what data to load). When the enum value is set to 1, I never see this error, but it seems that I always see it when the enum value is set to 2.
However, the enum is never ever referenced anywhere in my gridview code.
In any event, the GridView.DataSource = x is always called and GridView.DataBind() is always called. I've tried stepping thru the code and checking that the data from the database is correct. I've tried debugging on the code block where DataBind is called from and also the GridViewRow_DataBound Event handler.
I've seen other posts elesewhere about trouble with TemplateField, but none of them seem to address what's going on here.

I come from a VB environment. I'm looking at 2 different file extensions. If one doesn't exist look at the next. I was hoping to use the try/catch function. I can get it to find the first extension but not the second. Here is my the try/catch part of code:
try
{
string website = xAll;
Response.Redirect(website);
}
catch (FileNotFoundException)
{
string website1 = xAll1;
Response.Redirect(website1);
}
The error dialog that pops up shows Connection Error in the title and a yellow exclamation point with File Not Found! I thought the FileNotFoundException would work(?).

protected void Button1_Click(object sender, EventArgs e)
{
try

}
catch(Exception ex)
{
}
}
I even created a global.asax file and on the Application_Error event, I wrote a code that would email me the error (and i'm not getting an email regarding that error when I get the error shown above). I know for a fact that the thread is going inside the "try" statement because I send emails to myself whenever it finishes certain codes inside of it. So how come I'm getting that error in my browser instead of it being handled in my "catch" statement? I have two problems here, one, why is the exception not going to my "catch" statement, and two, why am I getting that error in the first place.
Note: my web app calls a webservice.

intermittently manifested itself was an occasional 'Session closed!' error. Sometimes it would be on the second refresh of a page, and sometimes the first. There didn't seem to be any reasonable explanation. I set some breaks and stepped through it, and sure enough, there were times were the session spontaneously closed itself between two successive lines of code, with nothing else in between.As an experiement, I tried the UnitOfWork pattern, which worked right away. The only problem there is having to instantiate it in a using() block in order to fire Dispose().

When debugging my application, I m getting an application level error in global.asax file. The Server.GetLastError() reads "File does not exist." but thats it. No more details on the filename or the location where the code is trying to find a file. I commented out the application_error method, with a hope that the exception would be thrown when the debug the application, but no errors were thrown. How do i find the source of the error, cos I want to resolve this issue by either putting the file that the application is looking for or by completely removing the code that is referencing the file.

I've got a UserControl that's used inside of an UpdatePanel. The UserControl is a fairly simple form that appears via a ModalPopupExtender (which is also part of the UserControl). There are four DropDownLists, as well as some other UI elements. Three of the four DropDownLists have AutoPostBack="true", with SelectedIndexChanged events that fire on the server and cause some of the other DropDownLists to rebind. Two of the three DDL's that AutoPostBack are working fine. One of them, which I only just added, is showing some strange behavior. Let's say I bind five Items to it: 1, 2, 3, 4, 5. I set the SelectedIndex to 0, which makes 1 the selected item. If I select 5 and then 1 and keep toggling back and forth, everything works fine. The postback occurs and SelectedIndexChanged fires. Every time. If I ever select 2 or 4, the postback occurs but SelectedIndexChanged does not fire. Every time.
If I ever select 3, something bizarre happens and sometimes the value of the DDL reverts to 1. Even though breakpoints seem to show that it's not rebinding and no unexpected code is running. I know your first instinct will probably be that I'm wrong about the rebinding code not running, but I have literally been staring at the debugger for hours trying to find my mistake. Lots of breakpoints. I don't get it -- this really isn't that complicated. But obviously I am missing something. I've put about four hours into this so far and I think I'm just grinding at this point. I could use another perspective.
HTML (and by the way, DropProtocolCycleID is the problem control):
<asp:Panel ID="PanelPopupAssign" runat="server" Style="display:none; cursor: move; width:325px; background-color:Transparent;">

I am using master and content pages on my website and recently after rewriting some code and altering the table layout I am getting an issue when navigating through the pages. The problem being encountered is the random movement of text at the top of a table (two different words Scottish Premier & English Premier) , I changed them to labelsand still experience the same problems (intermittently). I cannot see any reason for the elements moving and it detracts from the visual layout on the screen. The problem occurs in both IE 8 and Firefox. The respective text/labels are on the masterpage
Is there anything I can do to track down the reason why it is happening? Why will a page render correctly sometimes and not others?I have copied the masterpage and one of the content pages to a different web address for anyone that wants to view the problem. (None of the buttons will function correctly however navigating to an invalid page then using browser "back" will on occasion display the problem with the Scottish Premier & English Premier label (They remain as labels for the time being)Here is the link to the cut-down version of the website:[URL]Below are two images, one is the correct layout, the other shows the labels that moved.

I have found the error below in my web log and I wonder what the cause may be.
The page indeed does not exist at the requested location.
Perhaps a request is incoming and ASP.NET is trying to compile that page?
But, I did not know a request to a non existing page would cause a compilation error.
Error: The file '/<X>/<Y>/<Z>.aspx' does not exist.
