So on my master page I would have the following this is where the content goes So when I would submit a content page, placeholder named "ErrorPlaceHolder" would be found and error would be displayed in the pages "Pre Render" event..I guess.

I have been tasked with implementing a strategy to catch all errors in an ASP.net application which cause a user request or interaction to crash and then e-mailk this exception to a support team in advance of a user calling about the error.Some errors however are not causing the page to crash or be redirected to the custom error page but these are being emailed to the support team instead of simply being loggedMy requirement is to seperate what exception types will cause a page fail and which will not.Example I am currently receiving a System.Web.HttpUnHandledException which is not causing any page to fall over and therefore is not of relevance to the support team. this can be logged but does not require emailing.
When a server error occurs for whatever reasons (YSOD), the server will send a message via SMTP class. In my case, my company employs microsoft exchange and uses NTLM authentication for all domain users. I am authenticating users via NTLA windows integrated authentication. My question is, is it possible to utilize this authentication data, and pass it to the system.web SMTP username/password authentication scheme to send an email to me (the web developer) when the error occurs? I am pretty sure my company requires a username/pwd to send emails via SMPT on the ms exchange server.
I have a folder "Admin" having access to administrators role. When someone other than administrators tries to access the pages inside admin folder, it is redirected to login page. My expectation is to display "NoAccess.aspx". Whats wrong with this code? Or is there other meaning to statusCode=403.
Using VB.Net 3.5 framework, i have a site that is using a custom login form and custom error with custom error page in global.asax and web.config is set up for both the login form and custom error. All works fine: my users login and when they get an error, they get the custom error page. The pages also use querystrings when moving about the site in order to retrieve data from a data base using a customer name (this is not the login name) and order number. When an error occurs anywhere in the site, I'd like to pass the page name and its querystring parameters
(ex: page1.aspx?a=1&b=2) to the custom error as well as the user information so that all the user sees is the custom error page telling them the error and all details were sent to the admin. Currently, the custom error page has an email link so the user can send a message that includes the details which results in 2 emails being generated for an error: one from global.asax with the error info/stack trace and the one the user sends with the details.
In my mind, a graceful failure does not require input from the user, just an apology and assurance the problem has been fully reported and will be taken care of. So, can someone assist in getting the current user and page/querystring into the custom error code in global.asax?
I have all my errors handling up and going but now I wish to change the error messages that they display for empty integers.I have been going through my codes but I can't to change that. For now, the error message for all numeric values are "A values is required" and I wish to change it to "<TextBoxName> cannot be empty".

Possible Duplicate: Best practices for exception management in JAVA or C# I am using class libraries and I try to put maximum code in class libraries so that it can be reused in other projects.Please advice me where I should put try catch blocks in class library functions or in front end forms (aspx pages) ?
I want to do a bulk insert of data from a tab-seperated file into a MSSQL database using Linq to SQL. I have put all the inserts lined up on InsertAllOnSubmit(). Now, can anyone tell me if an exception occurs in one of the inserts, do the previous inserts rollback or the process stops or it skips that insert?
Does it make sense to do error handling and logging inside actions methods or handle the OnException method inside the controllers. One way means writing try/catches in all the action methods even when there is nothing to be done to recover from the error. Handling this at the controller level would allow logging and redirection to an error handler page without writing try/catches inside all the action methods.
Which method makes the most sense? Here is example code of try/catches in an action method.
[HttpPost] public ActionResult Delete(int id) {[code]...
i have a webpage built in asp.net c#. it always a user to create a new record in a db table. there are there are two input fields, text and score. text cannot be a null value so if the user doesn't input text onsubmit, the page errors out. i want to throw in some simple error handling code in the code behind page. i've tried including an if/else on_inserted method but ran into some java script errors.
I've been tasked with creating a class that will handle errors in my Web application. I'm told the goal is to have a separate .cs file that can be called to handle any errors that come along. I have no idea where to begin, and I've googled but I don't think I'm googling the right thing because I'm not really finding anything.
I created an ASHX file and use it to handle async file uploads.Since the site might not be hosted on our servers, I want to check for write permissions and delete permissions and supply the end user (site content editor in this case) with an error they can deal with.
Im using uploadify for the upload, Im not sure, but I`m guessing this complicates the return of a message that can be shown on the page, but maybe not.
I need to create application wide error handling mechanism. I was evaluating Action Filter for that matter. But- Action filter will just exectute against actions/controller- what about error at custom view engine or Extension method for HTML helper.: to handle them i need to implement traditional Asp.net mechanismCan anyone suggest best common approach which can handle error for all Controller, View, Model or custom helpers if any.
I use Custom errors in my web.config. It works for urls like www.x.com/x.aspx , but when I write something like :
www.x.com/name (I have Application_BeginRequest dealing with it on global.asax) on the live server, IIS bypasses my application and shows its own error page.
How can I disable IIS error handling and redirect where I want to?
I have introduced site wide exception handling on my site to catch unexpected errors. The event handler sends a message to me when such an exception occurs. But the problem is that any clicks on my site will cause an exception to be thrown with the message: "This is an invalid webresource request."
I googled for an answer and only found a couple of references to 1. setting a fixed machinekey (which for some reason didn't work for me, I got an error saying that the virtual directory wasn't set in IIS, and as far as I know I'm not using IIS at all, I'm using the local development environment and then deploy to a web host) or 2. using a robots.txt file to stop robots from accessing the axd files, but that doesn't help either because it's not robots that cause the problem, anyone clicking around on the page will cause this error. how to solve this problem properly? For now I have handled it by catching and ignoring this particular error by the text in the error message, which works but I would rather fix it so that this error doesn't occur at all.
how can i show the full blown .net exception that may occur on an ajax enabled page. i want it to show like it would if the page wasnt using ajax. This for my QA environment for which i dont have the option to temporarily disable update panel. Also i dont want javascript to handle it as our QA testers are wanting to see the usual full blown asp.net exception.
I have what is probably a basic question, but I am rather new to writing exception handling code. I thought I understood the concept, but apparently I don't, heres the code:
[Code]....
If I enter in any non-integer values, the textbox is set to nothing and the label displays the error message. However, now that I have verified the textbox contains an integer, I want to continue on and use that value. The remaining code works fine unless there was an exception, in which case the conversion to an int value for x throws an error.
All the examples I have looked at demos the structure of try-catch-finally, but in this instance I am not performing any clean up, I want to execute code when a valid value is entered into the textbox.
