Asp Net Error Handling Best Practices
Us Ask a Question All Questions All Unanswered FAQ The best way to handle exceptions in a Masterpage setup Rate this: Please Sign up or sign in to vote. See more: C# ASP.NET Masterpage , + I have a website where I want to pass an error code to the user so that QA can look back at the error and figure out what happened. I want to do this without displaying specific error details like the exception message or stack trace to the end user. I wrote the below method that sits inside of the top-level master page for the site and I'm wondering what the best way to call it is if any exception is raised in the application. The only way to do so that I have thought up of so far is too create try catch blocks in every method in the project but I don't really want to do that. public void ExceptionHandler(Exception e) { string s = Guid.NewGuid().ToString(); try { throw new Exception(s, e); } catch (Exception ex) { throw ex; } finally { divException.InnerHtml = "An exception has occured, please contact QA for more info.\n Error Code: " + s; } } And if, I'm doing this the completely wrong way from the first place feel free to suggest other solutions.

Join them; it only takes a minute: Sign up Exception Handling on the OnError method of the Master Page in ASP.NET up vote 1 down vote favorite I'm having a problem related to the error handling when overriding the OnError method. In my project I have 10 pages deriving from BasePage and using all the same MasterPage. Actually I have this structure: MyPage : BasePage ==> Generates Exception In BasePage: protected override void OnError(EventArgs e) //Get all the errors from derived pages { var error = Server.GetLastError(); Server.ClearError(); PMIMaster.HandleError(error); } In Master Page: internal void HandleError(Exception e) //Show the error in a particular label { AlertMessageHandler.DisplayMessage(exc.Message); } The AlertMessageHandler.DisplayMessage(string) simply edit a label and put it visible. Where is the problem? If I call the "AlertMessageHandler.DisplayMessage(string)" from code (without the generation of exception) everything works fine. If I throw a new Exception if doesn't work as expected: it goes to the BasePage, it reaches the Master and the method exposed... But in the end I have no result. How can I handle it? --- EDIT --- I've done some more research. Actually, even if I clear the exception, during the response the javascript find the same exception (even if it is cleared from serverside). The exception is raised on the method: Sys$WebForms$PageRequestManager$_endPostBack(error, executor, data) And I cannot find a way to avo
