What are you trying to accomplish? At a guess I would say that you need to explore the creation of a base page where you have your exception handling and inherit your other pages from it. share|improve this answer answered Jan 12 '11 at 16:41 Oded♦ 340k54592785 Well I was hoping I could catch all exceptions that were unhandled on a page and show a message on the masterpage to the user –m.edmondson Jan 12 '11 at 16:46 @m.edmondson - do you mean you want to display the errors on the master page? –Oded♦ Jan 12 '11 at 16:50 No not the actual errors - just a generic message whilst e-mailing me the stacktrace etc –m.edmondson Jan 12 '11 at 16:52 @m.edmondson - Here is a good article that goes into master pages in depth. I feel you have some misconceptions about how they work. odetocode.com/code/450.aspx –O

Join them; it only takes a minute: Sign asp net 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 asp net error 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 avoid it. I'm allowed to write on the Response object. The response I received is something like: RESPONSE HEADER Response HTTP/1.1 200 OK Server ASP.NET Development Server/11.0.0.0 Date Fri, 10 Jan 2014 07:56:32 GMT X-AspNet-Version 4.0.30
