Complete Example for Error Handlers Other Versions Visual Studio 2010 .NET Framework 4 Visual Studio 2008 This code example includes elements for both https://msdn.microsoft.com/en-us/library/bb397417.aspx page-level and application-level exception handling. Code Example Files The example consists of the following files: Web.config Global.asax Default.aspx ExceptionUtility (to be put in the App_Code folder) GenericErrorPage.aspx HttpErrorPage.aspx Http404ErrorPage.aspx DefaultRedirectErrorPage.aspx Web.config The following example shows the Web.config file. The customErrors section specifies how to handle errors that occur with file types that are mapped to ASP.NET, such as .aspx, .asmx, and .ashx files. (In IIS 6.0 and in IIS 7.0 in classic mode, static content files such as .html and .jpg files are not mapped to ASP.NET.) The settings in the example customErrors section cause any unhandled HTTP 404 (file not found) errors to be directed to the Http404ErrorPage.aspx file. These HTTP 404 errors would occur if a request were made for an .aspx file, .asmx file, and so on and if the requested file did not exist. All other unhandled errors in ASP.NET files are directed to the DefaultRedirectErrorPage.aspx file. If static content files are not handled by ASP.NET, a request for a nonexistent .html or .jpg file does not cause a redirect

Is some kind of global exception handler not enough? –driushkin Apr 2 '11 at 9:31 add a comment| 3 Answers 3 active oldest votes up vote 2 down vote Answering exactly to what you are asking, try-catch blocks are used to handle exceptions, so you should put them where you will actually be handling the exception. This can be a bit subtle, so let me put some example: imagine you have some method to do something with a file, and the path to the file is given as an argument. There may happen many bad things on that situation: If the file can't be found, or it can't be open (ex: permissions issues, blocked by some procoess, etc), then it's the caller's and not the callee's fault, and the exception produced is already a description of the problem: let it propagate.
