This is an example of what a call might look like: $.ajax({ url: "userCreation.ashx", data: { u:userName, p:password, e:email }, type: "POST", beforeSend: function(){disableSubmitButton();}, complete: function(){enableSubmitButton();}, error: function(xhr, statusText, errorThrown){ // Work out what the error was and display the appropriate message }, success: function(data){ displayUserCreatedMessage(); refreshUserList(); http://stackoverflow.com/questions/28529/how-would-you-handle-errors-when-using-jquery-ajax } }); The request might fail for a number of reasons, such as duplicate user name, duplicate email address etc, and the ashx is written to throw an exception when this happens. My problem seems to be that by throwing an exception the ashx causes the statusText and errorThrown to be undefined. I can get to the XMLHttpRequest.responseText which contains the HTML that makes up the standard .net error page. I am finding the page title in the responseText and using the title to work out which error was thrown. Although I have a suspicion that this will fall apart when I enable custom error handling pages. Should I be throwing the errors in the ashx, or should I be returning a status code as part of the data returned by the call to userCreation.ashx, then using this to decide what action to take? How do you handle these situations? asp.net jquery ajax share|improve this question edited Aug 26 '08 at 16:44 travis 20.6k175585 asked Aug 26 '08 at 16:26 AidenMontgomery 1,25711523 add a comment| 3 Answers 3 active oldest votes up vote 15 down vote accepted Should I be throwing the errors in the ashx, or should I be returning a stat
