jQuery Show Asp.Net Exception Error Message in AJAX Call Error Function in C#.Net VB.Net

May 17, 2015

Here I will explain how to show exception error message in jQuery ajax web method calls using error function in c#, or get error message in jQuery ajax post method in using c#, with example or jQuery show custom error message during ajax calls in using c#,

Now create one new web application and open your aspx page and write the code like as shown below

<html xmlns="">
<head runat="server">
<title>jQuery Get Original Exception Message in Ajax Method</title>
<script type="text/javascript" src=""></script>
<script type="text/javascript">
$(function () {
$('#btnSum').click(function () {
var val1 = $.trim($('#txtVal1').val());
var val2 = $.trim($('#txtVal2').val());
type: "POST",
url: "GetExceptionMessageinjQuery.aspx/GetSumofNumbers",
data: "{'val1':'" + val1 + "', 'val2':'" + val2 + "'}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (response) {
error: function (data) {
var r = jQuery.parseJSON(data.responseText);
var errorMessage = r.Message;
var exceptionType = r.ExceptionType;
var stackTrace = r.StackTrace;
$('#divStatus').html("<b>Error Message: </b>" + errorMessage + "</br></br>" + "<b>ExceptionType: </b>" + exceptionType + "</br></br>" + "<b>Asp.Net StackTrace: </b>" + stackTrace)
return false;
<form id="form1" runat="server">
<tr><td>First Number:</td><td><input type="text" id="txtVal1" /></td></tr>
<tr><td>Second Number:</td><td><input type="text" id="txtVal2" /> </td></tr>
<tr><td>SUM:</td><td><label id="lblMessage"/></td></tr>
<tr><td colspan="2"><input type="button" id="btnSum" value="Get Sum" /></td></tr>
<hr />
<div id="divStatus"></div>

Now open aspx page codebehind behind file and add following namespaces

C# Code

using System;
using System.Web.Services;

After completion of adding namespaces you need to write the code like as shown below

protected void Page_Load(object sender, EventArgs e)

public static int GetSumofNumbers(int val1, int val2)
return val1 + val2;


Imports System.Web.Services
Partial Class VBCode
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)

End Sub
<WebMethod()> _
Public Shared Function GetSumofNumbers(ByVal val1 As Integer, ByVal val2 As Integer) As Integer
Return val1 + val2
End Function
End Class
