JQuery form validations example in

Jan 12, 2012

In this article I will explain how to show small popup or beautiful style of validation messages or inline form validation messages when validation fails in using JQuery.

In previous articles I explained about
Display validation error messages with images and Change textbox background when validation fails and Ajax Password Strength using  and many articles on JQUery. Now I will explain how to implement inline form validations when validation fails using JQuery in

In one of the website I saw different type of form validations in registration form when we click on submit button without entering any data they are showing some small balloon type validation messages we can implement this functionality easily by using available JQuery plugins.
First open Visual Studio and create new website after that right click on your website and add new folder and give name as JS and insert script files in folder you should get it from attached folder same way add another new folder and give name as CSS and insert required css files in folder you should get it from attached folder. After that write the following code in your aspx page 

<html xmlns="">
<head runat="server">
<title>Show Inline validation Messages</title>
<link href="css/template.css" rel="stylesheet" type="text/css" />
<link href="css/validationEngine.jquery.css" rel="stylesheet" type="text/css" />
<script src="js/jquery-1.6.min.js" type="text/javascript"></script>
<script src="js/jquery.validationEngine-en.js" type="text/javascript" charset="utf-8"></script>
<script src="js/jquery.validationEngine.js" type="text/javascript" charset="utf-8"></script>
<script type="text/javascript">
jQuery(document).ready(function() {
<form id="form1" runat="server">
<table align="center">
<td colspan="2">
<div style="border: 1px solid #CCCCCC; padding: 10px;">
<table cellpadding="0" cellspacing="30" style=" background-color:White">
<td>First Name:</td>
<td><asp:TextBox ID="txtfname"  runat="server" CssClass="validate[required]"/></td>
<td>Last Name:</td>
<td><asp:TextBox ID="txtlname"  runat="server" CssClass="validate[required]"/></td>
<tr >
<td><asp:TextBox ID="txtemail" runat="server"  CssClass="validate[required,custom[email]" />
<tr >
<td><asp:TextBox ID="txtUrl" runat="server" CssClass="validate[required,custom[url]] text-input" />
<td valign="top">Address:</td>
<asp:TextBox ID="txtaddress" runat="server" TextMode="MultiLine" Rows="8" Columns="26"/></td>
<asp:DropDownList ID="ddlState" runat="server" CssClass="validate[required] radio">
<asp:ListItem value="">Choose State</asp:ListItem>
<asp:ListItem Value="AL">Alabama</asp:ListItem>
<asp:ListItem value="AK">Alaska</asp:ListItem>
<asp:ListItem  value="AL">Alabama </asp:ListItem>
<asp:ListItem  value="AK">Alaska</asp:ListItem>
<asp:ListItem  value="AZ">Arizona</asp:ListItem>
<asp:ListItem  value="AR">Arkansas</asp:ListItem>
<asp:ListItem  value="CA">California</asp:ListItem>
<asp:ListItem  value="CO">Colorado</asp:ListItem>
<asp:ListItem  value="CT">Connecticut</asp:ListItem>
<asp:ListItem  value="DE">Delaware</asp:ListItem>
<asp:ListItem  value="FL">Florida</asp:ListItem>
<asp:ListItem  value="GA">Georgia</asp:ListItem>
<asp:ListItem  value="HI">Hawaii</asp:ListItem>
<asp:ListItem  value="ID">Idaho</asp:ListItem>
<asp:TextBox ID="txtZip" runat="server" CssClass="validate[required,custom[integer]] text-input"/>
<td> I Agree Conditions</td>
<input class="validate[required] checkbox" type="checkbox" id="agree" name="agree"/>
<asp:Button ID="btnSubmit" runat="server" Text="Submit" onclick="btnSubmit_Click" />
<td colspan="2">
<asp:Label ID="lblResult" runat="server" Font-Bold="true"/>
If you observe above code in header section I added some of script files and css files by using those files we have a chance to show popup messages when validation fails using JQuery in Here one thing we need to remember that is if we want add validation for particular control then we need to add css class CssClass="validate[required]" to that particular control.

Now add the following namespaces in code behind

using System;
using System.Drawing;
After that add following codes in code behind

protected void btnSubmit_Click(object sender, EventArgs e)
lblResult.Visible = true;
lblResult.Text = "Successfully Validated all the controls";
lblResult.ForeColor = Color.Green;
After run your application and check the output.


Download sample code attached

Here we can customize the script files based on our requirement and if we have more fields automatically scroll the page to first error. If you observe above demo in that ZiP Code field allows only numbers, Url field allows only valid url format and Email field allows only certain email format in the same way we have different options like date, maximum numbers allowed etc based on our settings in script file .

I was wondering if u could tell me how to use this within a content page.. When I use the form tag inside a content page it throws the following exception "System.Web.HttpException: A page can have only one server-side Form tag".
Is there any way to work around this?
Thankyou. .

Anonymous said...

I used it this is a great tools but i find it hard to fix certain thing, Like it validation triggers for MasterPage design for any button on the master page on content page.
How can we get around that.

Second i had integrated same validation with 3 Ajax Modal popups in one page as requirement was such in such scenario sometimes button doesnt fire and other similar issue. Anyway Just was to thank you who have put some real good article which are worth using

Zaheer said...


I want to ask you one simple question. I have checked it. It only works with button whose type=submit. How we can use it with type=button. I have checked it but it doesn't work.

Suresh Dasari said...

If you observe above post in that i used asp control with type=button not type=submit please check it once it's working fine.

How we can set causevalidation="false" property of this button.. Using these validations

M.K.Balachandran said...

In my form 2 buttons are there one is submit and another one is cancel. when user press cancel button that time also validation has come so how to solve this?

Jeremy said...

Thanks for this! It does work as advertised; however, it does not seem to pass a validation check even though the form seems to work.

Also, In my scenario my form resides on a masterpage and that seems to break it. I have looked around and so far this is the best post I have seen in a hundred, but it doesn't cover this. Any help would be GREATLY apprecieated! Thanks!

Jeremy said...

This works great, best example I have seen and I REALLY looked! However, as soon as I try to use this in scenario where my form resides on a masterpage, and your provided table resides on the childpage it breaks it. The table renders fine, but the validation fails; actually running alert($("#form1").validationEngine('validate')); returns false even without altering your code. Any help you could give me would be MUCH appreciated! Thanks again!

Zulfi said...

Hi Chetan I did the same thing and it was not working.
To work around after running your application just view the source of the page from the browser and check id of form what it is coming. Use that form id in your code and it will work perfectly.
Usually it is aspnetform

If i am validating the email field and the textbox has not any value then how can i only show the required field validation message.

Currently it's showing required field message as well as the url validation messgae at a time.

Hi Friends,
those people are facing the issue of Jquery validation fail while using Master Page. they search the form id in source page after running the project. In Source Page whatever Form ID is being made, Copy the Form ID and Paste inside the jquery document.get ready function in master page or any page which uses master page. after giving the right Form ID to the Jquery validationEngine() function, the Jquery velidation will start working. If still you face same problem. you can send me request mail at my EmailID i.e, i will send you test solution.

Hi suresh, Your articles are really worth,
Have big query in when we are using master page so id of control of content page would be something like "ContentPlaceHolder1_txtfnm" so validation is based on id of control and is gonna check the id which is only txtfnm so my question is how to fix or how validation checks the id=ContentPlaceHolder1_txtfnm,

Let me clear you that i have server controls used in master page as well so form tag is required at master page only....

Thanks in advance
