Example to implement Jquery form validations in asp.net C#,Vb.net

IntroductionIn previous articles i explained JavaScript validation in asp.net website and  How to show Validation guidelines in web forms using JavaScript in Asp.net and Drag & drop to upload multiple files using AjaxFileUpload like Facebook and How to upload file and create Zip file in asp.net using C#,VB.Net and Bind and Export GridView data to PDF file in asp.net and Get Title,Description and Keywords Meta tags from URL in asp.net.
 In this article I am going to implement validations using Jquery. We can also implement validations through validation controls provided by asp.net .You can read my articles on validation controls in asp.net.but in this example I have used Jquery.

 I have created a web form having all the basic fields and implemented the necessary and recommended validations on each field as describes below:
  • Validation implemented on each field is explained as:
Name: can’t be left blank.

User Name: can’t be left blank and should be at least 5 characters long.

Email Id: can’t be left blank and should be in valid email format.

Password: can’t be left blank and should be between 6 - 10 characters.

Confirm Password: can’t be left blank and should be between 6 - 10 characters and must 
match with the Password field.

Website: can’t be left blank and should be in valid URL format e.g. http://www.webcodeexpert.com

Age: can’t be left blank and should be digits and between 20 - 25.

DOB: can’t be left blank and should be valid date format (mm/dd/yyyy)

Mobile No.: can’t be left blank and should be digits and 10 digits long.

Address: can’t be left blank.

Zip Code: can’t be left blank and should be digits and at least 6 digits long.

Hobbies: at least one hobby should be checked

In the <Head> tag of the design page (.aspx) add the following 

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" type="text/javascript"></script>
        <script src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.9/jquery.validate.min.js" type="text/javascript"></script>

                        "Missing required status - Must choose one");

            $.validator.setDefaults({ ignore: [] });

                </tr>
            </table>
        </fieldset>
  • Create a style sheet to add styles to the form created:
Go to Website menu ->Add New Item ->Select StyleSheet -> Ok.
It will add a StyleSheet.css under your website project in solution explorer. Open the StyleSheet.css and add the following

body {
}

#field{margin-left: .5em;float: right;}

#field, label{float: left;font-family: Arial, Helvetica, sans-serif;font-size: small;}
div{height:17px;}
br{clear: both;}

input{border: 1px solid black;margin-bottom: .5em;}

input.error{border: 1px solid red;}

label.error{position:static;background: url('Images/wrong.png') no-repeat;padding-left: 20px; margin-left: .3em; vertical-align: middle;background-color: #FFEBE8;width: 250px;float:right;}

label.valid{position:inherit;background: url('Images/right.png') no-repeat;display: block; float:right; margin-right:235px; width: 16px;height: 16px;border: none;vertical-align:top;}

.clr{clear:both}
.lblsize{float:left; width:150px;}
.inpsize{float:left; width:200px; margin-right:10px;}
.fldsize{width:640px;}

Also create a folder in the root directory and name it “Images”. Search on Google the images for “tick(right.png in our example)” and “cross(wrong.png in our example)” to show while validation success and failure as in my example

Hello deepak..thanks for notifying the problem..i have re-checked and resolved the error and updated the article..You just need to set debug: false instead of debug: true.

Stay tuned and stay connected for more updates
