Description:
In previous articles I explained about Display validation error messages with images and Change textbox background when validation fails and Ajax Password Strength using asp.net . Now I will explain how to highlight form controls when validation fails using JQuery in asp.net.
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 highlighting controls and changing the background color of controls. 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. After that write the following code in your aspx page
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title>Highlight page controls when validation fails in asp.net</title> <script src="JS/jquery.js" type="text/javascript"></script> <script src="JS/jquery.validate.js" type="text/javascript"></script> <script type="text/javascript" src="JS/jquery.maskedinput.js"></script> <script type="text/javascript" src="JS/mktSignup.js"></script> <link rel="stylesheet" type="text/css" media="screen" href="stylesheet.css" /> </head> <body> <div> <form runat="server" > <table cellpadding="0" cellspacing="0" border="0" align="center"> <h2>Billing Information</h2> <tr class="subTable"> <td colspan="2"> <div style="background-color: #EEEEEE; border: 1px solid #CCCCCC; padding: 10px;" class="subTableDiv"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="label">First Name:</td> <td class="field"><asp:TextBox ID="firstname" CssClass="ValidationRequired" runat="server"/></td> </tr> <tr> <td class="label">Last Name:</td> <td class="field"><asp:TextBox ID="lastname" CssClass="ValidationRequired" runat="server"/></td> </tr> <tr> <td class="label">Email:</td> <td class="field"><asp:TextBox ID="email" runat="server" CssClass="ValidationRequired email"/> <div class="formError"></div> </td> </tr> <tr> <td class="label">Address:</td> <td class="field"><asp:TextBox ID="bill_address1" runat="server" CssClass="ValidationRequired"/></td> </tr> <tr> <td class="label"></td> <td class="field"><asp:TextBox ID="bill_address2" runat="server" CssClass="ValidationRequired"/></td> </tr> <tr> <td class="label">City:</td> <td class="field"><asp:TextBox ID="bill_city" runat="server" CssClass="ValidationRequired"/></td> </tr> <tr> <td class="label">State:</td> <td class="field"> <asp:DropDownList ID="ddlState" runat="server" CssClass="ValidationRequired"> <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:DropDownList> </td> </tr> <tr> <td class="label">Zip:</td> <td class="field"> <asp:TextBox ID="txtZip" runat="server" CssClass="ValidationRequired zipcode"/> </td> </tr> <tr> <td class="label">Phone:</td> <td class="field"> <asp:TextBox ID="txtPhone" runat="server" CssClass="ValidationRequired phone"/> </td> </tr> <tr> <td class="label">Credit Card Type:</td> <td class="field"> <asp:DropDownList ID="ddlCardType" runat="server" CssClass="ValidationRequired"> <asp:ListItem Value="">Choose Credit Card</asp:ListItem> <asp:ListItem value="amex">American Express</asp:ListItem> <asp:ListItem value="discover">Discover</asp:ListItem> <asp:ListItem value="mastercard">MasterCard</asp:ListItem> <asp:ListItem value="visa">Visa</asp:ListItem> </asp:DropDownList> </td> </tr> <tr> <td class="label">Expiration:</td> <td class="field"> <asp:DropDownList ID="ddlExpMonth" runat="server"> <asp:ListItem value="01">Jan</asp:ListItem> <asp:ListItem value="02">Feb</asp:ListItem> <asp:ListItem value="03">Mar</asp:ListItem> <asp:ListItem value="04">Apr</asp:ListItem> <asp:ListItem value="05">May</asp:ListItem> <asp:ListItem value="06">Jun</asp:ListItem> <asp:ListItem value="07">Jul</asp:ListItem> <asp:ListItem value="08">Aug</asp:ListItem> <asp:ListItem value="09">Sep</asp:ListItem> <asp:ListItem value="10">Oct</asp:ListItem> <asp:ListItem value="11">Nov</asp:ListItem> <asp:ListItem value="12">Dec</asp:ListItem> </asp:DropDownList> <asp:DropDownList ID="ddlExpYear" runat="server"> <asp:ListItem value="2007">2007</asp:ListItem> <asp:ListItem value="2008" Selected="True">2008</asp:ListItem> <asp:ListItem value="2009">2009</asp:ListItem> <asp:ListItem value="2010">2010</asp:ListItem> <asp:ListItem value="2011">2011</asp:ListItem> <asp:ListItem value="2012">2012</asp:ListItem> <asp:ListItem value="2013">2013</asp:ListItem> <asp:ListItem value="2014">2014</asp:ListItem> <asp:ListItem value="2015">2015</asp:ListItem> <asp:ListItem value="2016">2016</asp:ListItem> </asp:DropDownList> </td> </tr> <tr> <td class="label">Credit Card Number:</td> <td class="field"> <asp:TextBox ID="creditcard" runat="server" CssClass="ValidationRequired" MaxLength="40"/> </td> </tr> <tr> <td class="label"><label for="cc_cvv">Security Code:</label></td> <td class="field"> <asp:TextBox ID="txtccNumber" runat="server" CssClass="ValidationRequired" MaxLength="4" style="width: 30px;"/> </td> </tr> <tr> <td></td> <td> <div class="buttonSubmit"> <span></span> <asp:Button ID="btnSubmit" runat="server" Text="Submit" CssClass="formButton" onclick="btnSubmit_Click" /> </div><br clear="all"/> </td> </tr> <tr> <td colspan="2"> <asp:Label ID="lblResult" runat="server" Font-Bold="true"/></td> </tr> </table> </div> </td> </tr> </table> <div> </div> </form> </div> </body> </html> |
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 highlight controls when validation fails using JQuery in asp.net. 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="ValidationRequired" to that particular control.
Now add following code 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 if you observe above demo in that ZiP Code , Phone Number and Credit Card Number fields are allowing only numbers in particular format based on our settings in our script file.
