Validate DropdownList Using JQuery in Asp.Net

Sep 12, 2012

Here I will explain how to validate dropdownlist using
JQuery using

In previous articles I explained validate checkboxlist in JQuery, validate radiobuttonlist using JQuery,
validate email address using JQuery and many articles relating to JQuery. Now I will explain how to validate dropdownlist using JQuery in

To implement this one we need to write code as shown below in your aspx page

<html xmlns="">
<head id="Head1" runat="server">
<title>Validate Dropdownlist in JQuery</title>
<script type="text/javascript" src="">
<script type="text/javascript" language="javascript">
$(document).ready(function() {
$('#btnSubmit').click(function() {
if ($("#ddlCountry").val()>0) {
return true;
else {
alert('Please select Country')
return false;

<form id="form1" runat="server">
<td> <b>Select Country:</b></td>
<asp:DropDownList ID="ddlCountry" runat="server">
<asp:ListItem Text="Select" Value="0" />
<asp:ListItem Text="Australia" Value="1" />
<asp:ListItem Text="India" Value="2" />
<asp:ListItem Text="England" Value="3" />
<asp:ListItem Text="USA" Value="4" />
<asp:ListItem Text="China" Value="5" />
<asp:Button ID="btnSubmit" Text="Submit" runat="server" />
If you observe above code in header section I added script file link by using that file we have a chance to interact with JQuery and in the script we have btnSubmit button click function which is used to validate dropdownlist using JQuery in
