jQuery Validate CheckBoxList in Asp.Net Example

Sep 12, 2012
Introduction

Here I will explain how to validate checkboxlist using
JQuery using asp.net.

Description:
  
In previous articles I explained validate radiobuttonlist using JQuery,
validate email address using JQuery, how to disable or enable all the controls on page using JQuery , validate phone number using JQuery and many articles relating to JQuery. Now I will explain how to validate checkboxlist using JQuery in asp.net.

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


<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title>Validate asp.net Checkboxlist in JQuery</title>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js">
</script>
<script type="text/javascript" language="javascript">
$(document).ready(function() {
$('#btnSubmit').click(function() {
if ($('#chktech input:checked').length > 0) {
return true;
}
else {
alert('Please select atleast one technology')
return false;
}
})
});

</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<table>
<tr>
<td> <b>Select Technologies:</b></td>
<td>
<asp:CheckBoxList ID="chktech" runat="server" >
<asp:ListItem Value="1" Text="Asp.net" />
<asp:ListItem Value="2" Text="C#.NET" />
<asp:ListItem Value="3" Text="JQuery" />
<asp:ListItem Value="4" Text="JavaScript" />
<asp:ListItem Value="5" Text="SQL Server" />
</asp:CheckBoxList>
</td>
</tr>
<tr>
<td></td>
<td>
<asp:Button ID="btnSubmit" Text="Submit" runat="server" />
</td>
</tr>
</table>
</div>
</form>
</body>
</html>

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 checkboxlist using JQuery in asp.net.
