JQuery Validate RadioButtonList in Asp.Net Example

Sep 12, 2012
Introduction

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

Description:
  
In previous articles I explained
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 radiobuttonlist 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 runat="server">
<title>Validate asp.net radiobuttonlist 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() {
$('#btnSubmit').click(function() {
if ($('#rdbtnGender :radio:checked').length > 0) {
return true;
}
else {
alert('Please select Gender')
return false;
}
})
})

</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<table>
<tr>
<td> <b>Select Gender:</b></td>
<td>
<asp:RadioButtonList ID="rdbtnGender" runat="server" RepeatDirection="Horizontal">
<asp:ListItem Value="1" Text="Male" />
<asp:ListItem Value="2" Text="Female" />
</asp:RadioButtonList>
</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 radiobuttonlist using JQuery in asp.net.

$("#<%= Button1.ClientID %>").click(function () {


var groups = {}


$(":radio").each(function () {
groups[this.name] = true;
});


for (group in groups) {
var radioButttons = $(":radio[name=" + group + "]:checked");
isChecked = !!radioButttons.length;
if (!isChecked) {
$(":radio[name=" + group + "]").next("label").css("background-color", "blue");
}
else {
$(":radio[name=" + group + "]").next("label").css("background-color", "white");
}
}
return false;
});
