I have a post here to show code examples for check/uncheck all checkbox with Jquery. This time I will implement another request that the user should only be able to check at most one of the checkboxes, it's behave like radio buttons. There are 2 cases. Case 1 shows function that has little difference with radio button. It allows the user to deselect checkbox. Case 2 is same as radio button. Case 1 <head id="Head1" runat="server">
<title></title>
<script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>
<style type="text/css">
.cbRowItem {display:block;}
</style>
<script type="text/javascript">
$(document).ready(function()
{
var $chk = $('input:checkbox .cbRowItem');
$chk.click(function()
{
$chk.not(this).removeAttr('checked');
});
});
</script>
</head>
<body>
<form id="form1" runat="server">
<div style="display:block;">
<asp:CheckBox id="CheckBox1" runat="server" class="cbRowItem"
Text = "CheckBox 1"/>
<asp:CheckBox id="CheckBox2" runat="server" class="cbRowItem"
Text = "CheckBox 2"/>
<asp:CheckBox id="CheckBox3" runat="server" class="cbRowItem"
Text = "CheckBox 3"/>
<asp:CheckBox id="CheckBox4" runat="server" class="cbRowItem"
Text = "CheckBox 4"/>
</div>
</form>
</body>
</html>
Case 2
<head id="Head1" runat="server">
<title></title>
<script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>
<style type="text/css">
.cbRowItem {display:block;}

$(document).ready(function()
{
var $chk = $('input:checkbox .cbRowItem');
$chk.click(function()
{
$chk.removeAttr('checked');
$(this).attr('checked', 'checked');
});
});
</script>
</head>
<body>
<form id="form1" runat="server">

<asp:CheckBox id="CheckBox1" runat="server" class="cbRowItem"
