two checkboxes mutually exclusive with the help of javascript in asp.net
Option 1: Why use Checkbox if so? Use RadioButtons (suggestible)
Option 2: If you really want to use checkbox, then try following:

JavaScript

<script type="text/javascript">  
      $(document).ready(function(){  
            //toggle all checkboxes in toggleContainer div  
            $('#toggleContainer :checkbox').bind('change',function(){  
                var thisClass=$(this).attr('class');  
                if($(this).attr('checked'))  
                {  
                    $('#toggleContainer :checkbox.'+thisClass+":not(#"+this.id+")").removeAttr('checked');      
                }  
                else  
                {  
                    $(this).attr('checked','checked');                            
                }  
            });  
        });  
    </script>

Above code snippet is mentioned in detail here: jQuery Mutually exclusive checkboxes in asp.net [^]

Option 3 & 4:
Refer: How can I make a group of checkboxes mutually exclusive?[^]
MS ASP.NET Creating Mutually Exclusive Checkboxes (C#)[^]

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

    <title></title>
    <script type="text/javascript">
        $(document).ready(function() {
            $("#chkbox input:checkbox").click(function() {               
                checkState = $(this).attr('checked');
                $('#chkbox input:checkbox').each(function() {
                    $(this).attr('checked', false);
                });
                $(this).attr('checked', true);
            });
        });      
    </script> 
</head>
<body>
    <form id="form1" runat="server">
    <div id="chkbox">
    <asp:CheckBox ID="CheckBox1" runat="server" />One<br />
        <asp:CheckBox ID="CheckBox2" runat="server" />Two<br />

The best solution is not to use a check box - use a radio button instead: http://www.w3schools.com/aspnet/control_radiobutton.asp[^]

Users are familiar with radio buttons being "one of these", but expect check boxes to allow multiple selections, not be mutually exclusive

JavaScript

<script language="javascript" type="text/javascript">
function CheckUncheck(chk1, chk2) {
var chkbox1 = document.getElementById(chk1);
var chkbox2 = document.getElementById(chk2);
chkbox2.checked = !chkbox1.checked;
}
</script>

ASP.NET

<asp:checkbox id="CheckBox1" runat="server" />
<asp:checkbox id="CheckBox2" runat="server" />

Here is the code behind:

C#

if (!IsPostBack)
{
CheckBox1.Attributes.Add("onclick", "CheckUncheck('" + CheckBox1.ClientID + "','" + CheckBox2.ClientID + "');");
CheckBox2.Attributes.Add("onclick", "CheckUncheck('" + CheckBox2.ClientID + "','" + CheckBox1.ClientID + "');");
}
