If we want to behave the checkbox as radio buttons we can use JS as shown below.
JS
function CheckOnce(checkbox) {
$("[id$='_chkLocations']").each(function (i, obj) {
if (obj !== checkbox) obj.checked = false
if (obj.checked) {
//do something
}
});
}
HTML
<input type="checkbox" ID="chkLocation" onclick="CheckOnce(this)">
<input type="checkbox" ID="chkLocation" onclick="CheckOnce(this)">
Cheers
