Hi,

Please find following Javascript functions to select / deselect checkbox using div (This will apply checkboxes in a div)

<script type="text/javascript">
function checkedall(divname) {
    $("#" + divname).find(':checkbox').each(function () {
        $(this).attr('checked', true);
    });
}

function uncheckedall(divname) {
    $("#" + divname).find(':checkbox').each(function () {
        $(this).attr('checked', false);
    });
}
</script>

You can all above functions like

<a href="javascript:void(0);" onclick="javascript:checkedall('div_nave');">Select All</a>

In short you can use following code for single checkbox using Id
$('#checkbox_id').attr('checked', true);

If you have any query, Please let me know.
Thanks,
Ajay
