                               <input id="Checkbox6" type="checkbox"  value="Show Deleted" style=" color: Black" class="chkdisplay"/><span style=" color: Black" >Show Deleted</span><br />
                               <input id="Checkbox7" type="checkbox"  value="Treated" style=" color: Black" class="chkdisplay"/><span style=" color: Black" >Treated</span><br />

Script i used(not working)
$('.chkdisplay').on('change blur', function () {
$('#Alloption').prop('checked', !($('.chkdisplay').not(':checked').length));
});

I want to iterate the checkboxes from 1 to 7 and if any of this checkbox is checked the uncheck checkbox with id="All"

Add an common change event handler to all 7 checkboxes, check if any of the checkboxes are checked

HTML

<input id="Checkbox2" type="checkbox"  value="Accepted"  style=" color: Black"  class="chkdisplay" onchange="toggleAllCb(this)" /><span style=" color: Black" >Accepted </span><br />
                               <input id="Checkbox3" type="checkbox" value="Contracted" style=" color: Black" class="chkdisplay" onchange="toggleAllCb(this)"/><span style=" color: Black" >Contracted</span><br />
                               <input id="Checkbox4" type="checkbox"  value="Pending" style=" color: Black" class="chkdisplay" onchange="toggleAllCb(this)"/><span style=" color: Black" >Pending</span><br />
                               <input id="Checkbox5" type="checkbox"  value="Pre-Authorized" style=" color: Black" class="chkdisplay" onchange="toggleAllCb(this)"/><span style=" color: Black" >Pre-Authorized</span><br />
                               <input id="Checkbox6" type="checkbox"  value="Show Deleted" style=" color: Black" class="chkdisplay" onchange="toggleAllCb(this)"/><span style=" color: Black" >Show Deleted</span><br />
                               <input id="Checkbox7" type="checkbox"  value="Treated" style=" color: Black" class="chkdisplay" onchange="toggleAllCb(this)"/><span style=" color: Black" >Treated</span><br />

And in your script

JavaScript

function toggleAllCb(sender)
{
   if($("#Alloption").checked) {
      if(sender.checked)
         $("#Alloption").checked = false;
    }
}
