List Selection Button on Control Designer

I have a custom control designer and was trying to implement a button to select a list, as implemented in the built in list content. This may be rather simple, but I cannot for the life of me work it out, any help would be appreciated.

Hello Whitehawksan,

I suggest referring to this blog post if you encounter a problem implementing functionality with the control designer.
Place the checkboxes on the designer similar to:
<form id ="form1">
<input type="checkbox" name="check1">
<input type="checkbox" name="checkk2">
</form>
 
//the checkbox that will select them all calls a function
<input type='checkbox' name='checkall' onclick='checkedAll(frm1);'>
<script type="text/javascript">
checked=false;
function checkedAll (frm1)
    var aa= document.getElementById('form1');
     if (checked == false)
          
           checked = true
          
        else
          
          checked = false
          
    for (var i =0; i < aa.elements.length; i++)
    
     aa.elements[i].checked = checked;
    
      
</script>
