Hello,

I'm working with ASP.NET 1.1. In my page I have a asp:checkbox.
Therefore a have this code in wich I want to enable and disable an 
asp:imagebutton.
It works fine for me when I want to disable the button, but when I deselect 
the check the button is not enabled again.
Did I do something wrong?

 function ApplyCortesy()
    {
      var ObjCheck = document.getElementById('chkTBFCOR');

         if (!ObjCheck.checked)
        {
             document.getElementById('btnGeneraMontos').disabled = 'false';
        }
        else
        {
             document.getElementById('btnGeneraMontos').disabled = 'true';
        }
}

Thanks
