crm 2015 unsupported line of code - HTML Resource : I just did an upgrade from CRM 2011 to CRM 2015. I was just wondering if the below line of code is supported in CRM 2015. This piece of code is in a HTML resource.
document.getElementById('crmGrid').parentElement.innerHTML=document.frames['grid'].document.getElementById('crmGrid').parentElement.innerHTML;

Thanks in advance.
