I have CRM 2013 environment with IFrame set up in account entity. IFrame has external ASP.NET Application which uses JQeury.blockUI.JS to block all the UI until everything loads up.
for some reason, blockUI doesn't display on IFrame and could not able to display Loading/progress message. Did any one tried this approach from iframe??
$('formDiv').block({ message: '<h3>Loading.....</h3>', css: { border: '3px solid #a00' } });
$('formDiv').unblock();
please assist.
