DatePicker not opening IE7, IE8 in iframe (access is denied)

[David Forehand]

I am having a problem with the DatePicker. It is not opening properly in IE7 or IE8 when accessed via an iframe. It works fine when it's not accessed via an iframe. The Javascript error I am getting is below.

This problem does not happen in Chrome or Firefox. 

When using Telerik version 2008.2.286.20, it only happened on IE7 and did not happen on IE8. 

After upgrading to version 2009.3.1103, it not happens on IE7 and IE8.

Has anyone ever seen this before?

Hi David,

The error is caused by the Sys.UI.DomElement.getLocation method, which is part of the MS Ajax client framework. You options are:

1) the main page and the iframe page should be in the same domain
or
2) implement the workaround suggested here
