Datepicker failing inside an iframe v2012.3.1315

[Kelly]

We have a datepicker on an MVC view, rendered per this snippet:

@(Html.Kendo().DatePicker()

  .Name("criteriaDate")

  .Depth(CalendarView.Year)

  .Format(Model.DateFormat)

  .Max(Model.RangeEnd.DateTime)

  .Min(Model.RangeStart.DateTime)

  .Value(Model.RangeStart.DateTime)

  .HtmlAttributes(new { style = "width:100%;" })

)

Everything works fine when the view is rendered directly, but when another site attempts to show it in an iframe we are seeing this error in the Visual Studio debugger: Unhandled exception at line 25, column 9190 in http://localhost/site/Scripts/kendo.all.min.js, which is in the toFront function on the "s=document.activeElement" line. The result is that the datepicker control doesn't render on the page.

I didn't see anything on this topic, so any help would be appreciated. Thanks in advance...

Hello Paul,

This is a known problem in Internet Explorer when document.activeElement is referenced from within an iframe. The problem has been recently detected and fixed, and changes will take effect in the next internal and official builds
