Typically the error message will be "Object doesn't support this property or method" and will be caused by a call to map, forEach or bind.
The errors are due to the inclusion of the Kendo UI Spreadsheet which requires IE9 and later.
It was nevertheless bundled in kendo.all without the necessary run-time checks.
- Use a custom bundle that does not include the Spreadsheet widget
- Load an ES5 Polyfill, for example es5-shim, before kendo.all.min.js:
<!--[if lt IE 9]>
A permanent fix will be included in the next internal build, version 2015.3.1002, due for release on 2 Oct 2015.
Future Service Packs and official releases will be free of this defect as well.
Apologies for the caused inconvenience.
