Symptoms

Loading kendo.all.min.js file in IE 8 results in multiple JavaScript errors.

Typically the error message will be "Object doesn't support this property or method" and will be caused by a call to mapforEach or bind.

Root Cause

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.

Mitigation

  • Use a custom bundle that does not include the Spreadsheet widget
  • Load an ES5 Polyfill, for example es5-shim, before kendo.all.min.js:

 

 

Solution

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.​
