Description

When I try to load the Kendo UI Grid wrapper for React in Internet Explorer (IE), the component does not load and the Object doesn't support property or method 'assign' error appears in the console. How can I load the Grid in IE?

Possible Cause

The ShimJS library is not included in the page.

Solution

Include the ShimJS library by adding <script src="https://unpkg.com/core-js/client/shim.min.js"></script>.
