I copied the js and styles folders from Program Files (x86)\Progress\Telerik UI for ASP.NET Core R2 2018 to the \wwwroot\lib\kendo-ui\ folder on my project, cleaned my project, recompiled and ran the project and still get the same error. I then opened it in the browser being used by Visual Studio and also Chrome to verify it wasn't a browser issue, but the null still shows up.
Below is the code for the grid - Please advise.
