Hi Pratheep,

Thanks for using Syncfusion products.

We have analyzed the provided sample and found that the issue is due to the missing reference of the Syncfusion.JavaScript.Models namespace in the page. The ej:Columns is available in Syncfusion.JavaScript.Models  namespace from Syncfusion.EJ assembly. And so please add the below line either in your ASPX page or web.config to resolve this issue.

ASPX

   <%@ Register Assembly="Syncfusion.EJ, Version=13.1400.0.21, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89"

    Namespace="Syncfusion.JavaScript.Models" TagPrefix="ej" %>

And also we need to include several script/CSS files to render with Essential ASP.Net controls, please refer the below table.

Script files	Syncfusion script files: ej.web.all.min.js ej.unobtrusive.min.js External Script files: Jquery.min.js Jquery.easing.min.js Jquery.globalize.min.js Jsrender.min.js Jquery.validate.min.js
CSS files	ej.widgets.all.min.css

You can find the script and CSS files from the below location after installing Essential Studio.

Scripts and Css: C:\Program Files (x86)\Syncfusion\Essential Studio\XX.X.X.XX\JavaScript\assets

Where XX.X.X.XX denotes the product version

For your convenience we have modified your sample and the same can be downloaded from the below location.
