How to avoid the exception "does not contain a definition for 'EJ' and no extension method 'EJ'"?

Platform: ASP.NET MVC |
Control: General |
Published Date: June 12, 2015 |

Problem

While rendering Syncfusion controls, the following error is obtained - “Does not contain a definition for 'EJ' and no extension method 'EJ'”

Reason

When EJ namespace is not referred properly in the sample, EJ Undefined error is occurred.

Solution

To resolve this issue, add the following namespace code example to web.config file.

web.config

<pages>

    <namespaces>

      <add namespace="Syncfusion.JavaScript"/>

      <add namespace="Syncfusion.MVC.EJ"/>

    </namespaces>

</pages>

 

Note:

You need to add the above namespace in the root web.config file present in the application and another web.config file present in the Application -> Views Folder -> web.config file.
