Hi,

I have downloaded the zip file from telerik(ProgressĀ® TelerikĀ® UI for ASP.NET MVC) site and used in my project. I have licensed version of telerik. I applied license in below approaches
1. Downloaded the key license .txt file and placed in the root folder of project and also added in system variables.
2. Downloaded the script license and placed in the project scripts, refereed in _layout.cshtml page.

Either of the approaches I am getting a warning  message at the top of my application while running the application.

message: both paid and trial usage. Learn how to set up a license key.

Please guide me how to setup license if I am missing something here.

Hello Ashok,

 

Thank you for reaching out.

This issue usually happens when the scripts are loaded multiple times. Please ensure that your Partial Views have the Layout=null as explained and demonstrated here:

Let me know if the information and steps provided in the post are helpful.
