    Hi There,

    I have come back to a system I coded 2 years ago. The code worked fine when I last worked on the web app but now I am getting the attached errors.

    Does anyone have any ideas why I'm getting these errors.


    Thanks for your help.


    Best Regards,

    Hi Steve,

    The Visual Studio info message is shown because the RadMenuItem does not have a property named id. As Visual Studio detects that, it shows the message. 

    You can find another forum thread on the topic at Not a valid attribute of element RadTab message and especially this reply: https://www.telerik.com/forums/not-a-valid-attribute-of-element-radtab-message#jkVBz3yqmE26RwPg6vPIzA.

    Best regards,
