Hi Rob,
I have noticed that this is a duplicate of another forum thread of yours. It is recommended to avoid submitting duplicate tickets as this would result in difficult navigation through your history. Check out the suggestion posted there:
https://www.telerik.com/forums/url-action-in-column-template-9796c608516c
It is important to add that if you would like to use the value of another field, you would have to simply pass the name of the field inside the "#=#" kendo template.
Best regards,
Tsvetomir
