I have added a URL field to the Sales Order Details tab and it works correctly
Is there a way i can hide the URL itself as some of them will be very long and instead just display an image or the word URL in the column so the column width can be kept small. If the user clicks on this then it will take them to the embedded URL
I have seen it done in GI, Navigation Configuration: To Configure Navigation to an External URI
but not sure how to configure for detail grid. maybe I will learn today 
Hi
You can try using the PXRedirectToUrlException within the field selecting event.
Example,
throw new PXRedirectToUrlException(redirectUrl, PXBaseRedirectException.WindowMode.New, string.Empty);
