Indeed the RadDataForm does not support Custom editors at this very momenт. The good news is that the implementation for the custom editors in Angular is already in the final stage and needs to be tested and documented and will be part of our next release. The release is expected approximately at the end of this month or earlier.
Meanwhile, you can already test the new functionality by installing the next
version of our plugin.
tns plugin remove nativescript-telerik-ui-pro
tns plugin add nativescript-telerik-ui-pro@next
and then using this example
as a reference on how to use the new custom editors.
Please notice that the functionality is not yet officially released and is subject to some additional tests and might be changed if needed.
