Hi Steve .,
1. You can access the RadEditor after you map the external template when you work with additional provider. You can do this inside PreRender and then you can set the Content of the RadEditor. In this case it is better to use with local resources instead of embedded resources, because you should use external template
2. If you have a custom module you can use Messages
.MyKey. In this case you can inject the code in the backend of a custom view. All templates should be embedded.
