Hi Adrian

If you are using a viewmodel there are not tags or loops from the 'old' template world. It is either one or the other. The viewmodels are instead of template tags.

When in a master template, you are using the pageviewmodel which can be found here: https://doc.dynamicweb.com/api/html/8175ac67-de8b-696a-7436-6505c1a61e47.htm

The list of external providers is not exposed on the viewmodel, but can be accessed directly in the API:

using Dynamicweb.Security.UserManagement.ExternalAuthentication;
ProviderCollection providers = Provider.GetActiveProviders();

Be aware that GetActiveProviders will result in a database call and has no caching whatsoever. Same as with the DWExtranetExternalLoginProviders loop.

Hi Nicolai,

Thank you. Any chance this loop will benefit from caching in the nearest future? For B2C this is a pretty common request and making database calls everytime we load the list of providers in the login preview, would affect the performance.

Thank you,

Adrian

Maybe it should have. But, the loop and the feature was originally made to be on a dedicated login page and not on all pages. If you want the login feature on all pages, it is easy to cache it your self. I am not a fan though...

It might be helpful to look at how some of the champions of ecommerce does it - most of them have dedicated login pages i.e. https://www.asos.com (also with external auth), amazon and a few others.
