Am working in ektron 9.0. I read about the custom permission from below article Information about Custom Roles for your Developer
In that i found two methods GetRolePermissionSystem and GetRolePermissionFolder mentioned.Is anyone know which ektron api these methods available.
Also i would like to know that, is there any way to associate a custom permission with a content or a folder?
This is an older API and not a Framework API call. This is an example of using the API:
Ektron.Cms.CommonApi comApi = new Ektron.Cms.CommonApi();
if (comApi.GetRolePermissionSystem("MyCustomRoleAdmin", comApi.UserId))
That example is for a system wide custom role that is not specific to a folder. While the article you referenced seems to imply that GetRolePermissionFolder would work for a folder, I have never tried it.
