I am pretty sure component edit has a role associated to it in TeamSite that can be changed. See TeamSite's user's guide about roles.
Thanks Alex for the reply.Yes, there are roles for component edit. But my use case is bit different.Suppose in a given page I have Component A and Component B. Now, when User A edit the page.. he can edit component A but not Component B and when User B edits the same page he is only allowed to edit Component B and not Component A.In both the scenario, User A and User B have the same role for component edit, but they are restricted to different set of components edit access.Just like we use for DCRsIs there any option to provide the Allowed list of users for a given component?
