Disable Web-scoped features on Web deletion

Question

I have a SPWeb ( http://example.com/site ), created used a custom web template, with several features activated on its scope.

When I delete the SPWeb it would be desirable that all the features activated at http://example.com/site would be deactivated (therefore running the FeatureDeactivating events on all features at that scope).

Some quick testing showed that sharepoint does not deactivate those features automatically.

How can I achieve this behavior programmatically?

Answer 1

Trap the WebDeleting method using a WebEventReceiver. Iterate over your activated features at that scope, then deactivate them.
