I am trying to programmatically add properties (and their values) to a user profile, but it does not appear that the it is saved to the database... Here is the code I am using, hopefully someone can point out what I am missing or a best practice on this subject... TIA

 piUser.Profile.SetProfileProperty("ExtraInfo", ExtraInfo)

SetApplicationName(piUser.PortalID)

 ProfileController.UpdateUserProfile(piUser, piUser.Profile.ProfileProperties)

End If

First - dnn no longer uses the aspnet_Profile table.

Second - the dnn Profile table is used for Personalization which is a different kind of "profile" - it saves things like whether you are using the Text Editor in Rich Text or PLain Text.

The dnn Table that stored the Profile is UserProfile.

This stores the UserID/ProfileDefinitionID and Profile Value.

So to programmatically use the profile - you need to create a Profile Definition (you can do this programmatically using ProfileController.AddPropertyDefinition().   You can then use the SetProfile method you mentioned above using a "name" that matches the property Definition you created.

Using SetProfile where the PropertyDefinition has not been created does nothing.
