Permissions(user has not created list item but should only be able to edit their own)

Question

Hope you can help.

Ok so I have a list with a field called Owner which is derived from the active directory, this is the person who should be able to edit the list item in which they are assigned to. They will not create the list item which includes their name but must be able to edit their own and no other users(owners) assigned list item/s.

Hope this makes sense.

Thanks

This isn't supported by SharePoint, so you need to set specific permission on each item, which will only perform well if you have a limited number of items in the list.

The setting of permission, can be done:

• Manually like this:
  • Open list with item
  • Select the item
  • In the ribbon click Item Permissions
  • In the ribbon click Stop Inheriting Permissions (and OK)
  • Select all users/groups with too many rights
  • In the ribbon click Remove User Permissions (and OK)
  • In the ribbon click Grant Permissions
  • Select the owner grant Contribute permissions OK
  • Repeat for other missing permissions
• With SharePoint designer workflow using custom activities like http://spdactivities.codeplex.com/
• Using code in an event receiver
