Sample Event Handler to set Permissions

Please note that it is a sample code and should not be used in production environment without some major changes. For example - getting the user name and password of a user with elevated permissions on the list should be from an encrypted config file. Another example for a change is changing the logging to use a trace log.
All that aside, this is still a good working example that shows some interesting things:

• How to get a list item in the event handler


• How to impersonate another user totaly (not using RunWithElevatedPrivilages)


• How to change an item's permissions


• How to create a new permission role in a web site


• How to check if a role exists or not (nice trick there - can you spot it?)
