Creating SharePoint 2010 permission levels

Ever needed to control a set of users and level of access they have to SharePoint document libraries, lists, sites etc?

In SharePoint 2010 there are few new methods that simplify the life from a developers stand point to leverage custom permissions levels.

Here I`ll show you how to create custom permission levels programmatically, so you can call them from the feature receiver when creating a site from your site template:

1. First we create custom permission level with the name and description and set of permissions you can find here.

SPRoleDefinition role = new SPRoleDefinition();
                role.BasePermissions = SPBasePermissions.OpenItems | SPBasePermissions.EditListItems | SPBasePermissions.ViewListItems | SPBasePermissions.ViewPages | SPBasePermissions.Open | SPBasePermissions.ViewFormPages;
                role.Name = “My Role Name”;
                role.Description = “My Role Description”;
                rootWeb.RoleDefinitions.Add(role);

2. Then we assign a set of permissions to an existing group in this case called MyGroup

 SPRoleAssignment roleAssignment = new SPRoleAssignment(rootWeb.SiteGroups["MyGroup"]);
                roleAssignment.RoleDefinitionBindings.Add(role);
                rootWeb.RoleAssignments.Add(roleAssignment);

If you’re reading this you probably spent about 10 minutes trying to find this particular code. Here is something I found very usefull if you’re developing for MOSS or SharePoint 2010: a great set of SharePoint snippents from CodePlex.

Enjoy!
