Creating custom permission level in moss

Hi All,

Today we are going to create a custom Permission level for the site.

It is very simple process of understanding the SPRoleDefinition.

Assume that currentWeb is an instance of SPWeb and where in you want to create custom permission level, then write down this code.

currentWeb.AllowUnsafeUpdates = true;

SPRoleDefinition roleDefinition = new SPRoleDefinition();

roleDefinition.Name = "Custom Permission";

And then start giving all permisions that you want to give.

roleDefinition.BasePermissions =
SPBasePermissions.ManageLists
| SPBasePermissions.AddListItems
| SPBasePermissions.EditListItems
| SPBasePermissions.DeleteListItems
| SPBasePermissions.ViewListItems
| SPBasePermissions.ApproveItems
| SPBasePermissions.OpenItems
| SPBasePermissions.ViewVersions
| SPBasePermissions.DeleteVersions
| SPBasePermissions.CreateAlerts
| SPBasePermissions.ViewFormPages
| SPBasePermissions.ViewPages
| SPBasePermissions.ManagePermissions
| SPBasePermissions.EnumeratePermissions;

These permission are same as that we find in Site Settings->Permissions->Permission levels which is at _layouts/role.aspx location of the site.

You can get each and every permission enumeration here in SPBasePermissions. Every permission that you see on _layouts/role.aspx page is there in SPBasePermissions enumeration.


Once you do that all that remains is just add this SProleDenifition to the web.

currentWeb.RoleDefinitions.Add(roleDefinition);

currentWeb.AllowUnsafeUpdates = false;

That's it. you are done. When you open this permission set named "Custom Permission", you can see those options are by default selected for which you have given permission from code.
