                try
                {
                    //Allow updating of some sharepoint lists, (here spUsers, spGroups etc...)
                    spWeb.AllowUnsafeUpdates = true;

SPRoleDefinition roleDefinition = spWeb.RoleDefinitions[permissionName];

foreach (string group in groupCollection)
{

SPGroup spGroup = spWeb.Groups[group];

SPRoleAssignment roleAssignment = new SPRoleAssignment(spGroup);
SPRoleDefinitionBindingCollection roleDefBindings = roleAssignment.RoleDefinitionBindings;

roleDefBindings.Add(roleDefinition);
spWeb.RoleAssignments.Add(roleAssignment);

roleDefinition.Update();
}

                }
                catch (Exception ex)
                {
                    //Error handling logic should go here
                    throw ex;
                }
                finally
                {
                    spWeb.AllowUnsafeUpdates = false;
                }
            });
        }

Ok this is it.

Well... I called above method from "FeatureActivated" event of a feature. For "FeatureDeactivating" event I tried to achieve the contrary to this, delete a permission level from a user group. But didn't succeed. :(

If you have any idea pls let us know.Thanks in advance.
