My user model has a list called permissions which holds the permissions of the current user. (eg: CAN_EDIT_ACCOUNT)

Lets say the main form has buttons for every module and we need to enable a button if the user has permissions to access that particular module (eg. btnBankAccountModule should be enabled to access BANK ACCOUNT module if the user has permission). There is a public bool property for every button in the form and in the Load event, OnControlPermission will be fired and LoginPresenter will listen to this event and it will set the properties True or False based on the details provided by the UserPermissionService. (please see ControlPermission() method in the LoginPresenter code)

        var BankAccountPresenter = new BankAccountPresenter(modle, view, dataService, PermissionsService);
        BankAccountPresenter.Show();

3. Or else is it better to instantiate an new instance of UserPermissionService in the Main form ? Then how should I inject the current user to the permission service?

NOTE : I AM NOT FAMILIAR WITH IOC so I'd appreciate if you could give an other explanation which would go inline with my current work?
