Dynamically adding webpart properties

[robert110]

I have a webpart that displays departmental news. Every department have different news section for instance Admin dept have three news section: 1- Admin 2- HR 3- General Sales dept have four: 1- Company Sales News 2- Stock News 3- Global Market News 4- Sales Forecast Now, I want to expose these sections as properties of my WebPart so if a Sales user is logged in; when he will enter Edit Mode; he sees all four sections in Sales Dept and from which he can choose what all it is that he wants to see on the webpart. I can hardcode something like this:

  protected bool _CompanySales = true;
  [ Personalizable(PersonalizationScope.User), 
    WebBrowsable,
    WebDisplayName("Company's Sales News"), 
    WebDescription("Use this property to show/hide Company's Sales news")]
  public bool CompanySales  {
    get { return _CompanySales ; }
    set { _CompanySales = value; }
  }

  protected bool _StockNews= true;
  [ Personalizable(PersonalizationScope.User), 
    WebBrowsable,
    WebDisplayName("Stock News"), 
    WebDescription("Use this property to show/hide Stock News")]
  public bool StockNews{
    get { return _StockNews; }
    set { _StockNews= value; }
  }

  protected bool _GlobalMarketNews= true;
  [ Personalizable(PersonalizationScope.User), 
    WebBrowsable,
    WebDisplayName("Global Market News"), 
    WebDescription("Use this property to show/hide Global Market News")]
  public bool GlobalMarketNews{
    get { return _GlobalMarketNews; }
    set { _GlobalMarketNews= value; }
  }
// ...
// ETC

But I wouldn't have any knowldge of these sections because they are stored in the database. So I guess my question is; how can I dynamically define properties of a webpart by pulling the data from a datasource? Thanks in advance.
