Why in THE WORLD, must I have properties in my object in order to see them in a DataGrid?

For instance, if I create collection Wookies, each wookie better have a:

  private m_hairColor;

  public string HairColor

  {

   get{return m_hairColor;}

   set{m_hairColor = value;}

  }

and not just

  public string HairColor;

or it will give you some error like “Wookies do not contain HairColor” when you try to display it in a DataGrid.

Look, I understand the niceties in creating properties, but sometimes, I don’t need to.

Also understand I am pissed off and didn’t feel like googling why.
