Inheritance and Generics? Factory class?

Question

I have a grid class (will remove most of the properties to  keep it short)

 

 public class WinGrid

{

 

    public List<WinGridRow> Rows 

  {

     ... 

  } 

} 

 

 

public class WinGridRow

{

 

 

   public WinGridRow(WinGrid parent) 

    {

       // Many properties and methods

    }

} 

 

Basically I want to inherit the Grid class but the Rows property returns a list of GridRow. The GridRow class does what I what to do but I want to inherit it and add more specific methods and properties. I what to know the best approach and to go about it. Generics? Factory? 

 

Any help will be appreciated.

 

Thanks
