Could someone show me how to create 2 new properties for the DataGridView?

1. Add a .Info property to each Rolumn of the DataGridView.

2. Add a .LastName property to each Row of the DataGridView.


So when the Grid's CellChanged even fires, I can do something like this...
TextBox1.Text = DataGridView1.Columns(theCurrentColumn).Info

Is that possible?
