BindPropertyUsage.cs

// Take your datagrid, add a CellFormatting function.

  private void dgYourDataGrid_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
  {
      if ((dgYourDataGrid.Rows[e.RowIndex].DataBoundItem != null) &&
          (dgYourDataGrid.Columns[e.ColumnIndex].DataPropertyName.Contains(".")))
      {
          e.Value = Misc.BindProperty(
                        dgYourDataGrid.Rows[e.RowIndex].DataBoundItem,
                        dgYourDataGrid.Columns[e.ColumnIndex].DataPropertyName
                      );
      }
  }
