Binding ObservableCollection to DataGridView

I am binding an observable collection (FoodList) to a BindingSource in my WinForm. This BindingSource is used by a datagrid on the form. I had assumed that when I added a new item to the collection it would raise an event and a new row would show up in my grid. This does not happen though. ``` namespace Foods { public class FoodList : ObservableCollection<Food> { } } private void frmFoods_Load(object sender, EventArgs e) { try { foodSource = new Source("Foods.xml"); foodBindingSource.DataSource = foodSource.Foods; } catch (Exception ex) { MessageBox.Show(ex.Message); } } private void AddFood() { using (frmFood frm = new frmFood()) { frm.ShowDialog(this); if (!frm.Canceled) { foodSource.Foods.Add(frm.Food); // <-- No new row. //foodBindingSource.ResetBindings(false); foodDataGridView.ClearSelection(); foodDataGridView.CurrentCell = foodDataGridView[0, foodDataGridView.Rows.Count - 1]; foodDataGridView.Focus(); } } } ```
