C＃：用类对象列表填充DataGridView

Question

I have the following class which fills a list as shown bellow from an event when a button bound to each column is clicked on a DataGridView called MenuGrid:

public class orderedfood
{
     public string price;
     public string item;
}
List<orderedfood> order = new List<orderedfood>();
private void MenuGrid_CellClick(object sender, DataGridViewCellEventArgs e)
{
     order.Add(new orderedfood { item = MenuGrid.Rows[e.RowIndex].Cells[1].Value.ToString(), price = subtotal.ToString() });
}

This MenuGrid has the following format:

What I want to do is to reload the DataGridView bound to the order List, hence I tried the following code:

        MenuGrid.DataSource = null;
        MenuGrid.Rows.Clear();


        for (int i = 0; i < order.Count; i++)
        {
            MenuGrid.Rows.Add(order[i].item, order[i].price);


        }
        MenuGrid.Refresh();

This gives the following output, which is not what I want:

The final screenshot is correct on the number of rows but it doesn't include the name and the price of the the item.

Any suggestions?

Dont set DataSource to null. And also you can try this inside your for loop,

            DataGridViewRow row = new DataGridViewRow();
            dataGridView1.Rows.Add(row);
            dataGridView1.Rows.Insert(0, order[i].item, order[i].price);
