    public int quantity;
 }

 List<Order> orders = new List<Order>();
 myDataGrid.DataSource = orders;

Answer 1

您可以对要隐藏的每个列执行以下操作：

myDataGrid.Columns[0].Visible = false;

Answer 2

After you have set the DataSource and populated the columns, you could iterate through the generated columns and hide/remove some of them:

foreach (var column in gridView1.Columns.OfType<DevExpress.XtraGrid.Columns.GridColumn>())
{
    if (column.FieldName == "MemberToBeHidden")
    {
        // Just hide it by default, user can still choose to show it later
        column.Visible = false;

        // Or completely remove from the grid
        gridView1.Columns.Remove(column);
    }
}

Or if you don't want the field to appear at all, you could mark it with BrowsableAttribute :

class Order
{
    public int IdOrder;
    public string Product;
    public double Price;
    public int quantity;
    [Browsable(false)]
    public string MemberToBeHidden;
}

Answer 3

您应该禁用datagridview的AutoGeneratedColumns属性，使用与不想显示的属性相同的列名手动创建列，然后将数据源绑定到该列。
