Populate Combobox

[functionalCode]

Hello Everyone,

I have a database that has some items and I would like to fill a combo box with the items and have the combobox selected value set the corresponding item ID. I have seen so many ways to do this I am not sure which way to go. Any help is appreciated. This is what I have so far:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace DBApp
{
    public partial class Form1 : Form
    {
        DB db;
        public Form1()
        {
            DataSet ds;
            db = new DB();
            ds = db.getRecords();
            InitializeComponent();
            
    
            comboBox1.DataSource = ds;
            comboBox1.DisplayMember = "PlatformName";
            comboBox1.ValueMember = "PlatformID";
        }
    }
}

With the code above an exception gets thrown:

The error is:
Cannot bind to the new display member.
Parameter name: newDisplayMember

Thanks.
