            bindingSource1 = new BindingSource(stockItems);

            // Assign the BindingSource as the DataSource for both DataGridViews
            dataGridView1.DataSource = bindingSource1;
            dataGridView2.DataSource = bindingSource1;

        public int Quantity { get; set; }
}

Hi @sanchita goel , Welcome to Microsoft Q&A,

Your problem lies in the conversion use of BindingSource and BindingList.

Refer to their official documentationBindingSource 和 BindingList.

using System.ComponentModel;
using System.Windows.Forms;

namespace xxx
{
    public partial class Form1 : Form
    {
        private BindingList<StockItem> stockItems;
        private BindingSource bindingSource1;
        public Form1()
        {
            InitializeComponent();
            InitializeData();
        }
        private void InitializeData()
        {
            // Create the BindingList to hold stock items
            stockItems = new BindingList<StockItem>();

            // Set the DataSource of the BindingSource to the BindingList
            bindingSource1 = new BindingSource { DataSource = stockItems };

            // Assign the BindingSource as the DataSource for both DataGridViews
            dataGridView1.DataSource = bindingSource1;
            dataGridView2.DataSource = bindingSource1;
        }

        private void textBox1_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyCode == Keys.Enter)
            {
                string enteredText = textBox1.Text;

                // Create a new stock item with the entered text and quantity 0
                StockItem newItem = new StockItem(enteredText, 0);

                // Add the new stock item to the BindingList
                stockItems.Add(newItem);

                // Clear the TextBox after adding the item
                textBox1.Clear();
            }
        }
    }
    public class StockItem
    {
        public string Name { get; set; }
        public int Quantity { get; set; }

        public StockItem(string name, int quantity)
        {
            Name = name;
            Quantity = quantity;
        }
    }
}
