Hi, I always facing DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'ProductColor'. this issue, I checked all my data binding, its correct, how to fix this?

Below is my code for cs
using System;

using System.Collections.Generic;

using System.Data.SqlClient;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

//Step 1:

using System.Xml.Linq;

using Razorpay.Api;

using System.Configuration;

using System.Data;

namespace NewVersion.admin

{

public partial class productList : System.Web.UI.Page

{

    //step 2: retrieve CS from Global.asax

    string cs = Global.CS;

    protected void Page_Load(object sender, EventArgs e)

    {

        if (!IsPostBack)

        {

            BindProductTable();

        }

    }

    protected void btnAddProduct_Click(object sender, EventArgs e)

    {

        string productName = txtProductName.Text;

        string productImageURL = txtProductImageURL.Text;

        decimal price = decimal.Parse(txtPrice.Text);

        int quantity = int.Parse(txtQuantity.Text);

        string productStorage = txtProductStorage.Text;

        string productColor = txtProductColor.Text;

        string connectionString = ConfigurationManager.ConnectionStrings["productConnectionString"].ConnectionString;

        string query = @"INSERT INTO Product (ProductImageURL, ProductName, Price, Quantity, ProductColor, ProductStorage) 

                 VALUES (@ProductImageURL, @ProductName, @Price, @Quantity, @ProductColor, @ProductStorage)";

        using (SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["productConnectionString"].ConnectionString))

        {

            using (SqlCommand cmd = new SqlCommand(query, con))

            {

                // Supply input/data into parameters

                cmd.Parameters.AddWithValue("@ProductImageURL", productImageURL);
