I'm trying to insert and change a text of a button but it show as

Here is my code

Button SaveButton  = new Button();
Button DeleteButton  = new Button()
SaveButton.Text = "Save";
DeleteButton.Text = "Delete";
object[] Data = 
{
  ProductList[i].ProductName,
  ProductList[i].ProductPrice.ToString(),
  ProductList[i].ProductCreationCost.ToString(),
  ProductList[i].ProductStock.ToString(),
  ProductList[i].ProductBarcode.ToString(),
  ProductList[i].ProductImageLoc.ToString(),
  SaveButton,
  DeleteButton,
};
ItemDataGrid.Rows.Add(Data);

I just want the button names to be "Save" and "Delete".

You are inserting SaveButton and DeleteButton objects into the array. Just insert the text property of buttons like below.

object[] Data = 
    {
        ProductList[i].ProductName,
        ProductList[i].ProductPrice.ToString(),
        ProductList[i].ProductCreationCost.ToString(),
        ProductList[i].ProductStock.ToString(),
        ProductList[i].ProductBarcode.ToString(),
        ProductList[i].ProductImageLoc.ToString(),
        SaveButton.Text,
        DeleteButton.Text,
    };

Your question is about setting the button text of a DataGridView cell button. Here's an alternative to the currently accepted answer that uses the UseColumnTextForButtonValue and Text properties of the Column to set "Save" and "Delete" for the buttons. This example also uses the DataSource property of the DataGridView to attach a list of records where the Record class represents a row of data. This often makes things easier because you can work with the underlying data directly. The initialization code is shown below.

The data source is a BindingList<Product> containing objects of a class you have defined to represent a row:

// Minimal product class for example
class Product
{
    // Read-only cells for this example.
    public string Name { get; internal set; }
    public double Price { get; internal set; }
    public string Barcode { get; internal set; } =
        $"*{Guid.NewGuid().ToString().Substring(0, 8).ToUpper()}*";
}

Then in the main form, the Load event can be used to set up the columns and formatting, including the button text.

protected override void onl oad(EventArgs e)
{
    base.OnLoad(e);
    initBarcodeFont();
    dataGridView.AllowUserToAddRows = false;
    dataGridView.DataSource = Products;
    dataGridView.RowTemplate.Height = 100;

    #region F O R M A T    C O L U M N S
    DataGridViewColumn col;
    Products.Add(new Product());

    // Format existing Name column
    dataGridView.Columns[nameof(Product.Name)].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;

    // Format existing Barcode column
    col = dataGridView.Columns[nameof(Product.Barcode)];
    col.AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;
    col.DefaultCellStyle.Font = _barcodeFont;

    // Format existing Price column
    col = dataGridView.Columns[nameof(Product.Price)];
    col.AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;
    col.DefaultCellStyle.Format = "N2";

    // Add the Save button column and format the button style.
    col = new DataGridViewButtonColumn{
        Text = "Save",
        UseColumnTextForButtonValue = true,
        Width = 90,
        FlatStyle = FlatStyle.Flat
    };
    col.DefaultCellStyle.BackColor = Color.AliceBlue;
    dataGridView.Columns.Add(col);

    // Add the Delete button column and format the button style.
    col = new DataGridViewButtonColumn
    {
        Text = "Delete",
        UseColumnTextForButtonValue = true,
        Width = 90,
        FlatStyle = FlatStyle.Flat
    };
    col.DefaultCellStyle.BackColor = Color.AliceBlue;
    dataGridView.Columns.Add(col);
    Products.Clear();
    #endregion F O R M A T    C O L U M N S

    // Add a few products
    Products.Add(new Product { Name = "Coffee", Price = 13.99 });
    Products.Add(new Product { Name = "Milk", Price = 5.49 });
    Products.Add(new Product { Name = "Eggs", Price = 4.29 });
}
BindingList<Product> Products = new BindingList<Product>();
