Delete list item with BindingNavigator, not correct item

Question

I use a BindingNavigator to delete items from the products list, via the datagridview. (The methodcall main.DeleteProduct() calls a repository to delete from database).

I need some help to improve the code of the ..DeleteItem_Click event. When I click on a cell/or row, and then delete button (BindingNavigator), it never deletes that row. It deletes the row below, or if it's the last row, the row above, and if only one row, a null is cast. Shouldn't the bindingSource.Current be same item as currentrow of datagridview?

Also, is the way I'm casting the current item using the bindingsource a good way? Would appretiate better code suggestion if you have.

Cheers!

 public partial class Form1 : Form
{      
    private MainBL main = new MainBL(); 
    private   List<Product> products = new List<Product>

    private void Form1_Load(object sender, EventArgs e)
    {

        bsProducts.DataSource = products;         // BindingSource
        bnProducts.BindingSource = bsProducts;    // BindingNavigator
        dataGridView1.DataSource = bsProducts;    //
    }

    private void bindingNavigatorDeleteItem_Click(object sender, EventArgs e)
    {

        Product product = (Product)bsProducts.Current;

       // Putting a breakpoint here, shows the identity property is not the same
       // as row selected in datagridview. 

        main.DeleteProduct(product);

    }

I understood now that the row is deleted before the CellClick event fires. So I make it work as intended by instead putting the code in the _MouseDown event of the delete button. Not sure if this is the most proper solution though..

    private void btnDeleteProducts_MouseDown(object sender, MouseEventArgs e)
    {
        Product product = (Product)bsProducts.Current;
        if (product != null)
        {
           main.DeleteProduct(product);
        }                 
    }
