This is just a sample, how you call the public method in main form from child form:

public class Products : Form
{
    public void UpdateProductList()
    {
        // do something here
    }

    private void buttonOpenChildFormClick(object sender, EventArgs e)
    {
        using (var addProduct = new Add_product(this)) //send this reference of MainForm to ChildForm
        {
            addProduct.ShowDialog();
        }
    }
}

public class Add_product : Form
{
    private readonly Products _products;

    public Add_product(Products products) //send reference of MainForm to ChildForm
    {
        _products = products;
    }

    private void button1_Click(object sender, EventArgs e)
    {
        _products.UpdateProductList();
    }
}
