winform C# DataGridView How to Update Columns bound to Generic List

Question

Currently I have a DataGridView that is bound to a Generic List. So I have:

dataGridView1.DataSource = ProductBO.GetProducts(); 

This displays about 300 products and need the ability to update the price and quantity columns when needed. Whats the easiest/cleanest way? There must be some event like to use txtPrice_AfterUpdate() that can be used. Coming from a Webform backgraound and MS Access Im not sure the route to take here. Thanks in advance.

Unless it's a really expensive operation you could just refresh the DataSource, literally call that code again.

public void RefreshProducts()
{
    dataGridView1.DataSource = ProductBO.GetProducts();
}
