Answer 1

I found that "Find" method cannot be used directly with BindingList, but fortunately there is an alternative, using IEnumerable. After Implementing a BindingList in the project, I can filter a bound datagridview using the next code:

    private void button1_Click(object sender, EventArgs e)
    {
        var qry = (from p in dc.Products
                   select p).ToList();
        BindingList list = new BindingList(qry);
        IEnumerable selection = list.Where(m => m.ProductName.Contains(textBox1.Text) == true);
        productBindingSource.DataSource = selection;
    }
