Question

Answer 1

Without changing that much your code, you could set the row.Visible property to false instead of just changing row.Selected. Anyway, the answer above is more performant and clean, you should try that.

Answer 2

if you want to display only the filtered rows use BindingSource.Filter property. Here is a good sample in MSDN

bindingSource.Filter = "columnname = 'value'";

private void button1_Click(object sender, EventArgs e)
{
    string searchValue = textBox1.Text;

     dataGridView1.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
     bindingSource.Filter = string.Format("{0} = '{1}'","YourColumnName", searchValue );
     //here you can do selection if you need
}

To remove filter use the following

bindingSource.RemoveFilter();

or

bindingSource.Filter = null;
