Answer 1

You can do like this

 private void datagridview1_SelectionChanged(object sender, EventArgs e)
 {
   if (datagridview1.SelectedCells.Count > 0)
   {
     foreach (DataGridViewCell cell in dataGridView1.SelectedCells)
     {
       int selectedrowindex = cell.RowIndex;
       DataGridViewRow selectedRow = datagridview1.Rows[selectedrowindex];  
       string a = Convert.ToString(selectedRow.Cells[0].Value); 
      }
    }
  }
