I want to obtain other information about rows and cells (such as their locations), how do I do that?

There has to be some problem with your printing code. Try debug that or post it here.

Try using GetCellDisplayRectangle method.

try
{
  Rectangle cellRectangle = dataGridView1.GetCellDisplayRectangle(0, 0, true);
  Console.WriteLine("The cell is located at " + cellRectangle.X + ", " + cellRectangle.Y + ".");
}
catch (ArgumentOutOfRangeException e)
{
  Console.WriteLine("ArgumentOutOfRangeException. Additional info: " + e.Message);
}

The code is posted here and the printing code is the second row from the end

DataGridView dataGridView2 = new DataGridView();
      DataTable dataTable = new DataTable();
      dataTable.Columns.Add("My Column");
      dataTable.Rows.Add("My Cell Value");
      dataGridView2.DataSource = dataTable;

public Form1()
{
  InitializeComponent();
  this.Load += new EventHandler(Form1_Load);
}


private void Form1_Load(object sender, System.EventArgs e)
{
  DataGridView dataGridView1 = new DataGridView();
  DataTable dataTable = new DataTable();
  dataTable.Columns.Add("My Column");
  dataTable.Rows.Add("My Cell Value");
  dataGridView1.DataSource = dataTable;
  this.Controls.Add(dataGridView1);
  Console.WriteLine("There are " + dataGridView1.Rows.Count + " rows in your table.");
}

1. Get rid of binding source and use this:

DataGridView dataGridView2 = new DataGridView();
DataTable dataTable = new DataTable();
dataTable.Columns.Add("My Column");
dataTable.Rows.Add("My Cell Value");
dataGridView2.DataSource = dataTable;

DataView dv = dataTable.DefaultView;
dv.RowFilter = ...

static constructor can be useful

public class Test
{
   // Constructor
   public Test(){}

   public static Color GetColor()
   {
      return Color.White;
   }
}

// somewher in your app

Color c = Test.GetColor(); // Test t = New Test() was never called.

No such thing. static is usefull if you call function without intilizing class. If you intilize, constructor is called
