Passing data to DataGridViews

I have text boxes on my second form and a send button which is in the code shown below. 

private void button1_Click(object sender, EventArgs e)
{
    Form1 f1 = new Form1();
    f1.PassName = richTextBox1.Text;
    f1.PassLastName = richTextBox2.Text;
    f1.PassAge = comboBox1.Text;
    f1.PassGender = richTextBox3.Text;
    f1.ShowDialog();
}

and a DataGridView on form 1 with this code

public partial class Form1 : Form
{
    private string name;
    private string lastName;
    private string age;
    private string gender;

    public string PassName
    {
        get { return name; }
        set { name = value; }
    }

    public string PassLastName
    {
        get { return lastName; }
        set { lastName = value; }
    }

    public string PassAge
    {
        get { return age; }
        set { age = value; }
    }

    public string PassGender
    {
        get { return gender; }
        set { gender = value; }
    }

    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        int n = dataGridView1.Rows.Add();
        dataGridView1.Rows[n].Cells[0].Value = name;
        dataGridView1.Rows[n].Cells[1].Value = lastName;
        dataGridView1.Rows[n].Cells[2].Value = age;
        dataGridView1.Rows[n].Cells[3].Value = gender;
    }

    private void mnuExit_Click(object sender, EventArgs e) //adding the quit on the top file with caution message
    {
        if (MessageBox.Show("Do you really want to Quit?", "Exit", MessageBoxButtons.OKCancel) == DialogResult.OK)
        {
            Application.Exit();
        }
    }

    private void addTask_Click(object sender, EventArgs e)
    {
        Form2 f2 = new Form2(); //show form2 so user can input data
        f2.ShowDialog();
    }

    private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
    {

    }

}`

This is fine if I want to send one set of data to the DataGridView, but if I add new information again then this opens a new DataGridView and stores it to another seperate DataGridView then I have two DataGridView forms. I want to put all the data onto one DataGridView and keep adding rows. So when the user clicks the add button on the first form with the DataGridView, it opens up the TextBox form which is form 2, then the user fills out the information and clicks the send button which sends the information back to the DataGridView, however this then opens up a new window with a new DataGridView. I dont want this to happen I want it to keep adding rows on the first form.
Could someone show me how to do this?

You can use ShowDialog(this) and Owner to get the parent form's property.

Form1

private void Form1_Load(object sender, EventArgs e)
{
    //Move to Form1_Activated
    this.Activated += new System.EventHandler(this.Form1_Activated); //connect
}

private void Form1_Activated(object sender, EventArgs e)
{
    int n = dataGridView1.Rows.Add();
    dataGridView1.Rows[n].Cells[0].Value = name;
    dataGridView1.Rows[n].Cells[1].Value = lastName;
    dataGridView1.Rows[n].Cells[2].Value = age;
    dataGridView1.Rows[n].Cells[3].Value = gender;
}

private void addTask_Click(object sender, EventArgs e)
{
    Form2 f2 = new Form2(); //show form2 so user can input data
    f2.ShowDialog(this);//set this form as Owner
}

Form2

private void button1_Click(object sender, EventArgs e)
{
    Form1 f1 = (Form1)this.Owner;//Get the Owner form
    f1.PassName = richTextBox1.Text;
    f1.PassLastName = richTextBox2.Text;
    f1.PassAge = comboBox1.Text;
    f1.PassGender = richTextBox3.Text;
    //f1.ShowDialog();
    f1.Show();
    this.Close();
}
