Add this code to your Add button click event:

private void button1_Click(object sender, EventArgs e)
{
    for (int i = 0; i < checkedListBox1.Items.Count; i++)
    {
        if (checkedListBox1.GetItemChecked(i))
        {
            dataGridView1.Rows.Add(checkedListBox1.Items[i], "1");
        }
    }
}
