You can try adding code to a CellEndEdit event handler, then you can show an already created hidden DataGridView as the second one or you can also create that DataGridView on the fly. It's up to you. I prefer to show that DataGridView and initialize the number of rows. Here is the code helping you understand the idea:

//First you have to layout 2 DataGridViews at design time and set the Visible of the second 
//DataGridView to false
//Your dataGridView2 should also have 2 columns added at design time as shown
//in your second picture.
private void dataGridView1_CellEndEdit(object sender, DataGridViewCellEventArgs e){
  //Suppose the column with header Total kaka has name TotalKaka
  if (dataGridView1.Columns[e.ColumnIndex].Name == "TotalKaka") {
      int i;
      if (int.TryParse(dataGridView1[e.ColumnIndex, e.RowIndex].Value.ToString(), out i))
      {
          dataGridView2.Rows.Clear();
          dataGridView2.Rows.Add(i);
          for (int j = 0; j < i; j++)
             dataGridView2[0, j].Value = j + 1;
          dataGridView2.Show();
          dataGridView2.CurrentCell = dataGridView2[1, 0];
          dataGridView2.Focus();          
      }
  }
}
//you should have some Submit button to submit the values entered into the second
//dataGridView, we should process something and surely hide the dataGridView2
private void submit_Click(object sender, EventArgs e){
    dataGridView2.Hide();
    //other code to process your data
    //....
}

NOTE : This answers to your actual requirement in this question, I guess you may have more problems such as How to process the data entered in dataGridView2 ? How to show the dataGridView2 in another form? ... such problems do exist and I think you should ask for the solution in other questions, don't try asking for solving them right in this question.
