put checked row from one datagridview to another .

Question

Hello Programmers ,
 I have 2 datagridview
dgv1
dgv2
dgv1 has some columns including 1 CheckBoxColumn  ,dgv2 has Some columns but no CheckBoxColumn .
I want functionality which enables me , when i check CheckBoxColumn ,data of that particular Row should be selected and go into Dgv2 .
this is how i put selected rows from dgv1 to dgv2  .
But if i cancel check (or unckeck) ,checked checkBox in dgv1  that particular row should be deleted from dgv2 .
Help me to fix this . i'll be thankful of u guys ,looking forward to this. :)

here is my code
 consider datagridview6= dgv1 and datagridview10 = dgv2

private void dataGridView6_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
    dataGridView10.Visible = true;           
         if (dataGridView6.CurrentCell.ColumnIndex == 7)
            {
                if (dataGridView6.CurrentCell.Value != null)
                {
                    bool checkstate = (bool)dataGridView6.CurrentCell.Value;

                    if (checkstate == false)
                    {
                        dataGridView6.CurrentCell.Value = true;                                           
                    }
                else
                 {//here help in logic to delete unchecked row
                    dataGridView6.CurrentCell.Value = false;
                     int j= int.Parse(dataGridView6.Rows[e.RowIndex].ToString());
                     dataGridView10.Rows.Remove(dataGridView10.Rows[j]);
                  }
               }
         else
         {dataGridView6.CurrentCell.Value = true;
           dataGridView10.Rows.Insert(i);          dataGridView10.Rows[i].Cells[1].Value=dataGridView6.CurrentRow.Cells[2].Value.ToString();
dataGridView10.Rows[i].Cells[2].Value = dataGridView6.CurrentRow.Cells[3].Value.ToString();
dataGridView10.Rows[i].Cells[3].Value = dataGridView6.CurrentRow.Cells[5].Value.ToString();
           }
     }

/* in this logic checked row is being selected in dgv2 but on unchecking it delete is not working.
