Button disappears but the other column members of the row remains visible in datagridview c#

Question

I am writing a code to make sure that if the translate button is pressed a new row appears but all the row members except string text are visible..Now i have written the code but it only makes the button disappear and all the members are still visible.

This is the view after the button is pressed..

Now the button is invisible but all the other members are still visible.this is the code i have tried..

    private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
    bool ce = false;
    bool check = true;
    Column_handling();
    DataGridViewTextBoxCell c = new DataGridViewTextBoxCell();
    if(!(dataGridView1.Rows[e.RowIndex].Selected))
    {
        dataGridView1.Rows[e.RowIndex].Selected = false;
        if (e.ColumnIndex == 10)
        {
            if((Convert.ToInt16(this.dataGridView1.Rows[e.RowIndex].Cells[0].Value) == Convert.ToInt16(this.dataGridView1.Rows[e.RowIndex + 1].Cells[0].Value)) && (Convert.ToInt16(this.dataGridView1.Rows[e.RowIndex].Cells[1].Value) == Convert.ToInt16(this.dataGridView1.Rows[e.RowIndex + 1].Cells[1].Value)))
            {
                ce = true;
            }
            if(!ce)
