Datagridview remove row and save to txt file

C#

Hello

I have two datagridviews-- Datagridview1 and datagridview3 (datagridview2 i use for something else)
And one button remove row on the Form.
if i have multiple rows in datagridview3 and hit the button the rows are removing one by one.
if the datagridview3 is empty you will be asked to save a file.
That works well.
So far so good.
But if i use the datagridview1 and i have also rows in it.
And i use the button remove row the rows are also removing one by one.
until the datagridview1 is completely empty.
Now i get also the question to save the file.
And that's is what i don't want with datagridview1.
I want this option only working on datagridview3.
regards

What I have tried:

private void Bt_Remove_Row_Click(object sender, EventArgs e)
        {
            foreach (DataGridViewRow row in dataGridView3.SelectedRows)
            {
                dataGridView3.Rows.RemoveAt(row.Index);
            }
            foreach (DataGridViewRow row in dataGridView1.SelectedRows)
            {
                dataGridView1.Rows.RemoveAt(row.Index);
            }

            if (dataGridView1.Rows.Count == 0)

            {
                Bt_Remove_Row.Enabled = false;
                Bt_Print.Enabled = false;
                Bt_Clear_List.Enabled = false;

                if (dataGridView3.Rows.Count == 0)

                {
                    Bt_Remove_Row.Enabled = false;
                    Bt_Print.Enabled = false;
                    Bt_Clear_List.Enabled = false;
                    Bt_Borrowd.Enabled = false;
                    Bt_Save_Borrowd.Enabled = false;

                    DialogResult dialogresult = MessageBox.Show("WEET U HET ZEKER", "DE LIJST UITGELEEND GEREEDSCHAP WORD LEEG GEMAAKT", MessageBoxButtons.YesNo, MessageBoxIcon.Warning);

                    if (dialogresult == DialogResult.Yes)
                    {
                        File.WriteAllText(UitleenBestand, String.Empty);
                        MessageBox.Show("BESTAND UITGELEEND GEREEDSCHAP IS AAN GEMAAKT", "BESTAND!!!", MessageBoxButtons.OK, MessageBoxIcon.Information);
                        Lb_Uitleen.Text = ("");
                    }
                    if (dialogresult == DialogResult.No)
                        Bt_Borrowd.Enabled = true;
                }
                else
                {
                    Bt_Remove_Row.Enabled = true;
                    Bt_Clear_List.Enabled = true;
                    Bt_Print.Enabled = true;
                }
            }
        }
