       private void editToolStripMenuItem_Click(object sender, EventArgs e)

        Form6 f = new Form6();
     f.label1.Text = dataGridView1.SelectedRows[0].Cells[0].Value.ToString();

    }

is the code correct?

Answer 1

If Form6 is not already opened then you will need to show it after assigning text to its label.

private void editToolStripMenuItem_Click(object sender, EventArgs e)
{
    Form6 f = new Form6();
    f.label1.Text = dataGridView1.SelectedRows[0].Cells[0].Value.ToString();
    f.Show();

}

If Form6 is already opened, you need to use the instance of Form6 and not to create new instance, you can use Application.OpenForms to get already opened forms.

Form6 f = (Form6)Application.OpenForms["form6"];
f.label1.Text = dataGridView1.SelectedRows[0].Cells[0].Value.ToString();
