If the textboxes are 'pre-loaded', which it seems they are, and, as you're not interested in sender/e, then you can call the button-click from the form_load:
private void Form1_Load(object sender, EventArgs e)
{
button1_Click(sender, e)
}
private void Form1_Load(object sender, EventArgs e)
{
button1_Click(sender, e)
}
