KeyPressed in textbox not working - c#-4.0

Question

I tried to get the code below working, but to no avail.
I have to make a login window, and except from the Log in button I want by pressing the Enter key in password textbox the result to be the same. C# 2010.
private void button1_Click(object sender, EventArgs e)
{
int ok=0;
if (textBox1.Text == "administrator" && textBox2.Text == "administrator")
{
ok = 1;
this.Hide();
Admin admin = new Admin();
admin.ShowDialog();
}
if (textBox1.Text == "jucator" && textBox2.Text == "jucator")
{
ok = 1;
this.Hide();
}
if (ok == 0)
{
label2.Text = "nume user sau parola incorecta";
label2.Visible = true;
}
}
private void textBox2_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Enter)
{
button1_Click(this, new EventArgs());
}
}

You should use the KeyUp event It's more reliable in you case.
Then check for the pressed key.
e.g.:
private void textBox2_KeyUp(object sender, KeyEventArgs e)
{
if (e.Key == Key.Enter)
{
//DoLogin... in your case it would be
button1_Click(null,null);
e.Handled = true;
}
else
{
e.Handled = false;
}
}
On a side note: I really discourage you to use that Log In method, comparing strings to a hardcoded strings is really a waste, there're better scenarios specially in an environment where you have multiple users Otherwise why would you require a login?
