keyDown event is not working on textbox

I a have simple login form and I have set it's accept button property to "OK" button, and I have a textbox "username" which I set it's KeyDown event to do some processing. the Ok has enabled set to false. 

btnOk.Enbled = false;  
this.AcceptButton = btnOk;
txtUsername.KeyDown += new KeyEventHandler(KeyDownHandle);

when I hit enter in the username textbox I do some processing and then set accept button enabled to true. 

private void KeyDownHandle(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Enter)
    {
        // some processing
        btnOk.Enabled = true;
        txtPassword.Focus();
    }
}

then I write password in password textbox and hit enter so "OK.Click" is triggered.

but the problem is the keyDown is not working because "accept button".
what can I do to solve this?

Edit: Just want to say the problem is resolved if I set acceptButton to "none" but that's not what I'm looking for.

Why don't you remove this.AcceptButton = btnOk from the constrctor (I suppose) and put it in the KeyDownHandler, that way btnOk will accept Enter key only after it is enabled and after the username has been inserted. so the code should be like this:

btnOk.Enabled = false;
txtUsername.KeyDown += new KeyEventHandler(textBox1_KeyDown);
btnOk.Click += new EventHandler(button1_Click);


private void KeyDownHandle(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Enter)
    {
        // some processing
        btnOk.Enabled = true;
        this.AcceptButton = btnOk;
        txtPassword.Focus();
    }
}
