You could try the textchanged event. Like this:

private void textBox1_TextChanged(object sender, EventArgs e)
{
  ((TextBox)sender).Text = ((TextBox)sender).Text.ToUpper();
  ((TextBox)sender).SelectionStart = ((TextBox)sender).Text.Length;
}

not as pretty as the keypress but it gets the job done. I would not use any of the other key events. Well maybe the keyup event.

What is wrong with the return key?

There is a forum for PDAs. There is also a separate category for compact framework here in the .net forum. You might want to try your luck there.
