Solution 2

Handle TextBox.ModifiedChanged[^] events.

When user has enter enough text, you can set focus to the next TextBox.

C#

private void TextBox1_TextChanged(object sender, EventArgs e)
{
  this.textBox1.Modified = false; // Get next event.

  // Check text input
  if (this.textBox1.Text.ToUpper() == "AGREE")
  {
    Control nextInTabOrder = GetNextControl(this, true);
    nextInTabOrder.Focus();
  }
}

Is good (sorry, meant to hit 5), but I would recommned OP create a custom control that can handle multiple triggers for when the content of a given textbox is 'complete'. By number of characters, by content match, by format, etc... The custom control should raise a custom event to notify the parent, and this is the event that should be handled there to advance focus. That way, the control takes care of monitoring it's own content and deciding when it is 'done', then just tells the parent when that happens.

Thanks fcronin
You are right about a custom control of TextBox class. It will be a more elegant solution.
How about add your own solution with a custom control ? :-)
