  1. Derive a class that inherits from the DomainUpDown control from or the NumericUpDown control.
  2. Declare a new Private method. Name the method UpdateEditTextBase. To do this, use the following code.
    private void UpdateEditTextBase()
    {
    		base.UpdateEditText();
    }
  3. Override the UpdateEditText method in your inherited class. To do this, use the following code.

    {
    		Invoke(new MethodInvoker(UpdateEditTextBase));
    }
