I tweaked the ReduceText Method a bit, because i got an exception when the Text.Length is zero:

///
/// Reduces the text.
///
/// The text.
/// The reduced length text
protected virtual string ReduceText(string text)
{
if (text.Length > 0)
{
return text.Substring(0, text.Length – 1);
}
else
{
return String.Empty;
}
}
