If you are looking to do it via the server side you could do a simple regex that would replace any double spaces with a singular space

RegexOptions options = RegexOptions.None;
Regex regex = new Regex(@"[ ]{2,}", options);     
MyTextBox.Text= regex.Replace(MyTextBox.Text, @" ");

If you wan to do it on the client side you can still use the same regex but do it on JavaScript and fire it on the onBlur event
