title: Masked Textbox for Double?
body: <p>I have a Masked Textbox and I want it to be able to accept a double value. There shouldn't be a limit of sorts to the amount of characters which can fit before/after the decimal point.</p>
  
  <p>I realise there are other ways of doing this such as overriding key input events or using a numeric up down but I'm just asking whether its possible using a mask.</p>
  
  <p>I've tried 9999999999.99999999 - but its giving me a lot of problems - such as:</p>
  
  <p>1 2   3    4  . 6
  being accepted as input (spaces included) and me not being able to drop the . wherever I want it.</p>
