Allow the user to enter negative numbers in the NumericTextBox
In the NumericTextBox typing the character "-" is not allowed meaning that the user can not directly type a negative number.  The only way for a negative number to be specified is by clicking the down arrow to progress below 0 to get the dash to show up.

verified this behavior in FF 16 on Win8. Will fix.

This is not working in Mozilla Firefox.  Open the jsbin link provided by the Admin in Mozilla and you will easily see this is not working.

I have exactly the same problem, the numeric keypad "-" works but not on the regular keyboard.

If you type a hyphen into the demo box here (http://api.jquery.com/keyup/), what keycode do you get?  I get 173 for the hyphen and 109 for the minus sign.  NumericTextBox gives the same behavior on my officemate's computer, too, even though it's a totally different model (still Windows 7, though).

I just noticed, this only happens on Firefox (16.0.2).  I tried your example in Chrome and IE, and it works as you'd expect.

I've tested this on three separate machines, OSX an Windows, with the numeric keypad and the combined minus/hyphen key and cannot duplicate this behavior. It worked for me in every case.

When you get a keypress event, minus and hyphen have the same code (ascii 45 or 0x2d).  When you look at keydown or keyup, though, minus is code 109 and hyphen is 173.

I think the relevant code is in _prevent: function(key), in kendo.numerictextbox.js (and mirrored in kendo.all.js, kendo.web.js, and the min.js versions).

(key == 189 || key == 109)
could be
(key == 189 || key == 109 || key == 173)

Brandon Satrom: I can't type a hyphen into your example (http://jsbin.com/elohuw/1/).  As Anonymous said, the minus sign on the numeric keypad works, but the hyphen that shares a key with the underscore fails.  Of course, many laptops don't have a numeric keypad.

Minus sign works only with numeric keypad. '-' on regular keybord doesn't work.

Hi Brandon,

I'm unable to replicate this behavior using a bare-bones NumericTextBox in JSFiddle. Can you check the following and compare against your implementation. Perhaps you have a config mismatch?
