[Solved] NumericBox suppresses OnKeyDown for . and -

[Mark]

Hi,

RadNumericBox seems to suppress the call to OnKeyDown for the keys '.' and '-' but does call it for most other keys it considers valid (digits, left arrow, right arrow, delete, backspace). Can you confirm that this is true? If so, is this by design?

I can see suppressing the call for invalid keys like 'a' - 'z' but it seems inconsistent to call it for some valid keys and not others.I am trying to restrict user input to nonnegative integers so I do not want to allow . or - in the input and this behavior is preventing me from doing that customization cleanly.

Thanks!

Mark

Edited to add : I'm using C#/XAML so perhaps this issue isn't too important because I cannot really create a derived class as I would like to. This reminds me why I really don't like the complexity and limitations of COM.

Hi Mark,

Thank you for contacting us.

I must confirm that when such special character is typed, we mark this event as handled. This is intentional and the reason is that otherwise handling these characters causes the MS TextBox control to flicker.

If you have any other questions, do not hesitate to contact us again.
