Decimal textbox validation behavior

[michaelcress]

If anyone is interested, I can contribute a Behavior that will validate user input for decimal values. It supports the use of both '.' and ',' to represent decimal points and also allows for excluding negative numbers, all configurable via XAML. I'll probably add an option to specification of upper and lower bounds for the values as well, prior to committing.

Would this be similar to the recently added textbox mask? @IbraheemOsama

@ScottIsAFool too close but this functionality is not supported in the Mask :)
because the mask forces you to write a certain number of characters in the textbox and you can't exceed the limit.
Maybe we should think about a smart regex validator that can handle the decimal values a long with other regex validations.
I mean to create a more general validator, what do you think @ScottIsAFool @michaelcress ?

I think I have one of those written in an earlier project; I'll have to look. I shy away from regex these days because I find it aggravating and time-consuming to build and test the regex expressions. Therefore, I opted for hard-coding the logic to verify the decimal input. If the desire of the toolkit community is to have a more general purpose validation tool then regex is certainly one approach to solving that.

With respect to the code I have already written (decimal input validation), it is admittedly special purpose. However, its strict use case also makes the code easy to understand and use. That, to me, is the trade-off for the community to consider.

I've created a new issue so anyone can jump in and create the control #753
Will close this issue so we can focus on the new feature which will cover this behaviour.
