This is my first time using the masked input and I could use some help. I don't want the placeholder, so I'm using Mask="". In this example, I want to restrict to positive integers only (or blank if it's an optional input). I can restrict the numeric version to digits only, but how do I prevent the negative sign?
I would actually prefer to use the normal masked input and simply limit it to the characters 0-9. However when I use Mask="", I have not been able to restrict the inputs using the FormatString. It's still allowing me to type anything.
