From your elaboration I understand that you need multiple validation. Once when the user insert or replace the digits in the RadMaskedNumericInput
control and one more time when the user submits your form.
Please note that the first validation should be triggered by the PropertyChanged
event by default. Hence, if you set the UpdateValueEvent
property of the RadMaskedNumericInput
the control will trigger the validation on every change of the Value
Another way to achieve the same is to trigger your custom validation in the setter of the property defined in your ViewModel.
I hope that this clarifies everything.
