I'm using UpDown and I need configure the validation when a new value is entered.

By default, binded property is immediately updated when a key is pressed.
But I need something like LostFocus validation for the current value.

Furthermore, validation must be active on up/down buttons.

Is that possible?

Hi Marijan,


We have prepared a sample based on your requirement. In that we have validated the input value 20 in the lost focus and also in value changed by the repeat button of updown.

Please find the attached sample below.
