    Hi,

    I need to restrict - signs in numericupdown control. I want to allow entering only positive integer. Using minvalue = 0 is not good since it resets to 0 only when control looses focus. But if control used in wizard, and user clicks "OK" he will not notice that -100 he entered actually saved as 0.

    Is there any thoughts?
    Right now I am not using MinValue, but instead validating on ViewModel. So if user enters -100 user will see validation error. It would be more user friendly if I could just restrict incorrect values.

    Thanks, Alexey.

    Hello Alexey,

    Thank you for contacting us.

    Unfortunately, there is no build in way to restrict entering wrong values in the NumericUpDown control.
    The validation approach you chose is the best one in this scenario.

    If you have any other questions about our controls please feel free to contact us again.
