NumericUpDown can not bind Value

Apr 18, 2013 at 2:47 AM
NumericUpDown seems to be unable to bind, e.g. the following code won't work
<ctrl:NumericUpDown Value="{Binding Attack}" /> 
but if you change NumericUpDown to Slider, it works
<Slider Value="{Binding Attack}"/>
what am I missing?

oh, just found it need to set Mode=TwoWay to make it work, but Slider don't need this.

why don't NumericUpDown behave like other RangeBase controls?
