I need check user input data for control from User Interface. I usually IsFocused properties, but when user click on button Up/Down of control RadNumbericUpDown then IsFocused = false
How to check event ValueChanged if Up/Down Button is pressed on NumericUpDown Control ??
The Value of RadNumericUpDown is updated on losing focus by default, so the ValueChanged event is triggered then as well. However there is a way to change when the Value is updated. Just set : UpdateValueEvent="PropertyChanged". This will update the Value on every keystroke.
