ValueChanged - RadNumericUpDown vs RadMaskedNumericInput

[Przemyslaw]

Hello,

The RadMaskedNumericInput.ValueChanged event is only fired after a user-triggered action, whereas RadNumericUpDown.ValueChanged not (changing value from code behind triggers this event aswell).

Does this difference is a desired behavior? Is there a possibility to make RadNumericUpDown act like RadMaskedNumericInput?

Please see code sample below.

    public partial class MainView : Window
    {
        public MainView()
        {
            InitializeComponent();
            RadNumericUpDownTest.ValueChanged += RadNumericUpDownTestOnValueChanged;
            RadMaskedNumericInputTest.ValueChanged+=RadMaskedNumericInputTestOnValueChanged;
            UpdateButton.Click+=UpdateButtonOnClick;
        }

        private void UpdateButtonOnClick(object sender, RoutedEventArgs routedEventArgs)
        {
            RadNumericUpDownTest.Value = 1;
            RadMaskedNumericInputTest.Value = 1;
        }

        private void RadNumericUpDownTestOnValueChanged(object sender, RadRangeBaseValueChangedEventArgs radRangeBaseValueChangedEventArgs)
        {
            //This event is triggered after value is changed from code behind
        }


        private void RadMaskedNumericInputTestOnValueChanged(object sender, RadRoutedEventArgs radRoutedEventArgs)
        {
            //This event is not triggered after value is changed from code behind
        }
    }

Hello Przemyslaw,

Thank you for your interest in our RadNumericUpDown control for WPF.

The RadMaskedTextInput.ValueChanged event is only fired after a user-triggered action. As changing the value of the control in code-behind isn't considered a user-triggered interaction, the event handler is never executed.

The RadNumericUpDown.ValueChanged event will be fired when a user changed the value or the value is changed programmatically. This is the default behavior on both controls. What I can suggest to you at this moment for the RadNumericUpDown control is to create a flag when you update the value from code behind. This way you will know whether the value is changed from the user input or not.
