Where is the WPF Numeric UpDown control?

Question

Getting into the first serious WPF project. It seems like there are a lot of basic controls flat out missing. Specifically, I am looking for the Numeric UpDown control. W

Answer 1

This is example of my own UserControl with Up and Down key catching.

Xaml code:

    
        
        
    
    
        
        
    
    
    5
    6

And the code:

public partial class NumericUpDown : UserControl
{
    int minvalue = 0, 
        maxvalue = 100,
        startvalue = 10;
    public NumericUpDown()
    {
        InitializeComponent();
        NUDTextBox.Text = startvalue.ToString();
    }

    private void NUDButtonUP_Click(object sender, RoutedEventArgs e)
    {
        int number;
        if (NUDTextBox.Text != "") number = Convert.ToInt32(NUDTextBox.Text);
        else number = 0;
        if (number < maxvalue)
            NUDTextBox.Text = Convert.ToString(number + 1); 
    }

    private void NUDButtonDown_Click(object sender, RoutedEventArgs e)
    {
        int number;
        if (NUDTextBox.Text != "") number = Convert.ToInt32(NUDTextBox.Text);
        else number = 0;
        if (number > minvalue)
            NUDTextBox.Text = Convert.ToString(number - 1); 
    }

    private void NUDTextBox_PreviewKeyDown(object sender, KeyEventArgs e)
    {

        if (e.Key == Key.Up)
        {
            NUDButtonUP.RaiseEvent(new RoutedEventArgs(Button.ClickEvent));
            typeof(Button).GetMethod("set_IsPressed", BindingFlags.Instance | BindingFlags.NonPublic).Invoke(NUDButtonUP, new object[] { true }); 
        }


        if (e.Key == Key.Down)
        {
            NUDButtonDown.RaiseEvent(new RoutedEventArgs(Button.ClickEvent));
            typeof(Button).GetMethod("set_IsPressed", BindingFlags.Instance | BindingFlags.NonPublic).Invoke(NUDButtonDown, new object[] { true }); 
        }
    }

    private void NUDTextBox_PreviewKeyUp(object sender, KeyEventArgs e)
    {
        if (e.Key == Key.Up)
            typeof(Button).GetMethod("set_IsPressed", BindingFlags.Instance | BindingFlags.NonPublic).Invoke(NUDButtonUP, new object[] { false });

        if (e.Key == Key.Down)
            typeof(Button).GetMethod("set_IsPressed", BindingFlags.Instance | BindingFlags.NonPublic).Invoke(NUDButtonDown, new object[] { false });
    }

    private void NUDTextBox_TextChanged(object sender, TextChangedEventArgs e)
    {
        int number = 0;
        if (NUDTextBox.Text!="")
            if (!int.TryParse(NUDTextBox.Text, out number)) NUDTextBox.Text = startvalue.ToString();
        if (number > maxvalue)  NUDTextBox.Text = maxvalue.ToString();
        if (number < minvalue) NUDTextBox.Text = minvalue.ToString();
        NUDTextBox.SelectionStart = NUDTextBox.Text.Length;

    }
