WPF Numeric UpDown 控件在哪里？

Where is the WPF Numeric UpDown control?

提问by AngryHacker

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. Was there an out of band release that I missed? Really don't feel like writing my own control.

进入第一个严肃的 WPF 项目。似乎缺少许多基本控件。具体来说，我正在寻找 Numeric UpDown 控件。有没有我错过的带外发行？真的不想写我自己的控件。

I do not want to use the WindowsFormHost and plop a WinForm ctl on it. I want it to be fully WPF without any legacy junk.

我不想使用 WindowsFormHost 并在它上面放一个 WinForm ctl。我希望它完全是 WPF，没有任何遗留垃圾。

Thanks

谢谢

Simply use the IntegerUpDowncontrol in the xtended wpf toolkitYou can use it like this:

只需使用xtended wpf 工具包IntegerUpDown中的控件就可以这样使用：

1. Add to your XAML the following namespace:

   xmlns:xctk="http://schemas.xceed.com/wpf/xaml/toolkit"

2. In your XAML where you want the control use:

   <xctk:IntegerUpDown Name="myUpDownControl" />

1. 将以下命名空间添加到 XAML：

   xmlns:xctk="http://schemas.xceed.com/wpf/xaml/toolkit"

2. 在您希望控件使用的 XAML 中：

   <xctk:IntegerUpDown Name="myUpDownControl" />

I made my own;

我自己做的；

xaml

<StackPanel Orientation="Horizontal">
    <TextBox x:Name="txtNum" x:FieldModifier="private" Margin="5,5,0,5" Width="50" Text="0" TextChanged="txtNum_TextChanged" />
    <Button x:Name="cmdUp" x:FieldModifier="private" Margin="5,5,0,5" Content="?" Width="20" Click="cmdUp_Click" />
    <Button x:Name="cmdDown" x:FieldModifier="private" Margin="0,5,0,5"  Content="?" Width="20" Click="cmdDown_Click" />
</StackPanel>

and the code behind

以及背后的代码

private int _numValue = 0;

public int NumValue
{
    get {  return _numValue; }
    set
    {
        _numValue = value;
        txtNum.Text = value.ToString();
    }
}

public NumberUpDown()
{
    InitializeComponent();
    txtNum.Text = _numValue.ToString();
}

private void cmdUp_Click(object sender, RoutedEventArgs e)
{
    NumValue++;
}

private void cmdDown_Click(object sender, RoutedEventArgs e)
{
    NumValue--;
}

private void txtNum_TextChanged(object sender, TextChangedEventArgs e)
{
    if (txtNum == null)
    {
        return;
    }

    if (!int.TryParse(txtNum.Text, out _numValue))
        txtNum.Text = _numValue.ToString();
}

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

这是我自己的带有向上和向下键捕获的 UserControl 的示例。

Xaml code:

Xml代码：

<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*" />
        <ColumnDefinition Width="13" />
    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions>
        <RowDefinition Height="13" />
        <RowDefinition Height="13" />
    </Grid.RowDefinitions>
    <TextBox Name="NUDTextBox"  Grid.Column="0" Grid.Row="0" Grid.RowSpan="2" TextAlignment="Right" PreviewKeyDown="NUDTextBox_PreviewKeyDown" PreviewKeyUp="NUDTextBox_PreviewKeyUp" TextChanged="NUDTextBox_TextChanged"/>
    <RepeatButton Name="NUDButtonUP"  Grid.Column="1" Grid.Row="0" FontSize="8" FontFamily="Marlett" VerticalContentAlignment="Center" HorizontalContentAlignment="Center" Click="NUDButtonUP_Click">5</RepeatButton>
    <RepeatButton Name="NUDButtonDown"  Grid.Column="1" Grid.Row="1" FontSize="8"  FontFamily="Marlett" VerticalContentAlignment="Center" HorizontalContentAlignment="Center" Height="13" VerticalAlignment="Bottom" Click="NUDButtonDown_Click">6</RepeatButton>
</Grid>

And the code:

和代码：

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 });

            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;

Use VerticalScrollBarwith the TextBlockcontrol in WPF. In your code behind, add the following code:

VerticalScrollBar与TextBlockWPF 中的控件一起使用。在后面的代码中，添加以下代码：

In the constructor, define an event handler for the scrollbar:

在构造函数中，为滚动条定义一个事件处理程序：

scrollBar1.ValueChanged += new RoutedPropertyChangedEventHandler<double>(scrollBar1_ValueChanged);
scrollBar1.Minimum = 0;
scrollBar1.Maximum = 1;
scrollBar1.SmallChange = 0.1;

Then in the event handler, add:

然后在事件处理程序中，添加：

void scrollBar1_ValueChanged(object sender, RoutedPropertyChangedEventArgs<double> e)
{
    FteHolderText.Text = scrollBar1.Value.ToString();
}

Here is the original snippet from my code... make necessary changes.. :)

这是我的代码的原始片段......进行必要的更改...... :)

public NewProjectPlan()

    InitializeComponent();

    this.Loaded += new RoutedEventHandler(NewProjectPlan_Loaded);

    scrollBar1.ValueChanged += new RoutedPropertyChangedEventHandler<double>(scrollBar1_ValueChanged);
    scrollBar1.Minimum = 0;
    scrollBar1.Maximum = 1;
    scrollBar1.SmallChange = 0.1;

    // etc...
}

void scrollBar1_ValueChanged(object sender, RoutedPropertyChangedEventArgs<double> e)

On MyPageDesign.xaml, drag and drop created usercontrol will having <UserControlTemplate:TemplateNumericUpDown HorizontalAlignment="Left" Height="100" VerticalAlignment="Top" Width="100"/>

在 MyPageDesign.xaml 上，拖放创建的用户控件将具有 <UserControlTemplate:TemplateNumericUpDown HorizontalAlignment="Left" Height="100" VerticalAlignment="Top" Width="100"/>

To get the value from the template, I use

为了从模板中获取值，我使用

string Value1 = JournalNumStart.NumValue;
string Value2 = JournalNumEnd.NumValue;

I'm not in good skill yet to binding the Height of the control based from FontSize element, so I set the from my page fontsize manually in usercontrol.

我还没有很好的技能来绑定基于 FontSize 元素的控件的高度，所以我在用户控件中手动设置了我的页面字体大小。

I have a naive solution but useful. Here is the code:

我有一个天真的解决方案，但很有用。这是代码：

<Grid Name="TVGrid" Background="#7F000000">  <ScrollBar Background="Black" Orientation="Vertical" Height="35" HorizontalAlignment="Left" Margin="215,254,0,0" Minimum="0" Maximum="10" LargeChange="10" Value="{Binding ElementName=channeltext2, Path=Text}" x:Name="scroll" VerticalAlignment="Top" Width="12" RenderTransformOrigin="0.5,0.5" ValueChanged="scroll_ValueChanged" >  
        <ScrollBar.RenderTransform>  
            <TransformGroup>  
                <ScaleTransform/>  
                <SkewTransform/>  
                <RotateTransform Angle="-180"/>  
                <TranslateTransform/>  
            </TransformGroup>  
        </ScrollBar.RenderTransform>  
    </ScrollBar>  
    <TextBox Name="channeltext" HorizontalContentAlignment="Center" FontSize="20"  Background="Black" Foreground="White" Height="35" HorizontalAlignment="Left" Margin="147,254,0,0" VerticalAlignment="Top" Width="53" Text="0" />  
    <TextBox Name="channeltext2" Visibility="Hidden" HorizontalContentAlignment="Center" FontSize="20"  Background="Black" Foreground="White" Height="35" HorizontalAlignment="Left" Margin="147,254,0,0" VerticalAlignment="Top" Width="53" Text="0" />  </Grid>
