推荐答案

根据 IntegerUpDown ，没有允许您想要的内容，您可以尝试使用Usercontrol.以下是一个简单的示例.

According to the IntegerUpDown, there is no property to allow what you want , you can try the Usercontrol. the following is a simple sample.

<UserControl x:Class="wpfAppDemo.wpfUserControl.IntegerUp"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:local="clr-namespace:wpfAppDemo.wpfUserControl"
             mc:Ignorable="d" 
             d:DesignHeight="30" d:DesignWidth="250">

        <UserControl.Resources>
            <ControlTemplate x:Key="IntegerUp" TargetType="ContentControl">               
                <StackPanel Orientation="Horizontal">
                <TextBox x:Name="UpTextBox" Height="20" Width="200" HorizontalAlignment="Center" TextAlignment="Right"/>
                <Button x:Name="UpButton" Height="20" Width="40" Margin="0,0,0,0" Click="UpButton_Click">
                    <Canvas Width="40" Height="20" Clip="F1 M 0,0L 76,0L 76,76L 0,76L 0,0">
                        <Path Canvas.Left="11" Width="18" Height="18" Stretch="Fill"
              Fill="{Binding Foreground, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=Button}}"
              Data="F1 M 35,19L 41,19L 41,35L 57,35L 57,41L 41,41L 41,57L 35,57L 35,41L 19,41L 19,35L 35,35L 35,19 Z">
                        </Path>
                    </Canvas>
                    <Button.Style>
                        <Style TargetType="Button">
                            <Style.Triggers>
                                <Trigger Property="IsMouseOver" Value="True">
                                    <Setter Property="Foreground" Value="Red" />
                                </Trigger>
                                <Trigger Property="IsMouseOver" Value="False">
                                    <Setter Property="Foreground" Value="Gray" />
                                </Trigger>
                            </Style.Triggers>
                        </Style>
                    </Button.Style>
                </Button>
            </StackPanel>
            </ControlTemplate>
        </UserControl.Resources>
    <ContentControl Height="30" x:Name="UpContentControl" Template="{StaticResource IntegerUp}"></ContentControl>
</UserControl>

public partial class IntegerUp : UserControl
    {
        public IntegerUp()
        {
            InitializeComponent();
        }

        private void UpButton_Click(object sender, RoutedEventArgs e)
        {
            TextBox textBox = UpContentControl.Template.FindName("UpTextBox", UpContentControl) as TextBox;
            int val;
            if (int.TryParse(textBox.Text, out val))
            {
                val++;
                textBox.Text = val.ToString();
            }
        }
    }

希望这对您有所帮助.
