If using the Syncfusion library is possible, an IntegerTextBox which uses arrow buttons to in-/decrease the value could be used. Minimal and maximal values can be defined in this element too.

<Window x:Class="ConTecBrowser.Example"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:syncfusion="http://schemas.syncfusion.com/wpf"
        mc:Ignorable="d"
        Title="Example" Height="450" Width="800">
    <Grid>
        <syncfusion:IntegerTextBox ShowSpinButton="True" MinValue="1"/>
    </Grid>
</Window>

The texbox in WPF

 <TextBox Name="textbox1" HorizontalAlignment="Left" Text="0" Height="23" TextWrapping="Wrap" VerticalAlignment="Top" Width="120" Margin="154,138,0,0" PreviewKeyDown="TextBox_KeyDown"/>

CodeBehind

private void TextBox_KeyDown(object sender, KeyEventArgs e)
{
    int currentNumber = Convert.ToInt32(textbox1.Text);
    if (e.Key == Key.Up)
    {

        textbox1.Text = (currentNumber + 1).ToString();
    }
    else if (e.Key == Key.Down)
    {
        textbox1.Text = (currentNumber - 1).ToString();
    }
}
