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

    Simply use the IntegerUpDown control in the xtended wpf toolkit You can use it like this:

    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" />

    You can use NumericUpDown control for WPF written by me as a part of WPFControls library.

    Use VerticalScrollBar with the TextBlock control in WPF. In your code behind, add the following code:

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

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

    Then in the event handler, add:

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

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

    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)
    {
        FteHolderText.Text = scrollBar1.Value.ToString();
    }

    Apologize for keep answering 9 years questions.

    I have follow @Michael's answer and it works.

    I do it as UserControl where I can drag and drop like a Controls elements. I use MaterialDesign Theme from Nuget to get the Chevron icon and button ripple effect.

    The running NumericUpDown from Micheal with modification will be as below:-

    The code for user control:-

    TemplateNumericUpDown.xaml

    <UserControl x:Class="UserControlTemplate.TemplateNumericUpDown"
                 xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                 xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

                 xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
                 xmlns:local="clr-namespace:UserControlTemplate"
                 xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"
                 mc:Ignorable="d" MinHeight="48">
        <Grid Background="{DynamicResource {x:Static SystemColors.WindowFrameBrushKey}}">
            <Grid.ColumnDefinitions>
                <ColumnDefinition/>
                <ColumnDefinition Width="60"/>
            </Grid.ColumnDefinitions>
            <TextBox x:Name="txtNum" x:FieldModifier="private" Text="{Binding Path=NumValue}" TextChanged="TxtNum_TextChanged" FontSize="36" BorderThickness="0" VerticalAlignment="Center" Padding="5,0"/>

                <Grid Background="#FF673AB7">
                    <Viewbox HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Height="Auto" Width="Auto">
                        <materialDesign:PackIcon Kind="ChevronUp" Foreground="White" Height="32.941" Width="32"/>
                    </Viewbox>
                    <Button x:Name="cmdUp" x:FieldModifier="private" Click="CmdUp_Click" Height="Auto" BorderBrush="{x:Null}" Background="{x:Null}"/>
                </Grid>
                <Grid Grid.Row="1" Background="#FF673AB7">
                    <Viewbox HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Height="Auto" Width="Auto">
                        <materialDesign:PackIcon Kind="ChevronDown" Foreground="White" Height="32.942" Width="32"/>
                    </Viewbox>
                    <Button x:Name="cmdDown" x:FieldModifier="private" Click="CmdDown_Click" Height="Auto" BorderBrush="{x:Null}" Background="{x:Null}"/>
                </Grid>
            </Grid>
        </Grid>
    </UserControl>
    

    TemplateNumericUpDown.cs

    using System.Windows;
    using System.Windows.Controls;
    
    namespace UserControlTemplate
    {
        /// <summary>
        /// Interaction logic for TemplateNumericUpDown.xaml
        /// </summary>
        public partial class TemplateNumericUpDown : UserControl
        {
            private int _numValue = 0;
            public TemplateNumericUpDown()
            {
                InitializeComponent();
                txtNum.Text = _numValue.ToString();
            }
            public int NumValue
            {
                get { return _numValue; }
                set
                {
                    if (value >= 0)
                    {
                        _numValue = value;
                        txtNum.Text = value.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();
            }
        }
    }
    

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

    To get the value from the template, I use

    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.

    ** Note:- I have change the "Archieve" name to Archive on my program =)

    Just a pragmatic to do sample:

    -Right click your Project (under Solution), select "Manage nuget Packages..."

    -In Menu click Browse Tab search for "wpftoolkit", select "Extended.Wpf.Toolkit"

    -Install it!

    -Right click in your User Control Toolbox, select "Add Tab.." and name it "WPF Toolkit"

    -Right click on the new "WPF Toolkit" Tab, select "Choose items..."

    -In Menu click "Browse..." Button, look for nugets DLL folder, select all "...\packages\Extended.Wpf.Toolkit.3.5.0\lib\net40\*.dll"

    Ignore Warnings about some DLLs may not containing user controls!

    Ready :)

    The given answers are OK. However, I wanted the buttons to auto hide, when mouse leave the control. Here is my code based on vercin answer above:

    Style

    <Style TargetType="{x:Type v:IntegerTextBox}">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type v:IntegerTextBox}">

                            </Grid.RowDefinitions>
                            <Grid.ColumnDefinitions>
                                <ColumnDefinition Width="*"/>
                                <ColumnDefinition Width="Auto"/>
