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.
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.
Thanks
This question is related to

updown
The answer is
Simply use the IntegerUpDown control in the Extended.Wpf.Toolkit
You can use it like this:
Add to your XAML the following namespace:
xmlns:xctk="http://schemas.xceed.com/wpf/xaml/toolkit"In your XAML where you want the control use:
<xctk:IntegerUpDown Name="myUpDownControl" />
<ResourceDictionary

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:-

{
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 =)
Let's enjoy some hacky things:
Here is a Style of Slider as a NumericUpDown, simple and easy to use, without any hidden code or third party library.

I have a naive solution but useful. Here is the code:
<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>
I made my own;
the 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
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();
}
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:

Here is another open source control that has many different input methods (mouse drag, mouse wheel, cursor keys, textbox editing), supports many data types and use cases:
You can use NumericUpDown control for WPF written by me as a part of WPFControls library.
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 :)
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();
}
This is example of my own UserControl with Up and Down key catching.
Xaml code:
<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:
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;
}
}
Go to NugetPackage manager of you project-> Browse and search for mahApps.Metro -> install package into you project. You will see Reference added: MahApps.Metro. Then in you XAML code add:
"xmlns:mah="http://metro.mahapps.com/winfx/xaml/controls"
Where you want to use your object add:
<mah:NumericUpDown x:Name="NumericUpDown" ... />
Enjoy the full extensibility of the object (Bindings, triggers and so on...).
