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
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" />
I made my own;
the xaml
<Grid Height="23" Margin="152,63,11,0" VerticalAlignment="Top">
<TextBox x:Name="txtNum" x:FieldModifier="private" Text="0" TextChanged="txtNum_TextChanged" Margin="3,2,13,3" />
<Button x:Name="cmdUp" x:FieldModifier="private" FontSize="10" Padding="0,-4,0,0" Content="▲" Width="10" Click="cmdUp_Click" Margin="33,2,1,13" />
<Button x:Name="cmdDown" x:FieldModifier="private" FontSize="10" Padding="0,-4,0,0" Content="▼" Width="10" Click="cmdDown_Click" Margin="33,12,1,3" />
</Grid>
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();
}
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;
}
}

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

public partial class TemplateNumericUpDown : UserControl

public TemplateNumericUpDown()
{

}

txtNum.Text = value.ToString();
}
}
}

{
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 =)
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.

If you want apply input restrictions on TextBox indeed, try this:
public static class InputLimit
{
public static string GetDecimalValueProxy(TextBox obj) => (string)obj.GetValue(DecimalValueProxyProperty);
public static void SetDecimalValueProxy(TextBox obj, string value) => obj.SetValue(DecimalValueProxyProperty, value);
// Using a DependencyProperty as the backing store for DecimalValueProxy. This enables animation, styling, binding, etc...
public static readonly DependencyProperty DecimalValueProxyProperty =
DependencyProperty.RegisterAttached("DecimalValueProxy", typeof(string), typeof(InputLimit),
new FrameworkPropertyMetadata("0", FrameworkPropertyMetadataOptions.BindsTwoWayByDefault, null, CoerceDecimalValueProxy));
private static object CoerceDecimalValueProxy(DependencyObject d, object baseValue)
{
if (decimal.TryParse(baseValue as string, out _)) return baseValue;
return DependencyProperty.UnsetValue;
}
}
And modify xaml TextBox part to:
<TextBox Grid.RowSpan="2" Height="Auto"
Margin="0" Padding="0"
VerticalAlignment="Stretch" VerticalContentAlignment="Center"
local:InputLimit.DecimalValueProxy="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, Path=Value}"
Text="{Binding RelativeSource={RelativeSource Self}, Path=(local:InputLimit.DecimalValueProxy), UpdateSourceTrigger=PropertyChanged}">
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>
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 :)

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...).
