进入第一个严肃的 WPF 项目。似乎缺少很多基本控件。具体来说，我正在寻找 Numeric UpDown 控件。有没有我错过的带外版本？真的不想写自己的控件。
我不想使用 WindowsFormHost 并在其上添加一个 WinForm ctl。我希望它完全是 WPF，没有任何遗留垃圾。
谢谢

只需使用Extended.Wpf.ToolkitIntegerUpDown中的控件
就可以这样使用：
将以下命名空间添加到您的 XAML：
xmlns:xctk="http://schemas.xceed.com/wpf/xaml/toolkit"在您希望控件使用的 XAML 中：
<xctk:IntegerUpDown Name="myUpDownControl" />

我自己做的；
xml
<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>
和背后的代码
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++;
}

txtNum.Text = _numValue.ToString();

让我们享受一些 hacky 的东西：

</Border>

TextBox如果您想对确实应用输入限制，请尝试以下操作：
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;
}
}
并将 xamlTextBox部分修改为：
<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}">

VerticalScrollBar与TextBlockWPF 中的控件一起使用。在后面的代码中，添加以下代码：
在构造函数中，为滚动条定义一个事件处理程序：
scrollBar1.ValueChanged += new RoutedPropertyChangedEventHandler<double>(scrollBar1_ValueChanged);
scrollBar1.Minimum = 0;
scrollBar1.Maximum = 1;
scrollBar1.SmallChange = 0.1;
然后在事件处理程序中，添加：
void scrollBar1_ValueChanged(object sender, RoutedPropertyChangedEventArgs<double> e)
{
FteHolderText.Text = scrollBar1.Value.ToString();
}
这是我的代码的原始片段...进行必要的更改.. :)
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();
}

为继续回答 9 年的问题而道歉。
我已经遵循@Michael 的回答并且它有效。

</Grid>
</Grid>
</Grid>
</UserControl>
TemplateNumericUpDown.cs
using System.Windows;
using System.Windows.Controls;
namespace UserControlTemplate
{
/// <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();
}
}
}
在 MyPageDesign.xaml 上，拖放创建的用户控件将具有<UserControlTemplate:TemplateNumericUpDown HorizontalAlignment="Left" Height="100" VerticalAlignment="Top" Width="100"/>
为了从模板中获取值，我使用
string Value1 = JournalNumStart.NumValue;
string Value2 = JournalNumEnd.NumValue;
我还没有很好的技能来绑定基于 FontSize 元素的控件的高度，所以我在用户控件中手动设置了我的页面字体大小。
** 注意：- 我已在我的程序中将“Archieve”名称更改为 Archive =)

只是一个务实的样本：
-右键单击您的项目（在解决方案下），选择“管理 nuget 包...”
- 在菜单中单击浏览选项卡搜索“wpftoolkit”，选择“ Extended.Wpf.Toolkit”
- 安装它！
-右键单击您的用户控件工具箱，选择“添加选项卡..”并将其命名为“WPF Toolkit”
-右键单击新的“WPF Toolkit”选项卡，选择“Choose items...”
- 在菜单中单击“浏览...”按钮，查找 nugets DLL 文件夹，全选“ ...\packages\Extended.Wpf.Toolkit.3.5.0\lib\net40\*.dll”
忽略有关某些 DLL 可能不包含用户控件的警告！

在你想使用你的对象的地方添加：
