我在我的项目中包含了这个用户控件。但是在 Wpf 应用程序中实现 UserControl 时，我的 UserControl 没有单击事件。所以我将 Click="UserControl1_Click" 添加到 Xaml。但它通过一个错误
The property 'Click' does not exist in XML namespace 'clr-namespace:NumericTextbox;assembly=NumericTextbox'.
XML 命名空间“clr-namespace:NumericTextbox;assembly=NumericTextbox”中不存在属性“Click”。
My Application Xaml Code-
我的应用程序 Xaml 代码 -
<Window x:Class="NumericAppication.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:NumText="clr-namespace:NumericTextbox;assembly=NumericTextbox"
Title="MainWindow" Height="350" Width="525">
<Grid>

As we have created the UserControl1.then after adding the Click event the UserControl1.Desginer.cs file will look like this.
由于我们已经创建了 UserControl1.then，在添加 Click 事件后，UserControl1.Desginer.cs 文件将如下所示。
private void InitializeComponent()
{
this.button1 = new System.Windows.Forms.Button();
this.SuspendLayout();
//
// button1
//
this.button1.Location = new System.Drawing.Point(180, 38);
this.button1.Name = "button1";
this.button1.Size = new System.Drawing.Size(75, 23);
this.button1.TabIndex = 0;
this.button1.Text = "button1";
this.button1.UseVisualStyleBackColor = true;
this.button1.Click += new System.EventHandler(this.button1_Click);
//
// UserControl1
//
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.Controls.Add(this.button1);
this.Name = "UserControl1";
this.Size = new System.Drawing.Size(286, 95);
this.ResumeLayout(false);
}
and in the UserControl1.cs file will have the body of the Button click event
并且在 UserControl1.cs 文件中会有按钮点击事件的主体
private void button1_Click(object sender, EventArgs e)
{
}
this may help you.Plz let me know
这可能对你有帮助。请告诉我

You could have a Dependency Property on the UserControl that you bind to the Click event of the button.
您可以在绑定到按钮的 Click 事件的 UserControl 上有一个依赖属性。
EDIT:
编辑：
In your UserControl you can have
在您的 UserControl 中，您可以拥有
public EventHandler MyProperty
{
get { return (EventHandler)GetValue(MyPropertyProperty); }
set { SetValue(MyPropertyProperty, value); }
}
public static readonly DependencyProperty MyPropertyProperty = DependencyProperty.Register("MyProperty", typeof(EventHandler), typeof(ownerclass));
then in the XAML you have:
然后在 XAML 中你有：
<button Click="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}, Path=MyProperty}" />
Although, I think that it is best practice to use ICommand instead of the event handler but the principle is the same.
虽然，我认为最好使用 ICommand 而不是事件处理程序，但原理是相同的。

You can create a command an make a command binding like this:
您可以像这样创建命令并进行命令绑定：
Create RoutedUiCommand command:
创建 RoutedUiCommand 命令：
Class Command
{
Static RoutedUICommand ButtonClick = New RoutedUICommand("Buttonclick", "ButtonClick", TypeOf(Window))
}
Then in xaml
然后在xaml
<Window.CommandBindings>
<CommandBinding Command="local:Command.ButtonClick" Executed="CommandBinding_ButtonClick" />
</Window.CommandBindings>
inside the method CommandBinding_ButtonClickyou make the logic.
在CommandBinding_ButtonClick你制作逻辑的方法中。
and finally add the command to the button:
最后将命令添加到按钮：
<Button Style="{StaticResource ButtonWithoutHover}" Height="25" Width="20" BorderThickness="3" BorderBrush="White" DockPanel.Dock="Right" Background="CadetBlue" Command=local:Command.ButtonClick>
<Button.Content>
<Label Content="->" Foreground="White" />
</Button.Content>
</Button>

When you design your user control have you tried this on your button? (remember to choose that edit template thing)
当你设计你的用户控件时，你有没有在你的按钮上试过这个？（记得选择那个编辑模板的东西）

p.s. when I design user controls I always prefer to use blend.
ps 当我设计用户控件时，我总是更喜欢使用混合。
