编辑 1:

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

I have include this Usercontrol in My project. But at the time of Implementing UserControl in Wpf Application There is No Click Event for my UserControl. So I add Click="UserControl1_Click" to Xaml. But It through an Error

XML 命名空间中不存在属性Click"'clr-namespace:NumericTextbox;assembly=NumericTextbox'.

The property 'Click' does not exist in XML namespace 'clr-namespace:NumericTextbox;assembly=NumericTextbox'.

我的应用程序 Xaml 代码-

My Application Xaml Code-

<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>
        <NumText:UserControl1 Width="120" Height="30" Click="UserControl1_Click" />
    </Grid>
</Window>

推荐答案

因为我们已经创建了 UserControl1.然后在添加 Click 事件之后 UserControl1.Desginer.cs 文件将如下所示.

As we have created the UserControl1.then after adding the Click event the UserControl1.Desginer.cs file will look like this.

  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);

        }

并且在 UserControl1.cs 文件中会有按钮点击事件的主体

and in the UserControl1.cs file will have the body of the Button click event

private void button1_Click(object sender, EventArgs e)
        {

        }

这可能对你有帮助.请告诉我
