c# - WPF/C# - 向列表框中动态创建的按钮添加功能

Question

我有一个按钮，每次单击它时都会将此 StackPanel 添加到列表框。里面有一个按钮。我试图弄清楚如何将代码添加到它正在添加的这个按钮。理想情况下，我希望该按钮是一个删除按钮，这样它就会删除列表中的那个元素(本身)。我只是想弄清楚如何向我动态创建的按钮添加功能。希望这是有道理的

感谢您的帮助!

    private void Button_Click_1(object sender, RoutedEventArgs e)
    {
        StackPanel stackPanel = new StackPanel();
        stackPanel.Orientation = System.Windows.Controls.Orientation.Horizontal;

        CheckBox checkBox = new CheckBox();
        checkBox.IsChecked = true;

        TextBox textBox = new TextBox();
        textBox.Width = 100;
        textBox.Text = textBox1.Text;

        Button button = new Button();  //HOW DO I ADD CODE TO THIS BUTTON?

        stackPanel.Children.Add(checkBox);
        stackPanel.Children.Add(textBox);
        stackPanel.Children.Add(button);  //HOW DO I ADD CODE TO THIS BUTTON?

        listBox1.Items.Add(stackPanel);
    }

您可以像这样以编程方式向按钮添加点击处理程序:

    Button button = new Button();  //HOW DO I ADD CODE TO THIS BUTTON?
    button.Click += btn_Click;

    stackPanel.Children.Add(checkBox);
    stackPanel.Children.Add(textBox);
    stackPanel.Children.Add(button);  //HOW DO I ADD CODE TO THIS BUTTON?

然后你需要点击事件处理器

    void btn_Click(object sender, System.Windows.RoutedEventArgs e)
    {
        // your code to execute when the button is clicked.
        stackPanel.Items.Remove(button);
    }
