从表单到用户控件的单击事件处理

Question

大家好，我想问一下如何转发事件处理程序来点击动态生成按钮。这个按钮我生成到 Form1.cs 中的 flowlayout 面板 我在有 2 个按钮的地方生成用户控件“btnMini.cs”。 如何将这些按钮的单击事件从 Form1 转发到 UserControl - “btnMini.cs”？ 我想在单击按钮转发并获取 messagebox.show 之后“按钮的父名称”在哪里，其他显示“按钮名称”。我怎样才能从 Form1 中做到这一点？

Button btn = (Button)sender;
MessageBox.Show("button name: " + btn.Name + ", Parent name control: " + btn.Parent.Name);

我试试这个，但是当我需要在单击后在 Form1 中创建 MessageBox.Show 时，我不知道该怎么做。... 谢谢你的建议？？？？？？？？。我有点绝望：/所以非常感谢身体的提示。 代码：

public partial class btnMini : UserControl
{
    public btnMini()
    {
        InitializeComponent();
    }
    
    [Browsable(true)]
    [Category("ActionClick")]
    [Description("Invoke when user clicks on button")]
    public event EventHandler ButtonClick;//ok
   
    private void TestingClicks(object sender, EventArgs e)
    {
        ButtonClick?.Invoke(sender, e);
    }
    
    public void OnClick(object sender, EventArgs e)
    {
        TestingClicks(sender, e);           
    }
}

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }
    
    #region variables
    
    private int counter = 1;
    private btnMini btnM = new btnMini();
    private List<Control> control = new List<Control>();
    
    //public event EventHandler ClickTest;
    
    #endregion

    //Using this method I adding userControl to list
    private void button1_Click(object sender, EventArgs e)
    {
        //Button btn = (Button)sender;
        //MessageBox.Show("Click btn: " + btn.Name + ", Parent name control: " + btn.Parent.Name); //Here I tried do this for get Name of parent and button UserControl - btnMini.cs

        btnM = new btnMini();
        btnM.Name = "btn_" + counter;
        btnM.Click += (s, ev) =>
        {
            Button b = (Button)sender;
            //string parent = button?.Parent?.Name;
            MessageBox.Show(b.Name.ToString());
        };
        counter++;
        control.Add(btnM);
    }
    
    //method for adding UserControl from List.
    private void button2_Click(object sender, EventArgs e)
    {
        foreach (var b in control)
        {
            this.flowLayoutPanel1.Controls.Add(b);
        }
    }
}

Answer 1

btnM.ButtonClick += (sender, e) =>
{
    Button btn = (Button)sender;
    MessageBox.Show("Parent name: " + btn.Parent.Name + ", button name: " + btn.Name);
};

经过测试和玩代码终于可以工作了。
