Answer 1

因此，您希望在单击子面板时在父面板上触发click事件。

我可以想到两种方法可以做到这一点。

第一种方法是从Panel2的Click事件处理程序方法中简单地调用Panel1的Click事件处理程序方法：

private void panel1_Click(object sender, EventArgs e)
{
    MessageBox.Show("Panel 1 clicked.");
}

private void panel2_Click(object sender, EventArgs e)
{
    this.panel1_Click(sender, e);
}

可能更好的方法是将两个点击事件都注册到1处理程序方法：

private void panel1_Click(object sender, EventArgs e)
{
    MessageBox.Show("Panel 1 clicked.");
}

然后从表单设计器或手动注册第二个面板的事件：

this.panel2.Click += new System.EventHandler(this.panel1_Click);

C＃make父面板处理所有事件
