c# winform 用户控件usercontrol 事件在父窗体触发

User control:

[Browsable(true)] [Category("Action")] 
[Description("调用用户按钮事件")]
public event EventHandler ButtonClick;

protected void Button1_Click(object sender, EventArgs e)
{
    //bubble the event up to the parent
    if (this.ButtonClick!= null)
        this.ButtonClick(this, e);               
}




Form:

UserControl1.ButtonClick += new EventHandler(UserControl_ButtonClick);

protected void UserControl_ButtonClick(object sender, EventArgs e)
{
    //handle the event 
}

推荐一种更简洁的方法

UserControl:
public System.Windows.Forms.Panel panel;



Winform：
UserControl item = new UserControl();
item.panelTitle.Click += panel1_Click;

protected void panel1_Click(object sender, EventArgs e)
{
   var form = (UserControl)(((Panel)sender).Parent);
   Method(sender, e);
}
