我在自定义控件中有一个组合框.如何将其中的特定事件(例如 SelectedIndexChanged 或 KeyPress 等)公开给实现我的自定义控件的任何人/事物?

I have a combobox in a custom control. How can I expose specific events from it such as SelectedIndexChanged or KeyPress, etc to anyone/thing implementing my custom control?

推荐答案

你可以这样转发事件:

    public event EventHandler SelectedIndexChanged 
    {
        add { inner.SelectedIndexChanged += value; }
        remove { inner.SelectedIndexChanged -= value; }
    }
