底层控制的暴露事件 [英] Exposing events of underlying control

问题描述

我有一个自定义的控制组合框。我如何可以公开从它特定的事件，如的SelectedIndexChanged或按键等任何人/事实现我的自定义控制？

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

您可以将事件转发如下：

You can forward the events like this:

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