问题描述

当组合框处于活动状态时，如何在Windows窗体组合框中捕获回车键？

How do I capture the enter key in a windows forms combo box when the combobox is active?

我试图监听KeyDown和KeyPress，

I've tried to listen to KeyDown and KeyPress and I've created a subclass and overridden ProcessDialogKey, but nothing seems to work.

有没有想法？

推荐答案

将KeyPress事件挂钩到这样的方法：

Hook up the KeyPress event to a method like this:

protected void myCombo_OnKeyPress(object sender, KeyPressEventArgs e)
{
    if (e.KeyChar == 13)
    {
        MessageBox.Show("Enter pressed", "Attention");                
    }
}

我在WinForms应用程序它的工作原理。

I've tested this in a WinForms application with VS2008 and it works.
