KeyDown 事件不会使用 Enter 键在 ContextMenuStrip 上触发? [英] KeyDown event doesn't fire on ContextMenuStrip with enter key?

问题描述

.NET:我有一个上下文菜单条，我想使用键盘键来处理.

.NET : I have a Context menu strip that I want to handle using keyboard keys.

我有以下事件处理程序:

I have the following event handler:

Private Sub ContextMenuEnterKey(ByVal Sender As Object, ByVal E As KeyEventArgs) Handles ContextMenu.KeyDown

    If E.KeyValue = Keys.Enter Then
        'Do some staff
    End If

End Sub

使用除 EnterKey 以外的其他键可以正确触发事件.

The events fires correctly with other keys except EnterKey.

有人知道这是怎么回事吗?

Does anyone know what's wrong with that ?

推荐答案

您将处理程序绑定到哪个控件的 KeyDown 事件?在表单设计器中?KeyDown 事件甚至没有为 ContextMenuStrip 显示(至少在 VS2012 中，我正在使用 C#...)我可以在代码中绑定到 in，但是这似乎没有任何影响.

To which control's KeyDown event are you binding your handler? In the Forms designer the ? KeyDown event isn't even shown for ContextMenuStrip (at least here in VS2012, and I'm working in C#...) I can bind to in in code, but this doesn't seem to have any effect.

但是在 ContextMenuStrip 中有一个 PreviewKeyDown 事件，它会在上下文菜单中的每次击键时调用，也为 Enter 键调用.也许这可以帮助您?

But there is a PreviewKeyDown event in ContextMenuStrip which gets called for every keystroke within the context menu, also for the Enter key. Maybe this can help you?
