推荐答案

使用这些事件：


Private Sub Button1_GotFocus（ByVal sender As Object，ByVal e As

System.EventArgs）处理Button1.GotFocus

Button1.BackColor = .....

End Sub

Private Sub Button1_LostFocus（ByVal发送者作为对象，ByVal e As

System.EventArgs）处理Button1.LostFocus

Button1.BackColor = .....

End Sub

希望它有所帮助

Stefan，

克里斯建议你可以使用GotFocus& LostFocus事件为此。


为了尽量减少重复的代码，我会考虑使用：

1.所有控件的单个事件处理程序

2.派生控件

3.一个ExtenderProvider（实现System.Component.IExtenderProvider）


＃1你需要添加相同的处理程序在每个表单上，加上将所有

控件连接到处理程序。


使用＃2，您需要从每个控件中获取&记得使用这些自定义的

控件。


＃3更多的工作就是创建Provider本身（然后是单个派生的

控制），然而在多个

表格上使用提供商真的很容易。


我通常赞成＃2作为不变的我正在添加其他自定义到

控制......


＃2& ＃3是设计师友好！


希望这有帮助

Jay

Stefan,
As Chris suggests you can use the GotFocus & LostFocus events for this.

To minimize duplicate code I would consider using:
1. a single event handler for all controls
2. derived controls
3. an ExtenderProvider (implement System.Component.IExtenderProvider)

With #1 you need to add the same "handler" on each form, plus wire all the
controls to the handler.

With #2 you need to derive from every control & remember to use these custom
controls.

With #3 its more work to create the Provider itself (then a single derived
control), however it is then really easy to use the provider on multiple
forms.

I normally favor #2 as invariable I am adding other customizations to the
controls...

Both #2 & #3 are "designer friendly"!

Hope this helps
Jay
