“结束编辑”事件在文本框中 [英] Event for "end edit" in a text box

问题描述

我在winform（c＃）中使用文本框，并使用的文本在数据库中进行查询。

I am using a textbox in winform (c#) and using the text of to make consults in a database.

但是我需要不断地查询文本框的文本每次文本更改时。因此，对于这些我使用KeyUp。但是这个事件太慢​​了。

But i need constantly consult the text of the textbox every time that text change. So for these i use the KeyUp. But this event is too slow.

是否有任何事件在文本框编辑完成后才触发？我考虑了完成2个条件

Is any event that just fire when the textbox editing has been finished ?. I consider for finish 2 conditions

控件失去了焦点。
控件有200毫秒没有按键操作

The control lost focus. The control has 200ms without keypress

推荐答案

Otherwise, you'll need to choose from one of the existing events. (Listed here)

想起来，您可能必须捕获多个事件。如果有人复制/粘贴，则拖动DragDrop，例如...

Come to think of it, you will likely have to capture multiple events. DragDrop if someone copies/pastes, for example...
