连续退格不适用于C#中的文本框 [英] Continuous Backspace is not working for textbox in c#

问题描述

我在c#( windows )中的退格有一个问题

我在文本框的keyup事件中编写了以下代码，即(文本框位于第5个面板上)

I have a one problem for backspaces in c#(windows)

I have written following code in keyup event for textbox i.e (Text Box is placed On 5 th panel)

if(e.keydata==keys.back)

   {
   sendkeys.send=("+{BS}");
   Sendkeys.send={Break};
   }

它将仅删除一个字符.当我按下退格按钮，但是当我按住退格按钮时，它不会删除完整的字符.只需按一下就可以删除一个字符.您能给我解决方法吗?

推荐答案

您认为何时获得KeyUp事件?

我会给你一个提示:

按下一个键-您会收到一个KeyDown事件.

按住它-您会收到KeyDown(有时是KeyPress)事件

放开钥匙-您会得到什么活动?

您要做的是改为处理Key Down或KeyPress事件...

When do you think you get the KeyUp event?

I''ll give you a clue:

Push a key down - you get a KeyDown event.

Hold it down - you get KeyDown (and sometimes KeyPress) events

Let go of a key - what event do you get?

What you want to do is handle the Key Down or KeyPress event instead...
