如何集中控制KeyPress事件 [英] How to focus control for KeyPress event

问题描述

我正在开发计算器程序。如何将TextBox重点放在KeyPress事件上。所以它准备好从键盘输入。我的程序需要点击该文本框然后从键盘输入。

我希望文本框能够自动聚焦在按键事件上。不需要在该文本框上手动单击以便我从键盘输入。

这是Windows窗体应用程序。



textbox1.focus（）;



无效。

解决方案

< blockquote>如果它是一个Web应用程序你的文本框id点焦点在jquerry。

请提及使用你的工作。

首先查看TabOrder您的表格：

https：// msdn。 microsoft.com/en-us/library/aa984423(v=vs.71).aspx [ ^ ]

或

http://webcheatsheet.com/HTML/controll_tab_order。 php [ ^ ]

当表单/页面加载时，最低的Tab键顺序控件获得焦点。



如果你需要设置一个特定的控件以编程方式获得焦点，那么你可以做适用于Winforms的焦点方法 [ ^ ]

尝试...

Kindly Mention using Which your working .

Start by looking at the TabOrder for your form:
https://msdn.microsoft.com/en-us/library/aa984423(v=vs.71).aspx[^]
Or
http://webcheatsheet.com/HTML/controll_tab_order.php[^]
The lowest tab order control gets the focus when the form / page loads.

If you need to set a specific control to get the focus programmatically, then you can do it for Winforms with the Focus method[^]

Try ...

TextBox1.Select
