当按下十进制键时，跳至下一个文本框 [英] when decimal key is pressed tab to next textbox

问题描述

我正在尝试创建一个IP地址输入文本框，就像他们在Windows中创建的那样.

当用户按十进制键(.)时，应按Tab键并转到下一个
文本框.

我该如何使用Visual C#来做到这一点?

在此先感谢:)

推荐答案

处理按键按下事件.
每次.按下，通过代码跳至下一个.

可以使用SendKeys 方法完成.

Handle the key down event.
Every time a . is pressed, tab to the next through code.

This can be done using the SendKeys method.

1)已经完成，仅按TAB键，不按点即可.如果您导致用户碰到点，他们会讨厌的.这不是最佳选择.参见下文，以获得更好的结果.

2)IP地址太容易使用四个文本框播放.使用System.Windows.Forms.MaskedTextBox看起来像是专门设计来编辑IP地址的！

1) This is already done, only press TAB, not dot. If you cause the users to hit dot, they''ll hate it. This is not the best option. See below to a better one.

2) IP address is too easy to play with four text boxes. Use System.Windows.Forms.MaskedTextBox which looks like it was specially designed to edit IP addresses!
