如何截取TAB键preSS在C＃prevent标准焦点变化 [英] How to intercept the TAB key press to prevent standard focus change in C#

问题描述

通常，当pressing焦点更改到指定的Tab键顺序的下一个控件TAB键。我想prevent而拥有TAB键做别的事情。就我而言，我想从一个组合框更改焦点到一个完全不同的控制。我不能设置Tab顺序做到这一点。我需要以编程方式做到这一点。任何想法如何？这似乎是KeyDown和关键preSS事件不能正确处理TAB键。 谢谢你。

Normally when pressing the TAB key you change the focus to the next control in the given tab order. I would like to prevent that and have the TAB key do something else. In my case I'd like to change focus from a combobox to a completely different control. I can't do this by setting the tab order. I need to do this programatically. Any idea how? It seems like the KeyDown and KeyPress events can't handle TAB key correctly. Thanks.

推荐答案

覆盖 ProcessDialogKey 或 ProcessTabKey 窗体上和你要取决于其控制的重点是逻辑。

Override ProcessDialogKey or ProcessTabKey on your Form and do the logic you want depending on which control is focused.
