C＃标签的TabControl的切换 [英] C# Tab switching in TabControl

问题描述

荫面临这样的问题，我觉得这很难克服。在的WinForms我有n个TabPage一个TabControl。我想延长Ctrl + Tab键/按Ctrl + Shift + Tab键切换。所以我写了一些代码，只要罚款的重点是TabControl的或表上工作。当应用程序的重点是INSIDE的TabPage（例如其上放置TabPage的内部按钮），同时按下Ctrl + Tab键，我的代码将被忽略，TabControl的跳到他自己的TabPage（避免我的代码）。

Iam facing such problem, which I find hard to overcome. In WinForms I got a TabControl with n TabPages. I want to extend the Ctrl+Tab / Ctrl+Shift+Tab switching. so I wrote some code which works fine as long as the focus is on TabControl or on the Form. When application focus is INSIDE of TabPage (for example on a button which is placed inside of TabPage), while pressing Ctrl+Tab, my code is ignored and TabControl skips to TabPage on his own (avoiding my code).

任何想法？

推荐答案

您需要从TabControl的派生和覆盖ProcessCmdKey，虚方法以覆盖Ctrl-Tab组合的行为。

You need to derive from TabControl and override ProcessCmdKey, virtual method in order to override the Ctrl-Tab behavior.

例如：

public class ExtendedTabControl: TabControl
{
    protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
    {
        if (keyData == (Keys.Control | Keys.Tab))
        {
            // Write custom logic here
            return true;
        }
        if (keyData == (Keys.Control | Keys.Shift | Keys.Tab))
        {
            // Write custom logic here, for backward switching
            return true;
        }
        return base.ProcessCmdKey(ref msg, keyData);
    }
}
