Windows窗体事件“选择选项卡”？

本文介绍了Windows窗体事件“选择选项卡”？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我正在C＃中构建一个 Windows Forms 应用程序。选择选项卡菜单上的某个选项卡时，如何触发代码？

解决方案

我认为这是 TabControl.SelectedIndexChanged 事件。

只要看看MSDN。我从那里拿走了假设你命名你的tab控件 tabControl1 。 您需要使用以下方式订阅此事件：

tabContrl1.TabControl.SelectedIndexChanged + = tabControl1_SelectedIndexChanged;

添加事件处理程序

private void tabControl1_SelectedIndexChanged（Object sender，EventArgs e）{ MessageBox.Show（你在TabControl.SelectedIndexChanged事件中）; }

I'm building a Windows Forms application in C#. How do I trigger code when a certain tab on a tab menu is selected?

解决方案

I think it is the TabControl.SelectedIndexChanged event.

Just look at MSDN. I took it from there. Suppose you named your tab control tabControl1. You need to subscribe to this event using:

tabContrl1.TabControl.SelectedIndexChanged += tabControl1_SelectedIndexChanged;

And add the event handler

private void tabControl1_SelectedIndexChanged(Object sender, EventArgs e) { MessageBox.Show("You are in the TabControl.SelectedIndexChanged event."); }
