更改带有选项卡的接受按钮

问题描述

我有一个用 C# 编写的 Windows 窗体应用程序，它有三个选项卡，我想用活动选项卡更改接受按钮.就像当我在标签 1 中时，我希望按钮 _1 成为接受按钮，但是当我在标签 3 中时，我希望 button_3 成为我的接受按钮.我无法弄清楚如何做到这一点，也许我在搜索中没有使用正确的术语，但我在网上找不到任何好的资源来告诉我如何做到这一点.

I have a windows form application written in C# and it has three tabs and I would like the accept button change with the active tab. Like When I am in tab 1 I want button _1 to be the accept button but when I am in tab 3 I want button_3 to be my accept button. I cannot figure out how to do this and maybe I'm not using the correct terms in my searches but I cannot find any good resources online showing me how to do this.

推荐答案

最好的猜测是连接到 SelectedIndexChanged 选项卡控件上的事件并更改 AcceptButton 取决于选择的选项卡.伪代码:

Best guess would be to hook in to the SelectedIndexChanged event on the tab control and change the AcceptButton depending on which tab is selected. Pseudo-code:

Form_OnLoad(...)
{
    this.tabControl.SelectedIndexChanged += (s,e) => {
        TabControl tab = s as TabControl;
        switch (tab.SelectedIndex){
            case 3:
                this.AcceptButton = this.button_3;
                break;
            case 2:
                this.AcceptButton = this.button_2;
                break;
            case 1:
            default:
                this.AcceptButton = this.button_1;
                break;
        }
    };
}

或者类似的东西.
