更改接受标签按钮

问题描述

我在C＃编写Windows窗体应用程序，它有三个标签，我想与有源标签接受按钮变化。就像当我在标签1我想按钮_1要接受按钮，但是当我在标签3我想button_3是我接受按钮。我无法弄清楚如何做到这一点，也许我不会在我的搜索使用正确的术语，但我不能在网上找到任何好的资源，向我展示如何做到这一点。

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

最好的猜测是在勾到 的SelectedIndexChanged 选项卡控件的事件，改变的取决于所选择的标签。伪code：

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;
        }
    };
}

或者是诸如此类的东西。

Or something of the sort.
