Question

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.

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;
        }
    };
}

Or something of the sort.
