    You can do different things based on the tab that is currently selected by using the following code in the AcceptButton_Click event handler:

    if (tabControl1.SelectedTab == tabPage1)
    {
        //Do something
    }
    else if (tabControl1.SelectedTab == tabPage2)
    {
        //Do something different
    }
    

    If you prefer to work with strings, each tab page has a unique name:

    switch (tabControl1.SelectedTab.Name)
    {
        case "Tab1Name":
            //Do something
            break;
        case "Tab2Name":
            //Do something different
            break;
    }

    TabControl have SelectedIndexChanged event.

    private void tabControl1_SelectedIndexChanged(object sender, EventArgs e)
        {
            if (tabControl1.SelectedTab == tabControl1.TabPages["RenewalTab"])
            {
                this.AcceptButton = btnRenewal;
            }
            else if (tabControl1.SelectedTab == tabControl1.TabPages["SellerTab"])
            {
                this.AcceptButton = btnSeller;
            }
        }

    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.
