按钮位于 tabitem 下(在 tabcontrol 内),但处理程序需要位于主 window

Button located under tabitem (within tabcontrol) but the handler needs to be in the main window

我有一个主 windows,其中包含一些控件,包括一个选项卡控件。选项卡控件本身有多个 tabitem。每个选项卡项目都有独特的设计。当用户单击其中一个选项卡项中的按钮时,我希望事件处理程序位于主 window 的 .cs 文件中。我想不出一个办法,谁能启发我?

我的语法可能不完美,但是这个呢:

public interface ITabControlWithNotifications
{
    void OnButtonClicked(...);
}

public sealed class TabControlWithNotifications : TabControl, ITabControlWithNotifications
{
    public void OnButtonClicked(...)
    {
        ...
    }
}

public sealed class TabPageWithNotifications : TabPage
{
    private readonly ITabControlWithNotifications parentTabControl;

    public TabPageWithNotifications(ITabControlWithNotifications tabControlWithNotifications)
    {
        this.parentTabControl = tabControlWithNotifications;
        this.InitialzeComponents();
    }

    ... ClickEventHandler(...)
    {
        this.parentTabControl.OnButtonClicked(...);
    }
}

public sealed class TabControlFactory
{
    public void Build()
    {
        var parentTabControl = new TabControlWithNotifications();
        var tabPage1 = new TabPageWithNotifications(parentTabControl);
        var tabPage2 = new TabPageWithNotifications(parentTabControl);
        var tabPage3 = new TabPageWithNotifications(parentTabControl);
        parentTabControl.Controls.Add(tabPage1);
        parentTabControl.Controls.Add(tabPage2);
        parentTabControl.Controls.Add(tabPage3);
    }
}
