Question

I have two action results in my Controller. Overview and About.

public ActionResult Overview(int id)
{
    return View(new OverviewModel() { Project = db.People.Find(id) });
}

public ActionResult About(int id)
{
    return View(new AboutModel() { Project = db.People.Find(id) });
}

I would like to remember the id that was passed in to Overview and use it on the About as the default. I don’t know how to keep this Id constant while the user switches tabs from Overview to About.

You can try storing the id in TempData. Maybe something like this (not tested)

public ActionResult Overview(int id)
{
    TempData["YourId"] = id;
    return View(new OverviewModel() { Project = db.People.Find(id) });
}

public ActionResult About(int? id)
{
    id = id ?? int.Parse(TempData["YourId"].ToString());
    return View(new AboutModel() { Project = db.People.Find(id) });
}
