MVC会话未在部分视图中显示

Question

我正在回复一个控制器并设置Sessions。设置后，它会显示在第一个选项卡中，但是当我单击下一个加载另一个部分视图的选项卡时，我看不到会话设置。

order.cshtml with Tabs ...

<div id="tabs">
    <ul class="nav nav-tabs">
        <li><a href="#tabs-1">General</a></li>
        <li><a href="#tabs-2">Item</a></li>
        <li><a href="#tabs-3">Total</a></li>       
    </ul>


    <div id="tabs-1">
        @{Html.RenderPartial("_Partial_General_Tab", Model.GeneralTab);}
    </div>

    <div id="tabs-2">
        @{Html.RenderPartial("_Partial_Item_Tab", Model.ItemTab);}
    </div>

    <div id="tabs-3">
        Content for Tab 3 goes here.<br />      
    </div>

</div>

[HttpPost]

public ActionResult Edit(ORDERMetadata model)
{            
    try
    {       

        // update order
        ....
        db.Entry(order).State = EntityState.Modified;
        db.SaveChanges();

        Session.Clear();
        Session["Order_Number"] = model.Order_Number;
        Session["PrincId"] = model.Princ_ID;
        Session["CustId"] = model.Cust_ID;

        return PartialView("_Partial_General_Tab", model);

    }
    catch (DbEntityValidationException ex)
    {
        return RedirectToAction("Index", "Error");

    }
