如何在asp.net mvc

Question

我在单个视图中有2个表单，下面是代码。

 @model MCRP.Models.tblRequest
@{
  ViewBag.Title = "Review Request";
}
@using (Html.BeginForm("InsertForm", "Home"))
{
    @Html.EditorFor(model => model.ContactEmailAddress, new { htmlAttributes = new {id = "txtdelivery"} })
    <input type="submit" onclick="return validate();" value="submit" id="submitfilteration" class="btn btn-primary pull-left" />
}
@using (Html.BeginForm("Delete", "Home"))
{
     Are you sure you want to delete Property ?
    <input type="submit" value="Delete" class="btn btn-danger" />
}

但是点击删除按钮，插入txtdelivery的文本就会消失

控制器

public ActionResult ReviewRequest()
{         

        if (Session["AddtoCart"] != null)
        {
            DataTable dt = (DataTable)Session["AddtoCart"];
            if (dt.Rows.Count > 0)
            {
                ViewBag.addedtocart = (DataTable)Session["AddtoCart"];
            }
            else
            {
                ViewBag.addedtocart = null;
                ViewBag.EmptyCart = "Your Cart Is empty";
            }
        }
        else
        {
            ViewBag.addedtocart = null;
            ViewBag.EmptyCart = "Your Cart Is empty";
        }
        return View();

}
public ActionResult InsertForm(tblRequest Request)
