我想你会需要一些客户端code。

I think you will need some client side code.

尝试：

<div id="partialSummaryDiv"> Html.RenderPartial("~/Views/Account/Partials/LoginForm.cshtml", Model);</div>

事件你有你的Ajax调用

Event you'll have your ajax call

$.ajax({
url: "/Controller/Action",
type: "POST",
success: function (result) {
     // refreshes partial view
    $('#partialSummaryDiv').html(result);
}
});
