ASP CORE动态更新viewbag日期标题

Question

您好，我是ASP核心的新手，已受命进行日记应用程序。单击上周按钮时，表的日期标题发生了更改，我遇到了问题。按下按钮时，它应该显示上周和下周的日期。如果这是一个非常愚蠢的问题，或者我打算完全错误地这样做，请提前道歉。每当页面加载时，它都可用于获取当前星期几的日期，但在两周之间无法滑动。

如果需要更多信息，请告诉我。。谢谢:)

<input type="submit" method="index" value="Previous Week" class="btn btn-light" onclick="location.href = '@Url.Action("Index", "Appointment",new {mon = ViewBag.monday, tues = ViewBag.tuesday, wed = ViewBag.wednesday, thurs = ViewBag.Thursday, fri = ViewBag.friday, sat = ViewBag.saturday,sun = ViewBag.sunday})'"/>

            ViewBag.saturday = Sat.AddDays(-7);
            ViewBag.sunday = sun.AddDays(-7);
