我想在索引页中删除表行，并且在删除行之前，我必须在数据库中进行修改并显示弹出窗口以确认删除操作。但是，当我删除该行时，它已在数据库中删除，但是在Ajax中执行成功操作后，我的页面没有刷新。下面是我为视图和控制器编写的代码，并给出了模型定义作为参考。
// Controller

}

{
db.Dispose();
}

foreach(var d in db.acquisition_lease_case_record_master.Where(c => c.int_deleted_sts == 0).Include(c => c.vill_code).ToList())
{
d.chrv_land_class_cd = db.landclasslistmaster.Where(c => c.chrv_landclass_cd == d.chrv_land_class_cd).Select(c => c.chrv_landclass).SingleOrDefault();
listdata.Add(d);
}
return View("Index",listdata);
}
