在浏览器上运行网页后，我的复选框没有显示。 在添加新代理的布局之前，当页面是空白的，只有复选框时，它们才显示出来。 我尝试在不同的浏览器上运行它，但仍然没有这样做。 我不知道是否需要控制器和模型，但这是cshtml代码：
@model AgentsManagements.ActivityModel
@section ViewHead{
<link href="~/Content/Agents/CSS/Shared.css" rel="stylesheet" />
<link href="~/Content/Shared/CSS/FrameWork/sweetalert.css" rel="stylesheet" />
}
