如何基于ASP.Net Core中的某些值显示/隐藏列？

Question

所以我有以下模型类：

Start

将以如下方式可视化：

我想隐藏并显示Stop，Finish和Finished按钮，具体取决于某些值。例如：

如果true是InProgress，则所有按钮都将被隐藏。

如果true是Stop，则Finish和Aborted按钮将可见，而另一个按钮将被隐藏。

如果true是Start，则Stop将可见，而Finish和 <td><a class="btn btn-sm btn-primary" asp-action="InProgress" asp-route-id="@p.Id">Start</a></td> <td><a class="btn btn-sm btn-primary" asp-action="Abort" asp-route-id="@p.Id">Stop</a></td> <td><a class="btn btn-sm btn-primary" asp-action="Finish" asp-route-id="@p.Id">Finish</a></td> 将被隐藏。

关于UI部分，我是一个初学者，所以我找不到解决方法。下面是包含我所讨论的按钮的3列代码。

我应该怎么做才能做到这一点？

Answer 1

您可以添加if语句：

@if (p.InProgress == true)
{
 <td><a class="btn btn-sm btn-primary" asp-action="InProgress" asp-route- 
 id="@p.Id">Start</a></td>             
}
