如何在转发器中执行if语句 [英] How can i do an if statement inside a repeater

问题描述

< asp：Repeater> 让我发疯...

我需要做

<ItemTemplate>
    <% if (Container.DataItem("property") == "test") {%>
        I show this HTML
    <% } else { %>
        I show this other HTML
    <% } %>
</ItemTemplate>

但我不能为我的生活找到任何方法来实现这一目标。三元不是很好，因为HTML的数量非常大，通过DataBind事件设置标签也不是很好，因为我必须在代码隐藏中拥有大块的HTML。

But I can't for the life of me find any way to make that happen. Ternary isnt any good, because the amount of HTML is quite large, setting labels via a DataBind event is not very good either, as I'd have to have large blocks of HTML in the code-behind.

肯定有办法做到这一点....

Surely there's a way to do this....

推荐答案

你可以尝试创建一种在ViewModel类中，对代码隐藏做出决定，然后对转发器感到满意，只需显示正在给出的数据。

You could try creating a kind of ViewModel class, do the decision on your code-behind, and then be happy with your repeater, simply displaying the data that it is being given.

这是一种方式将逻辑与UI分开。然后，你可以拥有一个简单显示数据的哑巴UI，而无需决定显示什么/如何显示。

This is a way to separate logic from UI. You can then have a dumb-UI that simply displays data, without having to decide on what/how to show.
