Question

我需要一些建议。我想创建Wrapping ListView，其中所选项目的详细信息已在其他项目之间内联查看。

一张图片胜过千言万语。没有任何选定的项目： any selected items 使用所选项目： selected item 我正在努力实现与Google Image类似的效果。我试过不同的方法来实现这一目标。也许改变DataTemplate Change WPF DataTemplate，但仍然不是我想要的。

我很乐意接受任何建议。非常感谢。

到目前为止，我只有这段代码：

RestResult<Agent> agentResults;
RestResult<Company> companyResults;
RestResult<Contact> contactResults;
RestResult<Ticket> ticketResults;

Parallel.Invoke(
    () => agentResults = agentService.GetAll(),
    () => companyResults = companyService.GetAll(),
    () => contactResults = contactService.GetAll(),
    () => ticketResults = ticketService.GetAll()
);

更新

您好，一段时间后我回到了这个问题，但我需要一些建议。我想我正走在正确的轨道上。我用ItemDetailTemplatem创建了自己的ListView控件。一切都运作良好，除了ItemDetail。我需要ItemDetail跨越宽度ListView。看图：以下是源代码：ListViewWrapPanelExpand.zip 我会很高兴任何建议。非常感谢
