WPF绑定路径= /不工作？ [英] WPF Binding Path=/ not working?

问题描述

我已经设置了我的的DataContext 是这样的：

I've set up my DataContext like this:

<Window.DataContext>
    <c:DownloadManager />
</Window.DataContext>

其中，下载管理器是可枚举＆LT; D​​ownloadItem＆GT; 。然后，我把我的的DataGrid 是这样的：

Where DownloadManager is Enumerable<DownloadItem>. Then I set my DataGrid like this:

<DataGrid Name="dataGrid1" ItemsSource="{Binding Path=/}" ...

所以，它应该列出所有DownloadItems，对不对？所以，我应该能够把我列这样的：

So that it should list all the DownloadItems, right? So I should be able to set my columns like:

<DataGridTextColumn Binding="{Binding Path=Uri, Mode=OneWay}"

其中，乌里是属性的 DownloadItem 。但它似乎并不喜欢这样。在可视化的属性编辑器，它不承认乌里是一个有效的属性，所以我猜，我做错了什么。

Where Uri is a property of the DownloadItem. But it doesn't seem to like this. In the visual property editor, it doesn't recognize Uri is a valid property, so I'm guessing I'm doing something wrong.

这是工作前，当我有数据网格绑定到值，但后来我把那个枚举出的下载管理器键，使自己枚举。我该如何解决这个问题？

It was working before, when I had the data grid binding to Values, but then I took that enumerable out of the DownloadManager and made itself enumerable. How do I fix this?

PS：所谓不工作我的意思是没有列出任何项目。我已经添加了一些对DM的构造，所以它不应该是空的。

PS: By "doesn't work" I mean it doesn't list any items. I've added some to the constructor of the DM, so it shouldn't be empty.

推荐答案

尝试的ItemsSource ={结合}。它应该是足够的。

Try ItemsSource="{Binding}". It should be enough.
