Bind an ObservableCollection to a ListView
提问by Nathan Tornquist
I am having an immense amount of trouble getting my data to bind correctly. I have read most the posts on here from people with similar issues, but for some reason I just can't get it to click.
我在让我的数据正确绑定时遇到了很多麻烦。我已经阅读了来自有类似问题的人的大部分帖子，但由于某种原因，我无法点击它。
The XML for my table is:
我的表的 XML 是：
<Window ... DataContext="{Binding RelativeSource={RelativeSource Self}}" >
...
<ListView Height="124" HorizontalAlignment="Left" Margin="12,46,0,0" Name="listViewDocuments" VerticalAlignment="Top" Width="Auto" DataContext="{Binding DocumentList}">
<ListView.View>
<GridView>
<GridViewColumn Width="160" Header="Description" DisplayMemberBinding="{Binding Description}"/>
<GridViewColumn Width="160" Header="Date Filed" DisplayMemberBinding="{Binding DateFiled}"/>
<GridViewColumn Width="160" Header="Filed By" DisplayMemberBinding="{Binding UserFiledName}"/>
<GridViewColumn Width="150" Header="Page" DisplayMemberBinding="{Binding Pages}"/>
<GridViewColumn Width="150" Header="Notes" DisplayMemberBinding="{Binding Notes}"/>
<GridViewColumn Width="Auto" Header="" />
</GridView>
</ListView.View>
</ListView>
Within my code I have:
在我的代码中，我有：
public ObservableCollection<Document> _DocumentList = new ObservableCollection<Document>();
...
public ObservableCollection<Document> DocumentList{ get { return _DocumentList; } }
...
public class Document
{
public string Description { get; set; }
public string DateFiled { get; set; }
public string UserFiledName { get; set; }
public string Pages { get; set; }
public string Notes { get; set; }
public string Tag { get; set; }
}
In an attempt to update the table I use:
为了更新我使用的表：
_DocumentList.Add(new Document
{
Description = dr["Description"].ToString(),
DateFiled = dr.GetDateTime(dr.GetOrdinal("DateFiled")).ToShortDateString(),
UserFiledName = dr["UserFiledName"].ToString(),
Pages = dr.GetInt32(dr.GetOrdinal("Pages")).ToString(),
Notes = dr["Notes"].ToString(),
Tag = dr["FileID"].ToString()
});
New items seem to be getting added correctly, but nothing is updated on the listView.
新项目似乎被正确添加，但 listView 上没有任何更新。
I have read through tutorials like this: http://www.switchonthecode.com/tutorials/wpf-tutorial-using-the-listview-part-1
我已经阅读了这样的教程：http: //www.switchonthecode.com/tutorials/wpf-tutorial-using-the-listview-part-1
And I have tried adding all of the notification code that is suggested in other posts. Nothing is working for me.
我已经尝试添加其他帖子中建议的所有通知代码。没有什么对我有用。
And ideas would be appreciated.
和想法将不胜感激。

Instead of DataContext="{Binding DocumentList}"try ItemsSource="{Binding DocumentList}".
而不是DataContext="{Binding DocumentList}"尝试ItemsSource="{Binding DocumentList}"。
