绑定一个ObservableCollection到ListView [英] Bind an ObservableCollection to a ListView

问题描述

我有麻烦让我的数据，以正确绑定的巨大数额。我从人的类似问题在这里阅读上的大部分职位，但由于某种原因，我不能得到它的点击。

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.

我的表中的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>

在我的code我有：

Within my code I have:

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; }

}

在试图更新我使用表

_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()
});

新项目似乎越来越正确添加，但没有更新的列表视图。

New items seem to be getting added correctly, but nothing is updated on the listView.

我已经经历教程是这样写着：的http://www.switchonthe$c$c.com/tutorials/wpf-tutorial-using-the-listview-part-1

I have read through tutorials like this: http://www.switchonthecode.com/tutorials/wpf-tutorial-using-the-listview-part-1

我试图将所有的通知code，它建议在其他职位。没有什么工作对我来说。

And I have tried adding all of the notification code that is suggested in other posts. Nothing is working for me.

和想法将AP preciated。

And ideas would be appreciated.

推荐答案

而不是的DataContext ={结合DocumentList}尝试的ItemsSource = {结合DocumentList}。
