WPF DataGrid - 新条目的行不可见 [英] WPF DataGrid - row for new entry not visible

问题描述

问题是DataGrid中的空白行没有出现，ergo用户无法添加数据。
这里是代码：

The problem is, that the blank row in the DataGrid isn't appearing, ergo user can not add data. Here is the code:

System.Collections.ObjectModel.ObservableCollection<CoreVocabularyEntry> dataList = new System.Collections.ObjectModel.ObservableCollection<CoreVocabularyEntry>();
    public VocabularyToolWindow()
    {
        InitializeComponent();
        dataList.Add(new CoreVocabularyEntry { Foreign = "ja", Native = "ano" });
        ListCollectionView view = new ListCollectionView(dataList);
        WordsDataGrid.ItemsSource = dataList;
        WordsDataGrid.CanUserAddRows = true;
        MessageBox.Show(view.CanAddNew.ToString());
    }

我不知道为什么view.CanAddNew等于false。这看起来像一个漂亮的标准场景，所以我可能有一些消失的东西。有人可以告诉我代码有什么问题吗？ CoreVocabularyEntry只是以下内容：

I can't figure out why view.CanAddNew equals false. This looks like a pretty standart scenario, so there's probably something obvions I'm missing. Can someone tell me what is wrong with the code ? CoreVocabularyEntry is just the following:

public struct CoreVocabularyEntry : IVocabularyEntry
{
    #region IVocabularyEntry Members

    public string Foreign
    {
        get;
        set;
    }

    public string Native
    {
        get;
        set;
    }

    #endregion
}

Thx ，JK

推荐答案

移动 WordsDataGrid.CanUserAddRows = true; 您设置DataGrid的ItemSource。

Move WordsDataGrid.CanUserAddRows = true; above the statement where you set the DataGrid's ItemSource.

编辑：

只是注意到你没有不实施 IEditableObject 。您需要这样做才能使用DataGrid的编辑功能。

Just noticed you didn't implement IEditableObject. You'll need to do that for using the editing features of the DataGrid.
