拖动多个项目时，此视图不允许 DataGrid 'EditItem' [英] DataGrid 'EditItem' is not allowed for this view when dragging multiple items

问题描述

我有一个数据网格，它可以获取这样的数据:

I have a datagrid which gets data like this:

    public struct MyData
    {
        public string name { set; get; }
        public string artist { set; get; }
        public string location { set; get; }
    }

    DataGridTextColumn col1 = new DataGridTextColumn();
    col4.Binding = new Binding("name");
    dataGrid1.Columns.Add(col1);
    dataGrid1.Items.Add((new MyData() { name = "Song1", artist = "MyName", location =     "loc"}));
    dataGrid1.Items.Add((new MyData() { name = "Song2", artist = "MyName", location =     "loc2"}));

问题是——每当用户尝试编辑一个单元格或拖动多个单元格时——应用程序就会抛出异常:

The problem is- whenever a user tries to edit a cell or drags multiple cells- the app throws an exception:

System.InvalidOperationException 未处理
消息:此视图不允许使用EditItem".

System.InvalidOperationException was unhandled
Message: 'EditItem' is not allowed for this view.

这是为什么?是不是因为输入数据的方式?
有什么想法吗?
谢谢！

Why is this? Is it because of the way the data is entered?
Any ideas?
Thanks!

推荐答案

不要使用 struct，而是使用 class.

Instead of using a struct use a class instead.

更新的答案:尝试将您的 MyData 实例添加到列表中，然后将该列表分配给 DataGrid.ItemsSource

UPDATED ANSWER: Try adding your MyData instances to a List then assigning that list to the DataGrid.ItemsSource
