Question

我在使用以下工作时遇到了一些麻烦：

我正在创建一个像这样的ObservableCollection：

ObservableCollection<OverViewItems> ocOrderData = new ObservableCollection<OverViewItems>();

OrderViewItems类如下所示：

    public class OverViewItems
    {
        public string OrderNo;
        public int Pieces;
        public string SenderName;
        public string ReceiverName;
        public string ReceiverAddress;
        public string ReceiverZip;
        public string ReceiverCity;
        public DateTime DelDate;
    }

然后我用一些样本数据填充它（在这种情况下是两行），如下所示：

            ocOrderData.Add(new OverViewItems
            {
                OrderNo = "TEST",
                Pieces = 1,
                SenderName = "TEST SENDER",
                ReceiverName = "TEST RECEIVER",
                ReceiverAddress = "TEST ADDRESS",
                ReceiverZip = "TEST ZIP",
                ReceiverCity = "TEST CITY",
                DelDate = DateTime.Now,
            });

            ocOrderData.Add(new OverViewItems
            {
                OrderNo = "TEST 2",
                Pieces = 1,
                SenderName = "TEST SENDER 2",
                ReceiverName = "TEST RECEIVER 2",
                ReceiverAddress = "TEST ADDRESS 2",
                ReceiverZip = "TEST ZIP 2",
                ReceiverCity = "TEST CITY 2",
                DelDate = DateTime.Now,
            });

并尝试将其绑定到WPF Datagrid，如下所示：

dataGrid1.ItemsSource = ocOrderData;

Datagrid的XAML如下所示：

        <DataGrid 
        AutoGenerateColumns="True" 
        Height="200" 
        HorizontalAlignment="Left" 
        Margin="23,172,0,0" 
        Name="dataGrid1" 
        VerticalAlignment="Top" 
        Width="1084" 
        />

现在，datagrid显示两行ok，但是没有数据，没有列，除了包含两行的空数据网格之外没有任何内容。为什么是这样？我做错了什么？

感谢任何帮助。：）

Answer 1

您必须使用OverViewItems类中的属性而不是简单的公共字段这样做应该使DataGrid正确地创建列。

public class OverViewItems
{
    public string OrderNo { get; set; }
    public int Pieces { get; set; }
    public string SenderName { get; set; }
    public string ReceiverName { get; set; }
    public string ReceiverAddress { get; set; }
    public string ReceiverZip { get; set; }
    public string ReceiverCity { get; set; }
    public DateTime DelDate { get; set; }
}

Answer 2

你可以绑定到公共属性而不是字段。

public class OverViewItems
{
    public string OrderNo {get;set};
    public int Pieces {get;set};
    public string SenderName {get;set};
    public string ReceiverName {get;set};
    public string ReceiverAddress {get;set};
    public string ReceiverZip {get;set};
    public string ReceiverCity {get;set};
    public DateTime DelDate {get;set};
}

将Datagrid绑定到observablecollection不会仅显示数据行
