datagrid wpf中没有显示任何内容

Question

您好 我正在使用datagrid视图。数据被添加到表格中，从监视窗口中，我可以看到表格中包含1行但数据网格中没有显示任何内容。

以下是代码：

 DataTable PopulateDataGrids(DataGrid grid, List<ReterivedEmailData> data)
        {
            DataTable table = new DataTable();
            table.Columns.Add("Sr No");
            table.Columns.Add("Company Name");
            table.Columns.Add("Email");

            int count = 0;

            DataRow row;

            foreach (ReterivedEmailData item in data)
            {
                count++;
                row = table.NewRow();
                row["Sr No"] = count.ToString();
                row["Company Name"] = item.Name;
                row["Email"] = item.Email;
                table.Rows.Add(row);
            }
            return table;
        }

这是方法调用：

dataGridBoatCompanyList.DataContext = PopulateDataGrids(dataGridBoatCompanyList, boat);

XAML标记：

<DataGrid AutoGenerateColumns="True" Height="322" HorizontalAlignment="Left" Margin="6,6,0,0" Name="dataGridBoatCompanyList" VerticalAlignment="Top" Width="500" />

Answer 1

尝试将ItemsSource="{Binding}"添加到您的网格

<DataGrid DataContext="{Binding}" AutoGenerateColumns="True" Height="322" HorizontalAlignment="Left" Margin="6,6,0,0" Name="dataGridBoatCompanyList" VerticalAlignment="Top" Width="500" />

另外，您在方法PopulateDataGrids()中没有使用第一个参数。如果您要做的就是填充网格，那么您可以跳过该方法并使用

dataGridBoadCompanyList.ItemsSource=  new ObservableCollection<ReterivedEmailData>(boat); 

编辑：

如果我试试这个

void MainWindow_Loaded(object sender, RoutedEventArgs e)
        {
            dataGridBoatCompanyList.ItemsSource =
                new ObservableCollection<ReterivedEmailData>(new[]
                                                                 {
                                                                     new ReterivedEmailData
                                                                         {Email = "dfsd", Name = "fadsfds"}
                                                                 });
        }

并且

<DataGrid ItemsSource="{Binding}" AutoGenerateColumns="True" Height="322" HorizontalAlignment="Left" Margin="6,6,0,0" Name="dataGridBoatCompanyList" VerticalAlignment="Top" Width="500" />

我得到一个像这样的填充列表

很难说没有看到你的DataGrid的XAML定义，但也许你的意思是

dataGridBoatCompanyList.ItemsSource = PopulateDataGrids(dataGridBoatCompanyList, boat);
