Question

问题是，当我填充数据网格时，它会向我显示数据库中可用的行数，但行中的数据在数据网格中是空的。这是一个片段：

private void button1_Click(object sender, RoutedEventArgs e)
        {
            try
            {                
                connection.Open();
                SqlCommand command = new SqlCommand();
                command.CommandText = "select item_name from prod_info";
                cmdd.Connection = connection;
                Datatable table= new Datatable();
                SqlDataAdapter adapter = new SqlDataAdapter(command);
                adapter.Fill(table);
                dataGrid1.ItemsSource = table.DefaultView;
                connection.Close();
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }

这是xaml代码：

<DataGrid AutoGenerateColumns="False" Height="308" HorizontalAlignment="Left" Margin="59,89,0,0" Name="dataGrid1" VerticalAlignment="Top" Width="502" ItemsSource="{Binding }"/>

Answer 1

首先：AutoGenerateColumns =＆＃34; True＆＃34;

那么也许它也是必要的：

dataGrid1.ItemsSource = table.AsDataView();
