將SQL查詢結果傳遞到多個文本框中

我有一個由SQL服務器填充的數據網格。我試圖從條目列表中選擇一行並將它們輸入到網格外的文本框中。我似乎無法找到一種方法將查詢結果轉換爲可管理的數據，而不是填充網格。將SQL查詢結果傳遞到多個文本框中

C＃

MoviesEntities dataEntities = new MoviesEntities(); 
ObjectQuery<MovieTable> _movies = dataEntities.MovieTables; 

var query = 
    from MovieTable in _movies 
    where MovieTable.Title == MMEM.MovieTitle 
    select MovieTable.id; 
    string result = Convert.ToString(query); //or something??

XAML：

<Window x:Class="MovieApp.MainWindow" 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    Title="MainWindow" 
    Height="650" 
    Width="525" 
    ResizeMode="NoResize" 
    WindowStartupLocation="CenterScreen" 
    xmlns:vm="clr-namespace:MovieApp"> 
<Window.Resources> 
    <vm:MovieAppViewModel x:Key="MovieAppViewModel"/> 
</Window.Resources> 
<StackPanel x:Name="RootStackPanel" DataContext="{StaticResource MovieAppViewModel}"> 
    <Grid HorizontalAlignment="Center" Height="99" Width="440"> 
     <Grid.ColumnDefinitions> 
      <ColumnDefinition Width="Auto"/> 
      <ColumnDefinition Width="Auto"/> 
      <ColumnDefinition Width="Auto"/> 
      <ColumnDefinition Width="Auto"/> 
     </Grid.ColumnDefinitions> 
     <Grid.RowDefinitions> 
      <RowDefinition Height="Auto"/> 
      <RowDefinition Height="Auto"/> 
      <RowDefinition Height="Auto"/> 
     </Grid.RowDefinitions> 
     <TextBlock Grid.Column="0" Text="Movie Title" Margin="30 0 30 0" HorizontalAlignment="Center" FontWeight="Heavy"/> 
     <TextBlock Grid.Column="1" Text="Rating" Margin="30 0 30 0" HorizontalAlignment="Center" FontWeight="Heavy"/> 
     <TextBlock Grid.Column="2" Text="Stars" Margin="30 0 30 0" HorizontalAlignment="Center" FontWeight="Heavy"/> 
     <TextBlock Grid.Column="3" Text="Release Year" Margin="30 0 30 0" HorizontalAlignment="Center" FontWeight="Heavy"/> 
     <TextBox Grid.Column="0" TextAlignment="Center" Text="{Binding MMEM.MovieTitle}" IsEnabled="{Binding MMEM.IsEditable}" Grid.Row="1" MaxLength="50" Width="100"/> 
     <TextBox Grid.Column="1" TextAlignment="Center" Text="{Binding MMEM.Rating}" IsEnabled="{Binding MMEM.IsEditable}" Grid.Row="1" MaxLength="5" Width="55"/> 
     <TextBox Grid.Column="2" TextAlignment="Center" Text="{Binding MMEM.Stars}" IsEnabled="{Binding MMEM.IsEditable}" Grid.Row="1" MaxLength="5" Width="20"/> 
     <TextBox Grid.Column="3" TextAlignment="Center" Text="{Binding MMEM.ReleaseYear}" IsEnabled="{Binding MMEM.IsEditable}" Grid.Row="1" MaxLength="20" Width="100"/> 
    </Grid> 
    <Button Content="Edit Mode" Command="{Binding ToggleCommand}"/> 
    <DataGrid 
     Width="Auto" 
     SelectionMode="Extended" 
     IsReadOnly="True" 
     AutoGenerateColumns="False" 
     ItemsSource="{Binding MMLM.MoviesList}" 
     DataContext="{StaticResource MovieAppViewModel}"> 
     <DataGrid.Columns> 
      <DataGridTextColumn Width="200" Header="Title" Binding="{Binding Title}"/> 
      <DataGridTextColumn Width="100" Header="Rating" Binding="{Binding Rating}"/> 
      <DataGridTextColumn Width="100" Header="Stars" Binding="{Binding Stars}"/> 
      <DataGridTextColumn Width="93" Header="Release Year" Binding="{Binding ReleaseYear}"/> 
     </DataGrid.Columns> 
    </DataGrid> 
</StackPanel>

我假設有比解析行成字符串和填充的文本框更有效的方式下，但在這一點我會拿我能得到的！

感謝您的任何輸入！

安置自己的XAML - 無論是電網和文本框代碼。你應該能夠將你的網格綁定到數據源並讓它自動填充（半）。 – ChrisF 2012-02-24 21:18:22

網格自動填充，但我想從選定的行中獲取數據到上面的文本框中。不知道這是你的意思，但是我已經有了這部分。感謝您的輸入 – Josh 2012-02-24 21:22:03

您應該能夠從網格中獲取選定的行（我使用Silverlight，因此我無法加速WPF的確切語法），它將爲您提供一個對象 - MovieEntity？在這種情況下。 – ChrisF 2012-02-24 21:24:15

僅舉thedatagrid如masterDG

那麼在細節

Binding ElementName=masterDG, path=SelecedItem.Title
