Silverlight : DataGrid RowDetailTemplate에서 컨트롤에 액세스하는 방법

Question

아래 코드를 가지고 RowDetailsTemplate에서 "btnUpdate"단추 컨트롤을 가져 와서 코드의 가시성을 설정하고 싶습니다. 어떻게해야합니까? 어떤 조언도 감사 드리며 미리 감사드립니다.

<Grid x:Name="LayoutRoot" Background="White"> 
    <Grid HorizontalAlignment="Left" Name="grid1" VerticalAlignment="Top" > 
     <Grid.RowDefinitions> 
      <RowDefinition Height="40" /> 
      <RowDefinition Height="*" /> 
     </Grid.RowDefinitions> 
     <Grid.ColumnDefinitions> 

     </Grid.ColumnDefinitions> 
     <Grid HorizontalAlignment="Left" Name="grid2" VerticalAlignment="Top" Grid.RowSpan="2"> 
      <Grid.ColumnDefinitions> 
       <ColumnDefinition Width="500" /> 
       <ColumnDefinition Width="80*" /> 
       <ColumnDefinition Width="111*" /> 
       <ColumnDefinition Width="*" /> 
      </Grid.ColumnDefinitions> 
      <Button Content="Refresh" Click="btnRefresh_Click" Grid.Column="1" Height="23" HorizontalAlignment="Right" Name="btnRefresh" VerticalAlignment="Top" Width="80"/> 
      <Button Content="Add" Click="btnAdd_Click" Grid.Column="2" Height="23" HorizontalAlignment="Right" Name="btnInsert" VerticalAlignment="Top" Width="80" /> 
      <sdk:Label Height="28" HorizontalAlignment="Left" Name="Title" VerticalAlignment="Top" Content="Title" HorizontalContentAlignment="Left" FontSize="20" FontWeight="Bold" Width="Auto"/> 
     </Grid> 
     <data:DataGrid x:Name="OverviewDataGrid" Grid.Row="1" AutoGenerateColumns="False" RowEditEnded="OverviewDataGrid_RowEditEnded" SelectionChanged="OverviewDataGrid_SelectionChanged">

         </DataTemplate> 
        </data:DataGridTemplateColumn.CellTemplate>

</Grid> 

Answer 1

아래 단계에 따라 RowDetailsTemplate에서 컨트롤을 가져옵니다.

1. XAML에서 데이터 그리드에 loadingRowDetails 이벤트 {LoadingRowDetails="yourDataGrid_LoadingRowDetails"}를 추가합니다.

2. XAML 클래스

   private void yourDataGrid_LoadingRowDetails(object sender, DataGridRowDetailsEventArgs e) 
   {   
       Button btn = (e.DetailsElement as FrameworkElement).FindName("btnUpdate") as Button; 
       if (ok.Equals(false)) 
        btn.Visibility = System.Windows.Visibility.Collapsed; 
   }
