DataGridDetailsPresenter를 클릭하여 ParentDataGrid에서 DataGridRow를 선택하지 않으려면 어떻게해야합니까?

Question

DataGridDetailsPresenter가있는 DataGrid (ParentDataGrid)가 있습니다. DataGridDetailsPresenter에는 다른 DataGrid (ChildDataGrid)가 있습니다. ChildDataGrid에서 Row를 선택하면 ParentDataGrid의 주변 DataGridRow도 선택됩니다.

ParentDataGrid와 ChildDataGrid가 모두 SelectionChanged 이벤트를 발생시킵니다. ParentDataGrid에서 선택을 취소하려고했습니다. 그러나 ParentDataGrid의 기본 선택이 변경됩니다. 따라서 ParentDataGrid에서 DataGridRow를 선택하지 않는 것이 좋습니다.

핸들 부모 DataGrid에 SelectedCellsChanged 이벤트입니다.

private void DataGrid_SelectedCellsChanged(object sender, SelectedCellsChangedEventArgs e) 
     { 
      DataGridRow row = (DataGridRow)DgrdParent.ItemContainerGenerator.ContainerFromItem(DgrdParent.SelectedItem); 
      if (row != null) 
       row.IsSelected = false; 
     } 

그리고 당신이 선택한 아이 DataGrid을 얻으려면, 당신은 SelectionChanged 이벤트를 사용할 수 있습니다.

<DataGrid x:Name="DgrdParent" ItemsSource="{Binding .}" CurrentCellChanged="DgrdParent_CurrentCellChanged_1" RowDetailsVisibilityMode="Visible" SelectionChanged="DgrdParent_SelectionChanged_1" SelectedCellsChanged="DataGrid_SelectedCellsChanged_1" > 
     <DataGrid.Resources> 
      <Style TargetType="DataGridDetailsPresenter"> 
      </Style> 
     </DataGrid.Resources> 
     <DataGrid.RowDetailsTemplate> 
      <DataTemplate> 
       <DataGrid x:Name="DgrdChild" ItemsSource="{Binding Employees}" SelectionChanged="DataGridInner_SelectionChanged_1" /> 
      </DataTemplate> 
     </DataGrid.RowDetailsTemplate>    
    </DataGrid>

    { 
     System.Diagnostics.Debug.WriteLine("DataGridInner_SelectionChanged_1 > Original source = " + ((DataGrid)sender).Name); 
    }
