<DataGrid AutoGenerateColumns="True" Margin="10,174,12,35" Name="dataGridArchiveQueue" Visibility="Visible" 
AlternatingRowBackground="#01000000" 
BorderBrush="#FF688CAF" 
HorizontalGridLinesBrush="#37000000" 
VerticalGridLinesBrush="#37000000" 
CanUserAddRows="False"

IsReadOnly="True" 
SelectedItem="{Binding SelectedItemArchiveGrid}" Grid.ColumnSpan="2">
     <DataGrid.Resources>
          <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}"
                                                         Color="LightBlue" />

このデータグリッドに次のデータを入力します。

            using (var connection = new SqlConnection(GetConnectionString()))
            {

                {
                    connection.Open();

                    cmd.Parameters.AddWithValue("status", status != "Anything" ? status : "");
                    cmd.Parameters.AddWithValue("source_library", sourceLibrary != "Anything" ? sourceLibrary : "");
                    cmd.Parameters.AddWithValue("destination_library", destinationLibrary != "Anything" ? destinationLibrary : "");


                    using (var reader = cmd.ExecuteReader())
                    {
                        var dt = new DataTable();
                        dt.Load(reader);

                        connection.Close();
                        return dt.DefaultView;
                    }
                }
            }
        }

ボタンを使用して編集または削除できるように、選択した行の内容を取得しようとしています。これを行うために、私は次のプロパティを持っています：

public DataView SelectedItemArchiveGrid { get; set; }

ただし、現在選択されているアイテムの詳細を取得するためにこのプロパティにアクセスする方法がわかりません。

SelectedItemArchiveGridのバインディングプロパティタイプをDataViewからDataRowViewに変更する必要があり、バインディングにはXAMLでRelativeSourceを使用する必要があります

XAML

SelectedItem="{Binding DataContext.SelectedItemArchiveGrid, RelativeSource={RelativeSource AncestorType={x:Type UserControl}, Mode=FindAncestor}}"

C＃

private DataRowView _selectedItemArchiveGrid;
public DataRowView SelectedItemArchiveGrid
{
    get
    {
        return _selectedItemArchiveGrid;
    }
    set
    {
        _selectedItemArchiveGrid = value;
    }
}
