从Datagrid加载图像

Question

我将数据加载到DataGrid控件中（dataGridImagem使用此代码：

private bool carregarDados()
{
    bool status = false;
    try
    {
        ligacaoBD.Open();
        MySqlCommand comandoMySQL = new MySqlCommand("Select * from imagem", ligacaoBD);
        MySqlDataAdapter adp = new MySqlDataAdapter(comandoMySQL);
        DataSet ds = new DataSet();
        adp.Fill(ds, "carregarDados");
        dataGridImagem.DataContext = ds;
        status = true;
    }
    catch (MySqlException ex)
    {
        MessageBox.Show(ex.ToString());
    }
    finally
    {
        ligacaoBD.Close();
    }
    return status;
}

XAML看起来像这样：

<DataGrid Grid.Row="0" AutoGenerateColumns="False" VerticalScrollBarVisibility="Auto" HorizontalAlignment="Left" Name="dataGridImagem" ItemsSource="{Binding Path=carregarDados}" Margin="5" SelectionMode="Single" CanUserAddRows="False" CanUserDeleteRows="False" >
<DataGrid.Columns>
    <DataGridTextColumn Binding="{Binding Path=idImagem}" Header="Código" Width="Auto" IsReadOnly="True" />
    <DataGridTemplateColumn Header="Imagem"  IsReadOnly="True" Width="Auto">
        <DataGridTemplateColumn.CellTemplate>
            <DataTemplate>
                <Image Source="{Binding imagemImagem}" Width="10" />
            </DataTemplate>
        </DataGridTemplateColumn.CellTemplate>
    </DataGridTemplateColumn>
    <DataGridTextColumn Binding="{Binding Path=imagemDescricao}" Header="Imagem" Width="*" IsReadOnly="True" />
</DataGrid.Columns>
<DataGrid.RowDetailsTemplate>
    <DataTemplate>
        <Image Height="100" Source="{Binding imagemImagem}" />
    </DataTemplate>
</DataGrid.RowDetailsTemplate>

如何将与所选记录关联的图像加载到图像控件中？
