Limit activation of DataGrid.RowDetailsTemplate to certain columns

Have a DataGrid with multiple columns.
Would like to limit activation of the DataGrid.RowDetailsTemplate to certain columns.
Actually I just want to exclude one column from activating the DataGrid.RowDetailsTemplate.

You can use RowDetailsVisibilityChanged event (msdn) and in event handler you can check selected column and hide or show row details.

In example below I don't want to show row details when I select cell in column "Name".

XAML:

<DataGrid Name="outerGrid" AutoGenerateColumns="False"                 
          ItemsSource="{Binding}"                  
          RowDetailsVisibilityChanged="outerGrid_RowDetailsVisibilityChanged" >
    <DataGrid.RowDetailsTemplate>
        <DataTemplate>
            <DataGrid Name="innerGrid" ItemsSource="{Binding Items}" AutoGenerateColumns="False" >
                <DataGrid.Columns>
                    <DataGridTextColumn  Header="ID" Binding="{Binding Id}"/>
                    <DataGridTextColumn  Header="Name" Binding="{Binding Name}"/>
                    <DataGridTextColumn  Header="Surname" Binding="{Binding Surname}"/>
                </DataGrid.Columns>
            </DataGrid>
        </DataTemplate>
    </DataGrid.RowDetailsTemplate>
    <DataGrid.Columns>
        <DataGridTextColumn  Header="ID" Binding="{Binding Id}"/>
        <DataGridTextColumn  Header="Name" Binding="{Binding Name}"/>
        <DataGridTextColumn  Header="Surname" Binding="{Binding Surname}"/>
    </DataGrid.Columns>
</DataGrid>

Code-behind:

private void outerGrid_RowDetailsVisibilityChanged(object sender, DataGridRowDetailsEventArgs e)
{
    DataGrid dg = sender as DataGrid;
    if (dg != null)
    {
        if (dg.CurrentCell != null && dg.CurrentCell.Column.Header.ToString() == "Name")
        {                    
            e.DetailsElement.Visibility = System.Windows.Visibility.Collapsed;
        }
        else
        {   
            e.DetailsElement.Visibility = System.Windows.Visibility.Visible;
        }
    }
}
