Answer 1

private void DataGrid_MouseDoubleClick(object sender, MouseButtonEventArgs eventArgs)
{
    if (sender == null) return;
    if (eventArgs.ButtonState != MouseButtonState.Pressed) return; //only react on pressed

    var dataGrid = sender as DataGrid;
    if (dataGrid == null || dataGrid.SelectedItems == null) return;

    if (dataGrid.SelectedItems.Count == 1)
    {
        var simplePension = dataGrid.SelectedItem as ISimplePension;
        if (simplePension != null)
        {
            DataFetcherHolder.DataFetcher.SelectPension(simplePension);
            Execute(EditSelectedPensionFunction);
        }
    }
}
