Question

I have a WPF application that contains a datagrid. It is bound to my List object \"Orders\" shown below.

public class OrderBlock
{
  public Settings setting;

I'v used the MouseDoubleClick:

    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);
            }
        }
    }

When you double-click a data grid, the row is also selected, so I simply find the selected item and use it.
