Hi Can someone help me how to know on what cell user click with his mouse?

private void GridMouseDoubleClick(object sender, MouseButtonEventArgs e)

        {

DependencyObject source = e.OriginalSource as DependencyObject;

            if (source == null)

            {

                return;

            }

            if (source is FrameworkElement)

            {

                DataRecordPresenter drp = Infragistics.Windows.Utilities.GetAncestorFromType(source, typeof(DataRecordPresenter), true) as DataRecordPresenter;

                if (drp == null)

                {

                    return;

                }

                if (drp.Record != null)

                {

                    drp.Record.IsSelected = true;

                    drp.IsActive = true;

                    DataRecord r = drp.DataRecord;

                    if (r != null)

                    {

                    }

                }

            }

}
