devexpress - winforms - xtragrid - 对未绑定列数据进行过滤会抛出NullReference异常

Question

我有一个xtragrid，我填充并有2个未绑定的列。一切正常，除非我去过滤列，过滤的弹出窗口正确显示但是当我双击一个值时，我得到一个nullreference异常。我设法找到异常的位置，它在我的方法CustomColumnUnboundData中，我尝试从当前行获取当前对象，对象为null。你能帮助我吗？我究竟做错了什么 ？ e.ListSourceRowIndex或GetRow（）似乎不能用于过滤...

     private void gridView1_CustomUnboundColumnData(object sender, CustomColumnDataEventArgs e)
    {
        GridView gridView = (GridView)sender;

        int dataSourceIndex = e.ListSourceRowIndex;

        Person person = (Person)gridView.GetRow(dataSourceIndex);

        if (e.Column.FieldName == "name" && e.IsGetData)
        {
            e.Value = person.PersonKey.Name;
        }

        if (e.Column.FieldName == "surname" && e.IsGetData)
        {
            e.Value = person.PersonKey.Surname;
        }
    }

            Person person = e.Row as Person;
//...
