    Hi Ahmed,

    You can use the ChildViewExpanding event and collapse the expanded rows:
    private void RadGridView1_ChildViewExpanding(object sender, ChildViewExpandingEventArgs e)
        foreach (var item in radGridView1.Rows)
            if (item != e.ParentRow && item.IsExpanded)
                item.IsExpanded = false;

    I hope this will be useful. Let me know if you have additional questions.
