Hello,

public static void HideExpandColumnRecursive(GridTableView tableView)
    {
        GridItem[] nestedViewItems = tableView.GetItems(GridItemType.NestedView);
        foreach (GridNestedViewItem nestedViewItem in nestedViewItems)
        {
            foreach (GridTableView nestedView in nestedViewItem.NestedTableViews)
            {
                if (nestedView.Items.Count == 0)
                {
                    System.Web.UI.WebControls.TableCell cell = nestedView.ParentItem["ExpandColumn"];

                    if (cell.Controls.Count == 0)
                    {
                    }
                    else
                    {
                        cell.Controls[0].Visible = false;
                    }
                    nestedViewItem.Visible = false;
                }
                if (nestedView.HasDetailTables)
                {
                    HideExpandColumnRecursive(nestedView);
                }
            }
        }
    }


  protected void RadGrid1_PreRender(object sender, EventArgs e)
    {
        HideExpandColumnRecursive(RadGrid1.MasterTableView);
    }

Let me know if any concern.
