Indicator if child row has data?

[Jon]

When the grid control displays its data, the child rows are collapsed and the user needs to click on the arrow to the left to expand it and the only way a user knows if a row has child data is to expand it.  Is there a way to have the expand arrow (or some other way) display a different color if there are child rows?  I don't want to expand every child row as that would make it difficult for the users to quickly find the data they want.

Hello,

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

    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;
                        //cell.BackColor = System.Drawing.Color.Red;
                    }
                    nestedViewItem.Visible = false;
                }
                if (nestedView.HasDetailTables)
                {
                    HideExpandColumnRecursive(nestedView);
                }
            }
        }
    }
