    if(e.RowKind != DevExpress.Web.ASPxTreeList.TreeListRowKind.Data) return;
    ASPxImage img = ASPxTreeList1.FindDataCellTemplateControl(e.NodeKey,
      ASPxTreeList1.Columns["Product"] as TreeListDataColumn, "ASPxImage1") as ASPxImage;
    ASPxLabel lb = ASPxTreeList1.FindDataCellTemplateControl(e.NodeKey,
      ASPxTreeList1.Columns["Product"] as TreeListDataColumn, "ASPxLabel1") as ASPxLabel;
