        AxSftTree1.Items.ItemImageExpanded.SetImageListH(ItemImageList.Handle.ToInt64(), 1)
        AxSftTree1.Items.ItemImageLeaf.SetImageListH(ItemImageList.Handle.ToInt64(), 2)

        ' set the column header sort indicators
        AxSftTree1.Headers.SortIndicators = SftTreeHeaderSortIndicatorsConstants.headerSortIndicatorsSftTreeAuto
