        AxSftTree1.BulkUpdate = True

        ' set default item graphic.  This can also be done at design time
        AxSftTree1.Items.ItemImageExpandable.SetImageListH(ItemImageList.Handle.ToInt64(), 0)
        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
        AxSftTree1.get_Header(0).SortIndicator = SftTreeSortIndicatorConstants.sortIndicatorSftTreeAscending
