    if (e.MenuType == TreeListMenuType.Column) {
        popupMenu_Column.Tag = e.HitInfo;
        popupMenu_Column.MenuCaption = $"{e.HitInfo.Column}";

TreeListHitInfo GetHitInfo(BarItemLink link) {
    PopupMenu menu = link.LinkedObject as PopupMenu;
    return menu.Tag as TreeListHitInfo;
void barButtonItem_Filter_ItemClick(object sender, DevExpress.XtraBars.ItemClickEventArgs e) {
    TreeListHitInfo info = GetHitInfo(e.Link);

void barButtonItem_ColumnChooser_ItemClick(object sender, DevExpress.XtraBars.ItemClickEventArgs e) {
