The best way to get UltraColumn under the cursor is to utilize MouseUp event of the UltraGrid class. Here is sample in C# but i'm sure you will catch my idea:

private void Grid_MouseUp(object sender, MouseEventArgs e)
{
    UltraGrid Grid = sender as UltraGrid;
    if (Grid.DisplayLayout == null)
        return;
    UIElement ue = Grid.DisplayLayout.UIElement.ElementFromPoint(new Point(e.X, e.Y));
    if (ue == null)
        return;

    UIElement mouseupItem = ue;
    UltraGridColumn mouseupColumn = null;
    UltraGridRow mouseupRow = null;
    UltraGridBand mouseupBand = null;
    ColumnHeader mouseupColumnHead = null;

    mouseupColumn = (UltraGridColumn)ue.GetContext(typeof(UltraGridColumn), true);
    mouseupRow = (UltraGridRow)ue.GetContext(typeof(UltraGridRow), true);
    mouseupBand = (UltraGridBand)ue.GetContext(typeof(UltraGridBand), true);
    mouseupColumnHead = (ColumnHeader)ue.GetContext(typeof(ColumnHeader), true);

    if (mouseupColumnHead != null)
        mouseupColumn = mouseupColumnHead.Column;

    if (e.Button == MouseButtons.Right)
    {
        ShowPopupMenu( mouseupColumn );
        return;
    }
}
