Change Hierarchy Descriptor on runtime

It is possible to set new Level Descriptors on Runtime? The code below do not work. I dont know the reason why the pivot grid do not refresh the hierarchy

        private void ChangePeriodType(BusinessObjects.Constant.BudgetPeriodType type)
            if (this.MyDateLevels != null && this.MyDateLevels.Count == 4 && this.MyDateDescriptor !=null)
                switch (type)
                    case Constant.BudgetPeriodType.Quarterly:
                    case Constant.BudgetPeriodType.Yearly:
            Hierarchy = new HierarchyDescriptor<BudgetMainViewModel>(p => p.Date);
            Hierarchy.AppliesToPropertiesOfType = typeof(DateTime?);
            Hierarchy.AddLevel<DateTime?>(p => "Date", "Date");
            Hierarchy.AddLevel<DateTime?>(p => p.GetValueOrDefault().Year, "Year");
            Hierarchy.AddLevel<DateTime?>(p => p.GetValueOrDefault().QuarterShort(), "Quarter");
            Hierarchy.AddLevel<DateTime?>(p => p.GetValueOrDefault().MonthShort(), "Month");
            Expression<Func<DateTime?, int>> expression = (p => p.GetValueOrDefault().Month);
            Hierarchy.LevelDescriptors[3].OrderByKeyExpression = expression;
            Hierarchy.HierarchyDisplayName = "Date";
            this.MyDateDescriptor = Hierarchy;
            this.MyDateLevels = new List<HierarchyLevelDescriptor>(Hierarchy.LevelDescriptors);

    Hello Roman,

    After looking into this and doing some research, "Change Hierarchy Descriptor on runtime" has been determined to be a new product idea. You can suggest new product ideas for future versions (or vote for existing ones) at

    There are many benefits to submitting an product idea:

    4. “Include a link to this thread” in your idea so product management will be able to look back at this case.
