menu item dropdownheight dynamic

[Piyush]

i want to have a scroll to be added in the submenu item list.
if im making radmenuItem.DropDownHeight = 200, then i can achieve wat want. 
but issue arise when the submenu item are less(say2), then submenuitem list shows 2 submenu item and rest space is show blank, ie. it takes minumun height to the submenu item list as 200.

FUNCTION: 
  private void AddtoReporMenuItem_OnMouseEnter(object sender, MouseEventArgs e)
        {
            var treeViewModel = this.DataContext as TreeViewModel;
            if(radcontextMenu.Items.Count>2)
                radcontextMenu.Items.RemoveAt(2);
            RadMenuItem  reportItem = new RadMenuItem(){Header = "Add to Report"};
            RadMenuItem reportNamesItem;
            RadMenuGroupItem reportsList = new RadMenuGroupItem();
            if (treeViewModel.Reports != null)
            {
                foreach (var report in treeViewModel.Reports)
                {
                    reportNamesItem = new RadMenuItem();
                    reportNamesItem.Header = report.ReportName;
                    reportNamesItem.Click += (senderObj, eventargs) => reportItem_Click(senderObj, eventargs, report);
                    reportsList.Items.Add(reportNamesItem);
                }
               
                reportItem.Items.Add(reportsList);
                reportItem.DropDownHeight = 200;
                radcontextMenu.Items.Add(reportItem);
            }

        }




xaml:
   <telerik:RadContextMenu.ContextMenu>
                <telerik:RadContextMenu x:Name="radcontextMenu" MouseEnter="AddtoReporMenuItem_OnMouseEnter">
                    <telerik:RadMenuItem Header="{localization:Translate DeleteTxt}" Command="{Binding Path=DeleteChartDash}" />
                    <telerik:RadMenuItem Header="{localization:Translate ExportButton}">
                        <telerik:RadMenuItem Header="CSV" Command="{Binding Path=ExportCommand}" CommandParameter="ExportChart" />
                        <telerik:RadMenuItem Header="{localization:Translate ExportdataTxt}" Command="{Binding Path=ExportCommand}" CommandParameter="ExportData"  />
                        <telerik:RadMenuItem Header="{localization:Translate PowerPointTxt}" Command="{Binding Path=ExportCommand}" CommandParameter="ExportPPT"  />
                        </telerik:RadMenuItem>
                </telerik:RadContextMenu>
