Share Point Calendar RecurrenceData to Simple readable string Edit Recurence.

Question

Hi All,
I am updating recurrence event occurrence using custom Web part.
So now everything is working fine apart from this one Text showing for recurrence Display.
When I Use this line  of code then output is as below.
nItem["RecurrenceData"] = oldItem["RecurrenceData"].ToString();
When I don't set anything for RecurrenceData then its show as below.
<!-- #RENDER FAILED -->
So my question is how can we get the following output.
I'm using this line of code to update Recurrence occurrence event by code.
     public static void UpdateInstanceFromRecurringSeries(SPWeb web, String listname, string recurID)
            string[] splitvals = recurID.Split('.');
            string itemid = splitvals[0];
            SPList calendarList = web.Lists[listname];
            DateTime calendardate = DateTime.Now;
            DateTime eventdate = calendardate;
            DateTime enddate = calendardate;
            if (splitvals[1] == "0")
                calendardate = Convert.ToDateTime(splitvals[2]);
                eventdate = calendardate;
                enddate = calendardate;
            else
                if (splitvals[1] == "1")
                    SPListItem CItem = calendarList.GetItemById(Convert.ToInt32(itemid));
                    eventdate = Convert.ToDateTime(CItem["EventDate"]);
                    enddate = Convert.ToDateTime(CItem["EndDate"]);
            if (calendarList != null)
                // Construct a query that expands recurring events
                SPQuery query = new SPQuery();
                query.ExpandRecurrence = true; //*** important ***
                query.Query = "<Where><DateRangesOverlap><FieldRef Name=\"EventDate\" /><FieldRef Name=\"EndDate\" />" +
                    "<FieldRef Name=\"RecurrenceID\" /><Value Type=\"DateTime\"><Month /></Value></DateRangesOverlap><Eq><FieldRef Name=\"ID\"
/><Value Type=\"Integer\">" + itemid + "</Value></Eq></Where>";
                SPListItemCollection calendarItems = calendarList.GetItems(query);
                foreach (SPListItem li in calendarItems)
                    if (li.RecurrenceID.ToString().Equals(recurID) && (li.ID.ToString().Equals(itemid)))
                        eventdate = Convert.ToDateTime(li["EventDate"]);
                        enddate = Convert.ToDateTime(li["EndDate"]);
                        web.AllowUnsafeUpdates = true;
                        SPListItem nItem = calendarList.Items.Add();
                        nItem["MasterSeriesItemID"] = li.ID;
                        nItem["UID"] = li["UID"];
                        nItem["EventType"] = 4;
                        nItem["fRecurrence"] = true;
                        nItem["fAllDayEvent"] = Convert.ToBoolean(li["fAllDayEvent"]);
                        nItem["EventDate"] = eventdate.AddHours(1); ;
                        nItem["EndDate"] = enddate.AddHours(1);
                        nItem["RecurrenceID"] = li["RecurrenceID"];
                        nItem["Title"] = "Update:" + Convert.ToString(li["Title"]);
                        nItem["Recurrence"] = li["Recurrence"];
                        nItem["TimeZone"] = li["TimeZone"];
                        nItem["Duration"] = (enddate.TimeOfDay - eventdate.TimeOfDay).TotalSeconds;
                        nItem.Update();
                        calendarList.Update();
                        web.AllowUnsafeUpdates = false;
                        break;
