         getDateTimeGroupOptions(int groupIndex)
      {
         Group group;
         DateTimeGroupOptions datetimeGroup = null;
      
         try
         {
            group = Report.get_DataDefinition()
               .get_Groups().get_Item(groupIndex);
            datetimeGroup = (DateTimeGroupOptions)group.get_GroupOptions();
         }
         catch (Exception e)
         {
            return NULL;
         }
         return datetimeGroup;
      }

      Private Function GetDateTimeGroupOptions _
         (ByVal groupIndex As Integer) As DateTimeGroupOptions
      
         Dim group As Group
         Dim datetimeGroup As DateTimeGroupOptions
         group = Report.DataDefinition.Groups.Item(groupIndex)
         If TypeOf (group.GroupOptions) Is DateTimeGroupOptions Then
            datetimeGroup = group.GroupOptions
            GetDateTimeGroupOptions = datetimeGroup
         else GetDateTimeGroupOptions = nothing
         End If
      End Function
      

  
[C#]
      private DateTimeGroupOptions
         GetDateTimeGroupOptions(int groupIndex)
