Show missing Type and count as 0 using t-sql

Question

Hi All,
I have a table with 3 columns, let say  EventSchedule,ScheduleType,Count
EventSchedule      ScheduleType     Count
Conference            Type1         25
Meeting               Type1         20
Meeting               Type2         22
Appointment           Type1         40
Appointment           Type2         35
Appointment           Type3         55
I want t-sql to show output like this..
EventSchedule      ScheduleType     Count
Conference            Type1         25
Conference            Type2         0
Conference            Type3         0
Meeting               Type1         20
Meeting               Type2         22
Meeting               Type3         0
Appointment           Type1         40
Appointment           Type2         35
Appointment           Type3         55
Presentation          Type1         0
Presentation          Type2         0
Presentation          Type3         0
Note:
1)The EventSchedule column will always have values - Conference,Meeting,Appointment,Presentation         
2)The ScheduleType  column will always have values- Type1,Type2,Type3
In the above sample source data ,there was no Type2, Type3 for Conference and there was no Type3 for Meeting and there was no Type1 , Type2 and Type3 fpr Presentation. So whenever if any Type is missing it should populate that missing Type  with count
as 0.
Create statement;
Create Table Sample (EventSchedule varchar(20) null,ScheduleType varchar(10) null,Count int null)
Insert statement:
Insert into sample (EventSchedule,ScheduleType,Count) Values ('Conference','Type1',25)
Insert into sample (EventSchedule,ScheduleType,Count) Values ('Meeting' ,'Type1',20)
Insert into sample (EventSchedule,ScheduleType,Count) Values ('Meeting','Type2',22)
Insert into sample (EventSchedule,ScheduleType,Count) Values ('Appointment','Type1',40)
Insert into sample (EventSchedule,ScheduleType,Count) Values ('Appointment' ,'Type2',35)
Insert into sample (EventSchedule,ScheduleType,Count) Values ('Appointment','Type3',55)
Thanks!

Hi HoroChan-
This is the solution I found. I created 2 cte's. In first CTE I created the list with 1 to 12 numbering and did left join with the second cte(source data).
WITH myListCTE AS (
SELECT 'Conference' AS EventSchedule ,'Type1' AS ScheduleType, 1 AS Rn
UNION ALL    
SELECT 'Conference' AS EventSchedule, 'Type2' AS ScheduleType, 2 AS Rn 
UNION ALL       
SELECT 'Conference' AS EventSchedule, 'Type3' AS ScheduleType, 3 AS Rn         
UNION ALL
SELECT 'Meeting' AS EventSchedule,'Type1' AS ScheduleType, 4 AS Rn   
UNION ALL     
SELECT 'Meeting' AS EventSchedule,'Type2' AS ScheduleType, 5 AS Rn 
UNION ALL       
SELECT 'Meeting' AS EventSchedule,'Type3' AS ScheduleType, 6 AS Rn        
UNION ALL
SELECT 'Appointment' AS EventSchedule,'Type1' AS ScheduleType, 7 AS Rn
UNION ALL         
SELECT 'Appointment' AS EventSchedule ,'Type2' AS ScheduleType, 8 AS Rn      
UNION ALL  
SELECT 'Appointment' AS EventSchedule,'Type3' AS ScheduleType, 9 AS Rn    
UNION ALL
SELECT 'Presentation' AS EventSchedule,'Type1' AS ScheduleType, 10 AS Rn
UNION ALL         
SELECT 'Presentation' AS EventSchedule,'Type2' AS ScheduleType, 11 AS Rn
UNION ALL        
SELECT 'Presentation' AS EventSchedule,'Type3' AS ScheduleType, 12 AS Rn         
, myCTE AS (
SELECT EventSchedule,ScheduleType, Count
, Case WHEN EventSchedule='Conference' AND ScheduleType='Type1' THEN 1
       WHEN EventSchedule='Conference' AND ScheduleType='Type2' THEN 2
       WHEN EventSchedule='Conference' AND ScheduleType='Type3' THEN 3
       WHEN EventSchedule='Meeting' AND ScheduleType='Type1' THEN 4
       WHEN EventSchedule='Meeting' AND ScheduleType='Type2' THEN 5
WHEN EventSchedule='Meeting' AND ScheduleType='Type3' THEN 6
WHEN EventSchedule='Appointment' AND ScheduleType='Type1' THEN 7
WHEN EventSchedule='Appointment' AND ScheduleType='Type2' THEN 8
WHEN EventSchedule='Appointment' AND ScheduleType='Type3' THEN 9
WHEN EventSchedule='Presentation' AND ScheduleType='Type1' THEN 10
WHEN EventSchedule='Presentation' AND ScheduleType='Type2' THEN 11
WHEN EventSchedule='Presentation' AND ScheduleType='Type3' THEN 12
END AS NewRn
FROM Sample
SELECT mlc.EventSchedule,mlc.ScheduleType,ISNULL(mc.Count,0) AS Count,mlc.Rn
FROM myListCTE mlc
LEFT JOIN myCTE mc on mc.NewRn=mlc.Rn
ORDER BY mlc.Rn
Thanks!
