how can i run sqlserver trigger from C#

I have multiple trigger in a single sqlserver table some create description of a product by concatenating different fields, some get data from another table and a trigger which insert a product to another table.

I want to run the trigger which insert's data to another database table on button click from C#.

here is my code which inserts or setup product into another table

Create  TRIGGER [dbo].[WHL-MISYSSETUP] 
    ON [dbo].[WHEELS]
    AFTER insert,UPDATE
    AS 
    BEGIN
     IF TRIGGER_NESTLEVEL() > 1
     RETURN

           BEGIN
   IF NOT EXISTS (SELECT * FROM [MITESTCO].dbo.[MIITEM]  
                   WHERE [MITESTCO].dbo.[MIITEM].itemId IN (select [STOCK NO] from inserted) and [MITESTCO].dbo.[MIITEM].descr IN  (select [PURCHASE DESCRIPTION] from inserted))

  BEGIN
 INSERT INTO [MITESTCO].dbo.MIITEM
   ([itemId], [descr],[xdesc],[sales] ,[uOfM] ,[poUOfM] ,[uConvFact],[ref],[type],[status])--,[unitWgt] 
 SELECT [STOCK NO], [PURCHASE DESCRIPTION2], [SALES DESCRIPTION2], [STOCK NO] ,'EA' ,'EA' ,'1',[WORK INSTRUCTION-WHL], '2','0'--,[APPROX. WGT.]
  FROM [inserted]
 WHERE [STOCK NO] NOT IN (SELECT [itemId] FROM [MITESTCO].dbo.[MIITEM] WHERE itemId NOT LIKE '*-CI')
 AND [MAKE / BUY]='Make';
 END

 END
    SET ANSI_WARNINGS  ON;



        SET ANSI_WARNINGS  off;
           BEGIN
   IF NOT EXISTS (SELECT * FROM [MITESTCO].dbo.[MIITEM]  
                   WHERE [MITESTCO].dbo.[MIITEM].itemId IN (select [STOCK NO] from inserted) and [MITESTCO].dbo.[MIITEM].descr IN  (select [PURCHASE DESCRIPTION] from inserted))

The main reason that i want to run it manually or on button click event is because for some reason this trigger run before computed fields and some of the triggers so i don't get complete information to insert to the other table for the first time both after insert or update. i tried EXEC sp_settriggerorder @triggername=N'[dbo].[WHL-MISYSSETUP]', @order=N'Last', @stmttype=N'INSERT' but that doesnt help me i get the same problem

when new product created or updated i want to run this from C# on button click_event. Any idea will appreciated
