You need to use the inserted trigger table to determine what rows were updated. You join to that to update those specific rows. Check out deleted and inserted trigger tables in SQL Server Books Online if you aren't familiar with them.

CREATE TRIGGER utrg_tblTicket
ON [dbo].[tblTicket]
FOR UPDATE
AS

UPDATE t
SET datecomplete = GETDATE()
FROM tblticket t
INNER JOIN inserted i
ON t.YourPKColumn = i.YourPKColumn
