Rather than a trigger, can you change the table so that Full_Name is a calculated column?

+1
A calculated column is far better here than a trigger for a number of reasons.

Agreed.
For example:
ALTER TABLE dbo.tablename
DROP COLUMN Full_Name;
ALTER TABLE dbo.tablename
ADD Full_Name AS CAST(ISNULL(F_Name + ' ', '') + ISNULL(Lname, '') AS varchar(100))
-- change 100 to whatever max length you want for the column

It would take a little more space but I recommend adding the PERSISTED hint.

For me, it depends, mostly on how and/or how often the full_name was used.
