view running slower than query

using sql 2008 R2.

I have a query which runs in less then 1 sec.

I created a view with the same sql and run this view with the same where clause that I am using with the query above, but it took over 7 minutes. Why is my view so slow if the query performance is good? Any ideas?

and there is no difference of any kind between the query SQL and the view SQL?
same tables/database?
same user?
no order by in the view?

Provide the view's SQL please.

Do you have an explain plan? attach it if you do

I figured out that when I do a where clause in the sql, it is before the group by, but the view does it after the group by. I needed the group by in the view for some aggregations on some columns in one of the left join. So I changed it to do the aggregation in a subquery, and do the left join to the sub query, which solved my problem.

Now both sql and view return results in a fraction of a sec.
