Using VNAV for takeoff/ascent?

Im currently using VNAV in the Cessna Caravan (with latest G1000 NXI mod) and I understand how it works for the descent but I was wondering if its ever used for taking off/climbing to cruise altitude ?

With descents it always tells you what altitude you should be at in the flight plan but there is never any info about what attitudes I should be at during the various waypoints on take off/ascent. Where does one get this information ?

Is VNAV even used on takeoff/ascent in real world ?
