Can someone tell me why my raspberries which were half developed just dried
up? The berries and stems turned brown in so many bunches but other bunches
were fine. It's got me stumped. I have a timer on the sprinkler for each
night.

Did the entire stem with leaves dry up and turn brown or just the fruit?
Raspberries and most other members of the Rubus genus are susceptible to a
soil fungus, Verticillium wilt. Here's a link that explains the problem in
detail with a few, not so great photos:

FWIW, I've seen entire stands of raspberries wiped out by this disease in
just matter of days. Do not replant with the same crop.

Is it only the fruiting canes that were affected, or are the new canes (primocanes)
also browning?

If it is only the fruiting canes, they could have been injured last fall or winter
in various ways (tree crickets laying eggs in the canes is one of the stranger
injuries I've seen).

If the new canes are also dying, it could be verticillium wilt, Phytophthora root rot,
or crown gall.

Here's a raspberry diagnostic page (watch for line wrap):

Wet overnight? you killed them with kindness.
Water the soil not the foliage and do it in the morning so things dry
during the day. When we get a few days rain during the middle of
fruiting the same thing happens. Mulch to keep the soil from
splashing, prune to allow good airflow, plant with good air drainage
like roses , and remove spent canes.
