is it possible for us to filter the sharepoint calendar list based on the entered start time & end time in the nintex form either using the formula or list lookup option in the form?
it's not possible with lookup control nor with lookup function. they both support only simple single condition for equality.
I guess it might be possible with web request control, if you are on enterprise license.
Thanks for your replied.
I wanted to use sharepoint calendar as our meeting room booking. but the current calendar allow overlapped booking (events).
do you have any suggestion on this ?
you could make the overlapping check with a workflow. there you'd have much more flexibility.
consider it just like user is requesting to book a room. but booking is performed by a workflow.
if there is no other overlapping event, workflow writes new event to the calendar and sends confirmation. if it overlaps with already booked event workflow would send a reject notification.
just like outlook does...
