Asha - it is conceptually possible to do this.  However there are a number of things to consider:

1. should status=cancelled also be strike through
2. if you are going to use strike through to show one type of status, should there be a way of showing pending vs checked-in vs ...

1 is easy - Yes

2 illustrates the problem is partially addressed by the Highlight By facility. However, this then leads to the problem that if you want to highlight by event then you cannot also distinguish all the statuses.

We address the problem by a) highlighting by event; b) showing the status by n '=xx' coding where xx is the 1st two characters of the status code.

eg

This is done using the schedule view expression:

concat(substring(concat(openvpms:get(., 'clinician.name'),': ', openvpms:get(., 'patient.name'),' ',openvpms:get(.,'customer.objectReference.lastName'),' =',substring(openvpms:get(.,'act.status'),1,2)),1,30),'\n', substring(concat('[',openvpms:lookup(openvpms:get(., 'patient.objectReference'),'breed'),']'),1,30),'\n', substring(concat(openvpms:get(.,'scheduleType.name'), ':', openvpms:get(.,'act.reasonName'),' ', openvpms:get(.,'waiting')),1,30))

Note that we use 'short names' for the vets - eg Dr Joe Bloggs has a clinician.name of JB and a clinician.description of 'Dr Joe Bloggs'. Hence the openvpms:get(.,'clinician.name') returns either nothing (if the clinician has not been set in the appointment or the 2 character name if it has.

Note also the 11-11.30 appointment - our approach to blocking out part of the schedule.

This approach is of course a work-around. 

I do like the idea of using strike through to indicate 'all done', ie complete or cancelled.
