I am new to Dynamics CRM and I could not find any information so far that would apply to my scenario. We have a Program entity that can have/reference multiple program dates entities, and each program date can have/reference multiple event entities. We have a view displaying all events associated with the program, and on the program form we want to display in a text the total number of events. From the view user can select multiple events then click delete button. This is a button that comes with CRM, not a custom one.
If I create a plugin for Delete message on event entity and want to query both program and Program date filed that keeps the total number of events then subtract one I am not sure these plugins will execute in sequence or concurrently thus having a race condition.
Now using javascript I also do not know if it is possible to read entity records PK and hook up into the pop up Confirm Deletion dialog box and execute after that a web service call
Any ideas?
Thanks Dan
