help to customize List/Calendar objects

[attila79]

Hello,

I am a new developer in WSS 3.0 and I need some help using it...

I have been asked to develope an appointment calendar where it should be
activated some validation rules (I am going to use Windows SharePoint Services 3.0 to

develope this software) during insert/update/delete events.

For example:
- it can't be possible insert date in a specific range (holidays, weekend, or date

minor of the current date)
- each day can have maximum 20 events.
- when one item is inserted, later it could be possible that automatically one event is

moved to another day if some conditions are true (there is a priority validation that

decide if an item should be moved to another day).

I was thinking to use a CUSTOM LIST and add the VIEW Calendar but I cant figure out how

I can customize it programmatically. The same problem happens If i use the Calendar

Object already available..I cant understand how to add the validation rules

programmatically...


- How can I insert a validation in Insert/Update/delete event using a custom list or a

calendar?
- is it possibile colour some events inserted in the calendar depending of the value

that a specific field can assume? For example if field(A) = 1 then use colour "Red", if

field(A)=2, then use colour "Green" etc

thank you for any advice...
