Programmatically Updating a document library in Sharepoint

Question

Im quite new to SHarepoint. I have a requirement like, i need to move some documents from different document libraries to a document library named "Region". So that each time a document is updated in these document libraries , the document should be updated in the library "Region" as well. I wrote a c# function in a class library,to copy the documents to the library and added the dll to that sites Bin folder.Function is working fine. But Im stuck up , Im n ot sure where to call this function.In which event should i write it, so that each time any of these documents are modified, that change has to be reflected in the "Region" library .

Answer 1

You have to create a SharePoint event handler and attach it to all the document libraries where you change the documents. You will then override the ItemAdded and ItemUpdated methods to perform the copying.
