Duplicate List records

How do I avoid entering the same kind of data from the same users in sharepoint开发者_如何学运维 list?

Any directions please Hari Gillala

No luck going the easy way with Sharepoint 2007. With Sharepoint 2010 you have the choice to make values unique (see SharePoint 2010 – Enforce Unique Values).

With Sharepoint 2007 you have to do that programmatically using an EventReceiver. See following post for lot's of information: How to avoid duplicate record depending on the field in customlist
