Prevent SharePoint list item deletion

Question

How can I prevent users from deleting sharepoint task list item? Should i override the ItemDeleting event or is there any other site level options available to achieve the same?

Answer 1

You could also set up a custom permission level out of the box.

1. Navigate to your Site Collection (if you're in a subsite, you can go to Site Actions -> Site Settings -> Go to top level site settings)
2. Site Actions -> Site Settings -> Advanced permissions
3. Click Settings -> Permission Levels
4. Click Add a permission level

I would recommend using the existing "Contribute" permission level as a guide and just uncheck the "Delete Items" list permission. Then, you can give your users that permission to the list.
