Workflow lock "edit item"

Is it possible to disable "edit item" in a Sharepoint List when a custom workflow is running? May开发者_开发知识库be a property in the workflow that can be affected?

Thanks, David Esteves

You can use a custom activity to set read-only permissions on the item in the beginning of the WF and then to restore the original permissions in the end. Take a look at this selection of custom activities at CodePlex: link text
