Allow or prevent Contributors ability to edit scriptable Web Parts (SharePoint Server 2010)

SharePoint 2010
 

Applies to: SharePoint Server 2010, SharePoint Foundation 2010

Topic Last Modified: 2011-06-24

In SharePoint Server 2010, Web Parts are categorized as to whether or not users with the Contribute permission level can add or modify JavaScript.

Users who have the default Contribute permissions level cannot add or modify scriptable Web Parts. This is because the scriptable Web Parts are marked as “unsafe against Contributor scripting” in a web.config file by default and the default setting in Central Administration is “Prevent contributors from adding or editing scriptable Web Parts”. However, when the scriptable Web Parts are marked as “unsafe against Contributor scripting”, a member of the Farm Administrators group can change the Web Part Security setting in Central Administration to allow users with the Contribute permission level to edit scriptable Web Parts.

Developers can set scriptable Web Parts to “safe against Contributor scripting” in a web.config file. In this situation, the scriptable Web Parts can be edited by users with the Contribute permission level without any actions by a member of the Farm Administrators group. For more information about these safe Web Parts, see the "About editing Web Parts" section in Contribute permission level overview (SharePoint Server 2010).

The following table shows the effective behavior of a given Web Part with different settings from developers and a member of the Farm Administrators group.
