Rendering of SharePoint controls base on user permission

The SharePoint server control SPSecurityTrimmedControl can be used to control rendering of page elements/components base on user’s permission. The PermissionsString  property can be used to specify users with what permissions are allowed viewing of the page element/components within. For a list of possible PermissionsString, refer to http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.webcontrols.spsecuritytrimmedcontrol.permissionsstring.aspx.
