90 Chapter 3 Working with Lists and Libraries
For example, in the browser, when you display an Announcements list and then select
the arrow to the right of an announcement item, the list item menu contains the actions
View Item, Edit Item, Alert Me, Manage Permissions, and Delete Item. On a site created
using SharePoint Server, additional actions are displayed, such as Compliance Details.
These default actions are also associated with a sequence number. The sequence numbers
for the default actions are not visible in SharePoint Designer, but with some testing
you can discover them by trying different numbers as the sequence number when you
add your own actions. For example, if you want users to quickly create a new Task item
by using the Tasks list’s NewForm.aspx page, choose a sequence number of 50 to place
the New Task Item action at the top of the item menu. A sequence number of 2,000
places the New Task Item action below the Delete Item action. To create the New Task
Item action between the Edit Item and Alert Me actions, choose a sequence number between
300 and 1,000.
When you define your custom action, you can also specify a Rights Mask that defines
which users can see the custom action. The Rights Mask can contain any of the
SPBasePermission member names that are listed at http://msdn.microsoft.com/en-us/
library/microsoft.sharepoint.spbasepermissions.aspx. When you want the custom action to
appear for any user of the list, leave the Rights Mask empty or type EmptyMask.
Using SharePoint Designer, you cannot remove a custom action, add other forms of
actions (such as check boxes, combo boxes, drop-down lists, text boxes, and flyout anchors),
or add tabs or groups. Developers can create such actions and extend the server
ribbon on pages other than the view and form pages, as well as the list item menu, by
creating a feature in Visual Studio 2010 with the SharePoint Ribbon project template,
which can be found at http://code.msdn.microsoft.com/vsixforsp. This Web site also contains
a hands-on lab and a walkthrough video.
In this exercise, you upload new image files to the Site Assets library and then use those
images when you add a custom action to a list item menu.
SET UP Using SharePoint Designer, open the team site you used in the previous
exercise, if it is not already open.
Import Files
1. In the Navigation pane, click Site Assets, and then click Import Files in the New
group on the ribbon.
The Import dialog box opens.
2. Click Add File to display the File Open dialog box.
