Adding Custom Actions to the List Item Menu in SharePoint 2010 Using SharePoint Designer 2010[Sharepoint中添加自定义菜单]

In SharePoint 2010, it is easier than ever to add custom actions that are
scoped to a specific list using SharePoint Designer 2010. So today, I am going
to walk you through the process.

In a related post on my
blog

, I showed you how to surface ULS logs using SharePoint
Designer 2010, an External Content Type, and an External List. We’re going to
use that list as our base for our custom action.

Our phony business case for this custom action is such – We are surfacing our
ULS logs into a SharePoint list, and want to collect feedback on specific log
entries for later consumption. We need to link to a form elsewhere in the site,
which we will pass a reference to the item in question, as a URL.

Note – the List Item Menu refers to the same thing as the Edit Control Block.
This is the context menu which is associated with all list items, available in
list views and list view web parts.

So, let’s open SharePoint Designer 2010, and navigate to our ULS Logs list,
and we’re going to select Custom Action > List Item Menu

from the Custom Action
button on the ribbon UI



Once we select that link, we are presented with the following form



We’re going to name our custom action Log Entry
Comment

, and give it a description as well. Now let’s scroll down.
You will see that we have 3 different types of actions we can associate with
this custom action…



We can

Navigate to a Form
for this list

We can Initiate a Workflow

Or, we can Navigate to a URL

We’re going to select Navigate to URL
, and enter in our URL,
and enter in our bogus URL, and pass a name/value pair of ItemURL={ItemUrl},
which was found by looking into the November 2009 version of the SharePoint 2010
SDK



OH NO! We can’t use it in Beta 2, which is the public beta we are running!
Ok, so I guess on the receiving end, we’ll need to fix it up in some other way.
So, we’ll just change our URL to pass a few things, and build the URL
ourselves.

http://www.grace-hunt.com/ULSLogComments?ItemURL={SiteUrl}/Lists/ULS
Logs/DispForm.aspx?ID={ItemId}


there, that should do the trick…

So, set your URL, and then give it a sequence number. This is the number in
which it appears in the list. Anything over 10000 is a good practice, so you do
not interfere with any other items in the list.



Then click OK
, and you now have a custom action, associated
with a list item, all without cracking open Visual Studio, deploying a package,
etc. etc.

You will now see it on the ULS Logs list dashboard page in SharePoint
Designer 2010



So, let’s go check out list… and there we have it, our custom action,
associated to the list item menu/edit control block, within our list!



And if we click it, we get an ugly, url encoded version

Logs/DispForm.aspx?ID=__cb40004300o4200b7983a57-53e7-de11-8ed4-000c29a9d0f1)
of:

Another cool thing, which you may notice, is that ALL list items have a
globally unique identifier in SharePoint 2010! YES! No more list item IDs
starting with 1, and going up from there.
