Trouble adding a button to the ListItem Ribbon

Question

I'm very new to to sharepoint and found a tutorial to allow me to create a custom action in order to place a button on the ribbon. I'm trying to use that to add a button to a list view but It isn't working.

Here is the tutorial xml to add a button to the shared doc library:

<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
<CustomAction
       Id="DemoHelloWorldButton"
       RegistrationId="101"
       RegistrationType="List"
       Location="CommandUI.Ribbon"
       Sequence="5"
       Title="Hello World">
        <CommandUIExtension>
          <CommandUIDefinitions>
            <CommandUIDefinition
             Location="Ribbon.Documents.Manage.Controls._children">
              <Button
               Id="DemoHelloWorldButton"
               Alt="Hello World Ribbon Button"
               Sequence="10"
               Command="Demo_HelloWorld"
               Image32by32="/_layouts/images/MyProject/img.jpg"
               LabelText="Hello World Demo"
               TemplateAlias="o1"/>
            </CommandUIDefinition>
          </CommandUIDefinitions>
          <CommandUIHandlers>
            <CommandUIHandler
             Command="Demo_HelloWorld"
             CommandAction="javascript:alert('Hello World!');"
             />
          </CommandUIHandlers>
        </CommandUIExtension>
      </CustomAction>
    </Elements>

This works great, and following some instructions online I've tried using firebug to determine the location so that I can add it this for lists. Based on what I'm seeing in firebug I should be able to make this change:

<CommandUIDefinition Location="Ribbon.ListItem.Manage.Controls._children"/>

However this isn't working at all and I've been unable to find any help. Most of the examples online are the either the same Shared Docs example, or they are using list the way I am. Thank you for taking a look at my question.

Answer 1

From your question it would seems that you need to add the new custom action button on list (your sample use a document library). If that is the case, you need to change the registation id from 101 (which identifies Document Library) to 100 (generic list). (Notice: please leave a comment if you needed something different or if this answer doesn't fully resolve your problem - I will try to update when I can).

About retriving your list RegistrationID. This blog post provides a list of ids for the main list templates found in SharePoint - haven't checked them all but they should be valid. Anyway, if any problem should arise, doublecheck with some other source as well.

Also, if the need should arise, you can use any tool like SharePoint manager to confirm the id of a given list. Simple navigate to the list and open the schema.xml tab. The value of the attribute "ServerTemplate" is the value you need.
