Problem creating a Custom Ribbon Action to Order Lists

Question

I attempted to create my first Custom Ribbon action to allow users to sort list items. But I failed miserably. the Action wont show in my ribbon at all and I am having trouble finding out what is wrong. I created an empty element and stuck the following code inside.

<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">


  <CustomAction
          Id="Ribbon.Library.Actions.AddAButton"
          Location="CommandUI.Ribbon"
          RegistrationId="10000"
          RegistrationType="List">
    <CommandUIExtension>
      <CommandUIDefinitions>
        <CommandUIDefinition
          Location="Ribbon.List.Settings.Controls._children">
          <Button Id="Ribbon.Library.Share.NewRibbonButton"
            Command="NewRibbonButtonCommand"
            Image16by16="{SiteUrl}/_layouts/images/siteIcon.png"
            Image32by32="{SiteUrl}/_layouts/images/siteIcon.png"
            LabelText="Reorder Videos"
            TemplateAlias="o2" />
        </CommandUIDefinition>
      </CommandUIDefinitions>
      <CommandUIHandlers>
        <CommandUIHandler
          Command="NewRibbonButtonCommand"
          CommandAction="{SiteUrl}/_layouts/Reorder.aspx?List={ListId}" />
      </CommandUIHandlers>
    </CommandUIExtension>
  </CustomAction>

</Elements>

Answer 3

I used this article to add an Order Column to my List and add the action to my content type for the list item. This is working now.

Next I am trying to Sort by this column in Code using Visual Studio and a CAML query. Although when Using U2U CAML Builder it wont allow this column to be picked. It is a hidden internal column. Has anyone had success doing this??

Thanks.
