Localize a CustomAction programmatically

Question

I work in a farm environment and i want to add a CustomAction in a specific SPList. The list is created programmatically, so i cannot know the ID. For that i tried to register the action with RegistrationId="{$ListId:Lists/MyList;}".

<CustomAction
    Id="MyCustomAction"
    Location="CommandUI.Ribbon.ListView"
    RegistrationType="List"
    RegistrationId="{$ListId:Lists/MyList;}">

    ...

</CustomAction>

As i read and figure out, there is a bug in farm environment and i cannot register the action this way. I decided to add the action programmatically

SPUserCustomAction action = splist.UserCustomActions.Add();
action.Location = "CommandUI.Ribbon.ListView";
action.CommandUIExtension = @"
    <CommandUIExtension xmlns='http://schemas.microsoft.com/sharepoint/'>
        <CommandUIDefinitions>
            <CommandUIDefinition Location='Ribbon.ListItem.Actions.Controls._children'>
                <Button
                    Id='MyCustomActionButton'
                    Command='MyCustomActionCommand'
                    Image16by16='/_images/info_16x16.png'
                    Image32by32='/_images/info_32x32.png'
                    LabelText='$Resources:MyResources,Title;'
                    TemplateAlias='o1'
                    Sequence='25'
                />
            </CommandUIDefinition>
        </CommandUIDefinitions>

        ...

    </CommandUIExtension>
";
action.Update();

Now action is registered successfully but the problem is with the button label text. How it can be localized through code?

EDIT

There is the property CommandUIExtensionResource in SPUserCustomAction, that i suppose i could use, but i cannot find any example. I have use TitleResource in SPList, but the same usage in this case does not work.

Answer 1

I have the same problem. It seems to be that there is no way to add programmatically a localizable custom action.

Declarative custom actions are localizable. But to target them to a specific list in a declarative way we need to make templates of the custom list. I did not found a way to build a template for external lists.

So it seems to be impossible to add localizable custom actions to a specific external list.

Just because RegistrationId="{$ListId:Lists/MyList;}" does not work in farm solutions.

Do you have solved your problem?

you can use MS SPUtility class to read resource files:

SPUtility.GetLocalizedString(
string.Format("$Resources:{0}", resourceKey), 
"name of your resource file", 
(uint)SPContext.Current.Web.Locale.LCID
);

Hope it helps,

You can also use GetGlobalResourceObject to get the localized string

HttpContext.GetGlobalResourceObject("name of your resource file", "resourceKey").ToString();
