Current Navigation, Global Navigation, siblings and PublishingWeb?

Yes yes.. that's what was in my head during my quest to change the following options in the Navigation page.

I managed to change the global navigation use the following code:

web.Navigation.UseShared = true;
web.Update;

So how do you change the current navigation? Well, remember that the 'Navigation' link only becomes available when you activate the Office Sharepoint Server Publishing Infrastructure feature? Searching the online SDK I found the following class : PublishingWeb. This class which uses SPWeb has the following property : NavigationShowSiblings. When you set this boolean to true, the current navigation section will change to the desired option (as selected in the screenshot)!

Together with my colleague Servé Hermans we (indepently) searched for the solution and it was quite scary when I found the solution he also, at the same time, found the same page and thus the solution ;)
 
You might wonder why on earth we want to do this programmatically.. well we are working with a migrated environment where we are replacing our custom navigation webpart with the quicklaunch showing all the subsites (securitytrimmed ofcourse!). In order to make this work properly we have to set all the individual subsites to use that 'current navigation' property. Basically the code looks like this :

SPSite site = new SPSite("http://<sitename>");
foreach (SPWeb web in site.AllWebs)
{
    try
    {
        if (PublishingWeb.IsPublishingWeb(web))
        {
            PublishingWeb publishingWeb = PublishingWeb.GetPublishingWeb(web);
            publishingWeb.NavigationShowSiblings = true;
            publishingWeb.Update();
        }
    }

    catch (Exception error)
    {
        Console.WriteLine(error.Message.ToString());
    }
                     
    web.Close();
    web.Dispose();
}
site.Close();
site.Dispose();
