Hi folks:

I'm trying to find the toplevel tabid given a tabid for a submenu or sub-submenu...Well you get the diea. Is there a DNN core function to get this? I've been poring over the core code, but haven't found a way to do this. Thanks for any input!

Well, it *is* the weekend. ;-) How about this question. What does the GetTabsByParentID() function do? Does it return an array list of all the parents of a given tab, or does it list all tabs for the parent of a tab? Anyone? Buehler? Buehler?

PortalSettings.ActiveTab.BreadCrumbs should help

Yeah, ended up realizing it's a sql store proc, and looked at it. It returns all the tabs for the parent (only for one level). So it didn't do what I wanated. I finally found where 'PortalSettings' was defined in the class browser (actually PortalController and TabController). Man, why don't they have a search capability for the Class Browser in ASP.NET? It's like a zoo in there. ;-)

For search, I usually just search the Source Code if I have it.
If you don't have Source then you might want to use Lutz Roeder's Reflector which has search capability.

Yeah, that's actually how I found it. Used UE looked for all instances of PortalSettings, and in global.ascx found it was instantiated froma PortalController I think. I don't remember it was so late. ;-) But for anyone else out there, you traverse the Tabs using a TabController, which you use to get TabInfo object, which holds all the info for a Tab...

The function I use

Public Function GetTopTabID() As Integer

Dim objTabs As New TabController

Dim objTab As TabInfo

objTab = objTabs.GetTab(_portalSettings.ActiveTab.TabId)

While objTab.ParentId <> -1

objTab = objTabs.GetTab(objTab.ParentId)

End While

Return objTab.TabID

End Function

That is a very expensive way of doing that. I'll admit that I have no alternative but each objTabs.GetTab is a trip to the database. Isn't all this information already present in the ModuleBase? After all the menu already got rendered and it used the same data. Was it thrown away after the menu was drawn?

yeah its not the best way but i couldnt find any other way of doing this and most of it is cached anyway so in reality it just takes a few miliseconds to do thi call

PortalSettings.ActiveTab.BreadCrumbs is an ArrayList of all the ancestor TabInfo objects.

To get the Top Most TabId of the active tab you can use something like this:

Ctype(PortalSettings.ActiveTab.BreadCrumbs(0),TabInfo).TabID

No extra call to the DB is needed. PortalSettings is populated with a ton of information and cached for the request, making extra DB calls uneccessary in most cases.
