I want to display that flags-control on some of DNN's toolbars above my pages, so it can be accessible from every page.

I have read this in some of previous threads :

Dragan,

in an ascx file you have to register the control (at the top of the file, somewhere after the line that starts with "<%@ Control language=...":

<%@ Register TagPrefix="dnn" TagName="LANGUAGE" Src="~/Admin/Skins/Language.ascx" %>

Then you can add the control at the position you need it, like:

<dnn:LANGUAGE runat="server" id="LANGUAGE1"  showMenu="False" showLinks="True" />

Please have a look at this article in the blogs to get more information about the control: http://www.dnnsoftware.com/community-...

Happy DNNing!
