As the title of this post already says: I'm trying to toggle an icon in my tabcontainer.
I got a TabContainer with some ContentPanes in it.
If I get some values from the database I show them in the ContentPane and set the IconClass so the user see that there is some data.
In the my ContentPane I also got a delete and a save button.
If there was some data and the delete button is pressed I'd like to remove or to hide the Icon in the Tab.
Of course I want to do the other way, too.
But how do I do it?
I tried it with registry.byId("myIdOfTheContentPaneWhereTheIconClasswasDefined").className="dijitNoIcon"
without an effect.
Any ideas?
