Container overrides default style

I have a 3rd party control in which i have added a toolbar in it's header container. The toolbar and child items show no开发者_JAVA百科rmally but the selection styling (highlighting of the child items) doesn't trigger. Somehow the header container overrides this. Is there anything i could do to prevent this?

You'd have to check why exactly this is happening first. Assuming that something is being overwritten is a first step, but you'd have to find out exactly what it is.

I suggest you try Snoop - It allows you to see what is the exact Visual Tree of your application - If you are correct then you will see which property is overridden by which control.
