Using Blend, I could apply new style as follows,
I just need to insert a new button on the Tab of document.
In order to do that, I created above style by selecting "Edit a template" menu in Blend.
However, there is a serious problem.
Close button is disabled!
Is there another workaround to insert a new control in Document Tab or fix this problem?
Thanks, in advance.
