I would like to make the OK and cancel buttons in the tool settings panel visible when using RadImageEditorUI. I found this thread: http://www.telerik.com/forums/how-to-make-settings-buttion-visible which explains that the buttons do exist but are collapsed by the default template.
So I've tried adding the style from that thread (with the visibility removed) to the resources of my Window containing the RadImageEditorUI. However this modified style does not seem to actually get applied. Instead the default style with the collapsed button is used.
How can I make sure that this style is used or otherwise make these buttons visible?
