edit: if create style setter in code this:

system.windows.style style = new style(); style.setters.add(new setter(xceed.wpf.toolkit.messagebox.closebuttonvisibilityproperty,  visibility.hidden));  messagebox.style = style;

i exception:

an exception of type 'system.invalidoperationexception' occurred in xceed.wpf.toolkit.dll not handled in user code

additional information: close button on messagebox visible.

according link there closebuttonvisibility property can or set visibility of close button, try setting 'false'
