I'm sorry, but this is a code dump that no one will try to unravel. You would need to point out the lines which seem to contain the error as indicated by the exception.

I observed one fact . (I no longer want to ask question in this forum. No body are paid for answers. in fact I too not a professional developer. I am only an enthusiast who learn himself, I too not paid for my questions.) if I give less details people will blame that my questions are less informative. if I give all information people will say it is a code dumb; what a fun. for more precise in this case the exception occur due to x:Name in the resource dictionary.

If you are not prepared to strip down your code snippet through the process of elimination and present the problematic code to clarify your problem, then this is not the forum you are looking for.
