Hello Masoud,

I am unsure what the problem is. Are you perhaps setting the attached property to some collection? The stack trace says that you have a collection of charts and you are setting the attached property to that collection.

I am attaching a simple project with a single attached property. Upon setting the attached property, a message box is show. You can write your custom logic in the attached property changed handler. I hope this helps.

Hi Masoud,

I was unable to download the project. When I go to the indicated link, I see two gauges and two buttons. Even though I changed the language to English, not much of the content was in English and I didn't see a download button anywhere. I clicked on both of the buttons I see, but still could not download the project.

Have you examined the project I provided? Do you see any differences with your code?
