As you may have noticed I have added X button and click event

But I don't know how to close it? What is the code?

    Hello Marko,

     

    I have been looking into your question and I am not sure that do you want to close. Do you want to detach the event handler?

     

    I will be looking forward to hearing from you.

     

    Sincerely,
