Put your question (problem) outside the codeblocks, it's hidden now.
What do you exactly want to do? Do you want to change the background color of few elements on your listbox? Describe it more precisely :)
As I can see you bind the ItemBackground property to your Grid Background, so just change the ItemBackground of elements you want in your source collection.
