I am currently creating a basic Library Management system for self-learning purposes. I’m using WPF for my frontend and I currently have the list of books displayed to the user, the issue is, although I have it set so when the book image is clicked a popup is displayed, nothing happens. Here is my code:

I’ve tried adding a breakpoint in the “BookImage_MouseLeftButtonUp” function to see if it even enters the function at least but it doesn’t which leads me to believe the issue is with the XAML itself and not the code because nothing executes to begin with. I’m not even sure if something is overlapping or what is wrong exactly. For context as well, if it makes any difference, The XAML code I provided is part of a MainWindow XAML file that has 4 tabs, one of them being a “Books” tab where the XAML I provided above is being displayed after clicking on that tab ofcourse.
