A common approach to handle this is through AJAX calls using jQuery. However, many developers encounter issues when trying to send multiple parameters effectively. If you're facing the problem of not being able to pass all parameters using $.ajax, you're in the right place. Let’s break down a solution to this problem. Understanding the Problem In your AJAX function, you create an object containing the product details, a numeric ID, and a name string. The goal is to pass this data to your OnPost method in Razor without including parameters in the URL. The Current Approach Your current AJAX method might look something like this: [[See Video to Reveal this Text or Code Snippet]] The problem arises when you reach the server, where your OnPost method only recognizes the product parameter and not the additional id and name parameters, leading to incomplete data handling. Proposed Solution Step 1: Transferring ID and Name into the Product Object One effective way to resolve this is to add the id and name properties to the product object before sending the AJAX request. Here’s how you can do it: [[See Video to Reveal this Text or Code Snippet]] Step 2: Updating the Razor PageModel Make sure your Razor OnPost method is capable of receiving the modified product object: [[See Video to Reveal this Text or Code Snippet]] Step 3: Model Modification (Optional) If necessary, and if you prefer to keep the structure of the Product model clean, you can also add id and name directly to your model using the [NotMapped] attribute. This way, they won’t be part of the database schema, but they will be accessible in your application.

By following the steps outlined above, you can create efficient and effective communication between your client-side and server-side code. Now, when you attempt to save your product using the AJAX function, all parameters will be sent correctly! Happy coding!
